create-user-pool¶

Description¶

Note

This action might generate an SMS text message. Starting June 1, 2021, US telecom carriers require you to register an origination phone number before you can send SMS messages to US phone numbers. If you use SMS text messages in Amazon Cognito, you must register a phone number with Amazon Pinpoint . Amazon Cognito uses the registered number automatically. Otherwise, Amazon Cognito users who must receive SMS messages might not be able to sign up, activate their accounts, or sign in.

If you have never used SMS text messages with Amazon Cognito or any other Amazon Web Services service, Amazon Simple Notification Service might place your account in the SMS sandbox. In * sandbox mode * , you can send messages only to verified phone numbers. After you test your app while in the sandbox environment, you can move out of the sandbox and into production. For more information, see SMS message settings for Amazon Cognito user pools in the Amazon Cognito Developer Guide .

Creates a new Amazon Cognito user pool and sets the password policy for the pool.

Warning

If you don't provide a value for an attribute, Amazon Cognito sets it to its default value.

Note

Amazon Cognito evaluates Identity and Access Management (IAM) policies in requests for this API operation. For this operation, you must use IAM credentials to authorize requests, and you must grant yourself the corresponding IAM permission in a policy.

Options¶

--pool-name (string)

A string used to name the user pool.

--policies (structure)

The policies associated with the new user pool.

PasswordPolicy -> (structure)

The password policy settings for a user pool, including complexity, history, and length requirements.

MinimumLength -> (integer)

The minimum length of the password in the policy that you have set. This value can't be less than 6.

RequireUppercase -> (boolean)

The requirement in a password policy that users must include at least one uppercase letter in their password.

RequireLowercase -> (boolean)

The requirement in a password policy that users must include at least one lowercase letter in their password.

RequireNumbers -> (boolean)

The requirement in a password policy that users must include at least one number in their password.

RequireSymbols -> (boolean)

The requirement in a password policy that users must include at least one symbol in their password.

PasswordHistorySize -> (integer)

The number of previous passwords that you want Amazon Cognito to restrict each user from reusing. Users can't set a password that matches any of n previous passwords, where n is the value of PasswordHistorySize .

Password history isn't enforced and isn't displayed in DescribeUserPool responses when you set this value to 0 or don't provide it. To activate this setting, advanced security features must be active in your user pool.

TemporaryPasswordValidityDays -> (integer)

The number of days a temporary password is valid in the password policy. If the user doesn't sign in during this time, an administrator must reset their password. Defaults to 7 . If you submit a value of 0 , Amazon Cognito treats it as a null value and sets TemporaryPasswordValidityDays to its default value.

Note
When you set TemporaryPasswordValidityDays for a user pool, you can no longer set a value for the legacy UnusedAccountValidityDays parameter in that user pool.

SignInPolicy -> (structure)

The policy for allowed types of authentication in a user pool.

AllowedFirstAuthFactors -> (list)

The sign-in methods that a user pool supports as the first factor. You can permit users to start authentication with a standard username and password, or with other one-time password and hardware factors.

(string)

Shorthand Syntax:

OPTIONAL

--user-attribute-update-settings (structure)

The settings for updates to user attributes. These settings include the property AttributesRequireVerificationBeforeUpdate , a user-pool setting that tells Amazon Cognito how to handle changes to the value of your users' email address and phone number attributes. For more information, see Verifying updates to email addresses and phone numbers .

AttributesRequireVerificationBeforeUpdate -> (list)

Requires that your user verifies their email address, phone number, or both before Amazon Cognito updates the value of that attribute. When you update a user attribute that has this option activated, Amazon Cognito sends a verification message to the new phone number or email address. Amazon Cognito doesn’t change the value of the attribute until your user responds to the verification message and confirms the new value.

You can verify an updated email address or phone number with a VerifyUserAttribute API request. You can also call the AdminUpdateUserAttributes API and set email_verified or phone_number_verified to true.

When AttributesRequireVerificationBeforeUpdate is false, your user pool doesn't require that your users verify attribute changes before Amazon Cognito updates them. In a user pool where AttributesRequireVerificationBeforeUpdate is false, API operations that change attribute values can immediately update a user’s email or phone_number attribute.

(string)

Shorthand Syntax:

AttributesRequireVerificationBeforeUpdate=string,string

JSON Syntax:

{
  "AttributesRequireVerificationBeforeUpdate": ["phone_number"|"email", ...]
}

--device-configuration (structure)

The device-remembering configuration for a user pool. A null value indicates that you have deactivated device remembering in your user pool.

Note
When you provide a value for any DeviceConfiguration field, you activate the Amazon Cognito device-remembering feature.

ChallengeRequiredOnNewDevice -> (boolean)

When true, a remembered device can sign in with device authentication instead of SMS and time-based one-time password (TOTP) factors for multi-factor authentication (MFA).

Note
Whether or not ChallengeRequiredOnNewDevice is true, users who sign in with devices that have not been confirmed or remembered must still provide a second factor in a user pool that requires MFA.

DeviceOnlyRememberedOnUserPrompt -> (boolean)

When true, Amazon Cognito doesn't automatically remember a user's device when your app sends a ConfirmDevice API request. In your app, create a prompt for your user to choose whether they want to remember their device. Return the user's choice in an UpdateDeviceStatus API request.

When DeviceOnlyRememberedOnUserPrompt is false , Amazon Cognito immediately remembers devices that you register in a ConfirmDevice API request.

Shorthand Syntax:

ChallengeRequiredOnNewDevice=boolean,DeviceOnlyRememberedOnUserPrompt=boolean

JSON Syntax:

{
  "ChallengeRequiredOnNewDevice": true|false,
  "DeviceOnlyRememberedOnUserPrompt": true|false
}

--email-configuration (structure)

The email configuration of your user pool. The email configuration type sets your preferred sending method, Amazon Web Services Region, and sender for messages from your user pool.

SourceArn -> (string)

The ARN of a verified email address or an address from a verified domain in Amazon SES. You can set a SourceArn email from a verified domain only with an API request. You can set a verified email address, but not an address in a verified domain, in the Amazon Cognito console. Amazon Cognito uses the email address that you provide in one of the following ways, depending on the value that you specify for the EmailSendingAccount parameter:

If you specify COGNITO_DEFAULT , Amazon Cognito uses this address as the custom FROM address when it emails your users using its built-in email account.

If you specify DEVELOPER , Amazon Cognito emails your users with this address by calling Amazon SES on your behalf.

The Region value of the SourceArn parameter must indicate a supported Amazon Web Services Region of your user pool. Typically, the Region in the SourceArn and the user pool Region are the same. For more information, see Amazon SES email configuration regions in the Amazon Cognito Developer Guide .

ReplyToEmailAddress -> (string)

The destination to which the receiver of the email should reply.

EmailSendingAccount -> (string)

Specifies whether Amazon Cognito uses its built-in functionality to send your users email messages, or uses your Amazon Simple Email Service email configuration. Specify one of the following values:

COGNITO_DEFAULT

When Amazon Cognito emails your users, it uses its built-in email functionality. When you use the default option, Amazon Cognito allows only a limited number of emails each day for your user pool. For typical production environments, the default email limit is less than the required delivery volume. To achieve a higher delivery volume, specify DEVELOPER to use your Amazon SES email configuration.

To look up the email delivery limit for the default option, see Limits in the Amazon Cognito Developer Guide .

The default FROM address is no-reply@verificationemail.com . To customize the FROM address, provide the Amazon Resource Name (ARN) of an Amazon SES verified email address for the SourceArn parameter.

DEVELOPER

When Amazon Cognito emails your users, it uses your Amazon SES configuration. Amazon Cognito calls Amazon SES on your behalf to send email from your verified email address. When you use this option, the email delivery limits are the same limits that apply to your Amazon SES verified email address in your Amazon Web Services account.

If you use this option, provide the ARN of an Amazon SES verified email address for the SourceArn parameter.

Before Amazon Cognito can email your users, it requires additional permissions to call Amazon SES on your behalf. When you update your user pool with this option, Amazon Cognito creates a service-linked role , which is a type of role in your Amazon Web Services account. This role contains the permissions that allow you to access Amazon SES and send email messages from your email address. For more information about the service-linked role that Amazon Cognito creates, see Using Service-Linked Roles for Amazon Cognito in the Amazon Cognito Developer Guide .

From -> (string)

Either the sender’s email address or the sender’s name with their email address. For example, testuser@example.com or Test User <testuser@example.com> . This address appears before the body of the email.

ConfigurationSet -> (string)

The set of configuration rules that can be applied to emails sent using Amazon Simple Email Service. A configuration set is applied to an email by including a reference to the configuration set in the headers of the email. Once applied, all of the rules in that configuration set are applied to the email. Configuration sets can be used to apply the following types of rules to emails:

Event publishing

Amazon Simple Email Service can track the number of send, delivery, open, click, bounce, and complaint events for each email sent. Use event publishing to send information about these events to other Amazon Web Services services such as and Amazon CloudWatch

IP pool management

When leasing dedicated IP addresses with Amazon Simple Email Service, you can create groups of IP addresses, called dedicated IP pools. You can then associate the dedicated IP pools with configuration sets.

Shorthand Syntax:

SourceArn=string,ReplyToEmailAddress=string,EmailSendingAccount=string,From=string,ConfigurationSet=string

JSON Syntax:

{
  "SourceArn": "string",
  "ReplyToEmailAddress": "string",
  "EmailSendingAccount": "COGNITO_DEFAULT"|"DEVELOPER",
  "From": "string",
  "ConfigurationSet": "string"
}

--sms-configuration (structure)

The SMS configuration with the settings that your Amazon Cognito user pool must use to send an SMS message from your Amazon Web Services account through Amazon Simple Notification Service. To send SMS messages with Amazon SNS in the Amazon Web Services Region that you want, the Amazon Cognito user pool uses an Identity and Access Management (IAM) role in your Amazon Web Services account.

SnsCallerArn -> (string)

The Amazon Resource Name (ARN) of the Amazon SNS caller. This is the ARN of the IAM role in your Amazon Web Services account that Amazon Cognito will use to send SMS messages. SMS messages are subject to a spending limit .

ExternalId -> (string)

The external ID provides additional security for your IAM role. You can use an ExternalId with the IAM role that you use with Amazon SNS to send SMS messages for your user pool. If you provide an ExternalId , your Amazon Cognito user pool includes it in the request to assume your IAM role. You can configure the role trust policy to require that Amazon Cognito, and any principal, provide the ExternalID . If you use the Amazon Cognito Management Console to create a role for SMS multi-factor authentication (MFA), Amazon Cognito creates a role with the required permissions and a trust policy that demonstrates use of the ExternalId .

For more information about the ExternalId of a role, see How to use an external ID when granting access to your Amazon Web Services resources to a third party .

SnsRegion -> (string)

The Amazon Web Services Region to use with Amazon SNS integration. You can choose the same Region as your user pool, or a supported Legacy Amazon SNS alternate Region .

Amazon Cognito resources in the Asia Pacific (Seoul) Amazon Web Services Region must use your Amazon SNS configuration in the Asia Pacific (Tokyo) Region. For more information, see SMS message settings for Amazon Cognito user pools .

Shorthand Syntax:

SnsCallerArn=string,ExternalId=string,SnsRegion=string

JSON Syntax:

{
  "SnsCallerArn": "string",
  "ExternalId": "string",
  "SnsRegion": "string"
}

--user-pool-tags (map)

The tag keys and values to assign to the user pool. A tag is a label that you can use to categorize and manage user pools in different ways, such as by purpose, owner, environment, or other criteria.

key -> (string)

value -> (string)

Shorthand Syntax:

KeyName1=string,KeyName2=string

JSON Syntax:

{"string": "string"
  ...}

--admin-create-user-config (structure)

The configuration for AdminCreateUser requests.

AllowAdminCreateUserOnly -> (boolean)

The setting for allowing self-service sign-up. When true , only administrators can create new user profiles. When false , users can register themselves and create a new user profile with the SignUp operation.

UnusedAccountValidityDays -> (integer)

This parameter is no longer in use. Configure the duration of temporary passwords with the TemporaryPasswordValidityDays parameter of PasswordPolicyType . For older user pools that have a UnusedAccountValidityDays configuration, that value is effective until you set a value for TemporaryPasswordValidityDays .

The password expiration limit in days for administrator-created users. When this time expires, the user can't sign in with their temporary password. To reset the account after that time limit, you must call AdminCreateUser again, specifying RESEND for the MessageAction parameter.

The default value for this parameter is 7.

InviteMessageTemplate -> (structure)

The template for the welcome message to new users. This template must include the {####} temporary password placeholder if you are creating users with passwords. If your users don't have passwords, you can omit the placeholder.

See also Customizing User Invitation Messages .

SMSMessage -> (string)

The message template for SMS messages.

EmailMessage -> (string)

The message template for email messages. EmailMessage is allowed only if EmailSendingAccount is DEVELOPER.

EmailSubject -> (string)

The subject line for email messages. EmailSubject is allowed only if EmailSendingAccount is DEVELOPER.

Shorthand Syntax:

AllowAdminCreateUserOnly=boolean,UnusedAccountValidityDays=integer,InviteMessageTemplate={SMSMessage=string,EmailMessage=string,EmailSubject=string}

  }
}

--schema (list)

An array of schema attributes for the new user pool. These attributes can be standard or custom attributes.

(structure)

A list of the user attributes and their properties in your user pool. The attribute schema contains standard attributes, custom attributes with a custom: prefix, and developer attributes with a dev: prefix. For more information, see User pool attributes .

Developer-only dev: attributes are a legacy feature of user pools, and are read-only to all app clients. You can create and update developer-only attributes only with IAM-authenticated API operations. Use app client read/write permissions instead.

This data type is a request and response parameter of CreateUserPool and UpdateUserPool , and a response parameter of DescribeUserPool .

Name -> (string)

The name of your user pool attribute. When you create or update a user pool, adding a schema attribute creates a custom or developer-only attribute. When you add an attribute with a Name value of MyAttribute , Amazon Cognito creates the custom attribute custom:MyAttribute . When DeveloperOnlyAttribute is true , Amazon Cognito creates your attribute as dev:MyAttribute . In an operation that describes a user pool, Amazon Cognito returns this value as value for standard attributes, custom:value for custom attributes, and dev:value for developer-only attributes..

AttributeDataType -> (string)

The data format of the values for your attribute. When you choose an AttributeDataType , Amazon Cognito validates the input against the data type. A custom attribute value in your user's ID token is always a string, for example "custom:isMember" : "true" or "custom:YearsAsMember" : "12" .

DeveloperOnlyAttribute -> (boolean)

Note
You should use WriteAttributes in the user pool client to control how attributes can be mutated for new use cases instead of using DeveloperOnlyAttribute .

Specifies whether the attribute type is developer only. This attribute can only be modified by an administrator. Users won't be able to modify this attribute using their access token. For example, DeveloperOnlyAttribute can be modified using AdminUpdateUserAttributes but can't be updated using UpdateUserAttributes.

Mutable -> (boolean)

Specifies whether the value of the attribute can be changed.

Any user pool attribute whose value you map from an IdP attribute must be mutable, with a parameter value of true . Amazon Cognito updates mapped attributes when users sign in to your application through an IdP. If an attribute is immutable, Amazon Cognito throws an error when it attempts to update the attribute. For more information, see Specifying Identity Provider Attribute Mappings for Your User Pool .

Required -> (boolean)

Specifies whether a user pool attribute is required. If the attribute is required and the user doesn't provide a value, registration or sign-in will fail.

NumberAttributeConstraints -> (structure)

Specifies the constraints for an attribute of the number type.

MinValue -> (string)

The minimum value of an attribute that is of the number data type.

MaxValue -> (string)

The maximum length of a number attribute value. Must be a number less than or equal to 2^1023 , represented as a string with a length of 131072 characters or fewer.

StringAttributeConstraints -> (structure)

Specifies the constraints for an attribute of the string type.

MinLength -> (string)

The minimum length of a string attribute value.

MaxLength -> (string)

When case sensitivity is set to False (case insensitive), users can sign in with any combination of capital and lowercase letters. For example, username , USERNAME , or UserName , or for email, email@example.com or EMaiL@eXamplE.Com . For most use cases, set case sensitivity to False (case insensitive) as a best practice. When usernames and email addresses are case insensitive, Amazon Cognito treats any variation in case as the same user, and prevents a case variation from being assigned to the same attribute for a different user.

This configuration is immutable after you set it. For more information, see UsernameConfigurationType .

CaseSensitive -> (boolean)

Specifies whether user name case sensitivity will be applied for all users in the user pool through Amazon Cognito APIs. For most use cases, set case sensitivity to False (case insensitive) as a best practice. When usernames and email addresses are case insensitive, users can sign in as the same user when they enter a different capitalization of their user name.

Valid values include:

true

Enables case sensitivity for all username input. When this option is set to true , users must sign in using the exact capitalization of their given username, such as “UserName”. This is the default value.

false

Enables case insensitivity for all username input. For example, when this option is set to false , users can sign in using username , USERNAME , or UserName . This option also enables both preferred_username and email alias to be case insensitive, in addition to the username attribute.

Shorthand Syntax:

CaseSensitive=boolean

JSON Syntax:

{
  "CaseSensitive": true|false
}

--account-recovery-setting (structure)

The available verified method a user can use to recover their password when they call ForgotPassword . You can use this setting to define a preferred method when a user has more than one method available. With this setting, SMS doesn't qualify for a valid password recovery mechanism if the user also has SMS multi-factor authentication (MFA) activated. In the absence of this setting, Amazon Cognito uses the legacy behavior to determine the recovery method where SMS is preferred through email.

RecoveryMechanisms -> (list)

The list of options and priorities for user message delivery in forgot-password operations. Sets or displays user pool preferences for email or SMS message priority, whether users should fall back to a second delivery method, and whether passwords should only be reset by administrators.

(structure)

A recovery option for a user. The AccountRecoverySettingType data type is an array of this object. Each RecoveryOptionType has a priority property that determines whether it is a primary or secondary option.

For example, if verified_email has a priority of 1 and verified_phone_number has a priority of 2 , your user pool sends account-recovery messages to a verified email address but falls back to an SMS message if the user has a verified phone number. The admin_only option prevents self-service account recovery.

This data type is a request and response parameter of CreateUserPool and UpdateUserPool , and a response parameter of DescribeUserPool .

Priority -> (integer)

Your priority preference for using the specified attribute in account recovery. The highest priority is 1 .

Name -> (string)

The recovery method that this object sets a recovery option for.

Shorthand Syntax:

RecoveryMechanisms=[{Priority=integer,Name=string},{Priority=integer,Name=string}]

JSON Syntax:

{
  "RecoveryMechanisms": [
    {
      "Priority": integer,
      "Name": "verified_email"|"verified_phone_number"|"admin_only"
    }
    ...
  ]
}

--user-pool-tier (string)

The user pool feature plan , or tier. This parameter determines the eligibility of the user pool for features like managed login, access-token customization, and threat protection. Defaults to ESSENTIALS .

Possible values:

LITE

ESSENTIALS

PLUS

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options¶

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

json
text
table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

on
off
auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Examples¶

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To create a minimally configured user pool

This example creates a user pool named MyUserPool using default values. There are no required attributes and no application clients. MFA and advanced security is disabled.

Command:

aws cognito-idp create-user-pool --pool-name MyUserPool

To create a user pool with two required attributes

This example creates a user pool MyUserPool. The pool is configured to accept email as a username attribute. It also sets the email source address to a validated address using Amazon Simple Email Service.

Command:

aws cognito-idp create-user-pool --pool-name MyUserPool --username-attributes "email" --email-configuration=SourceArn="arn:aws:ses:us-east-1:111111111111:identity/jane@example.com",ReplyToEmailAddress="jane@example.com"

PasswordHistorySize -> (integer)

The number of previous passwords that you want Amazon Cognito to restrict each user from reusing. Users can't set a password that matches any of n previous passwords, where n is the value of PasswordHistorySize .

Password history isn't enforced and isn't displayed in DescribeUserPool responses when you set this value to 0 or don't provide it. To activate this setting, advanced security features must be active in your user pool.

TemporaryPasswordValidityDays -> (integer)

The number of days a temporary password is valid in the password policy. If the user doesn't sign in during this time, an administrator must reset their password. Defaults to 7 . If you submit a value of 0 , Amazon Cognito treats it as a null value and sets TemporaryPasswordValidityDays to its default value.

Note
When you set TemporaryPasswordValidityDays for a user pool, you can no longer set a value for the legacy UnusedAccountValidityDays parameter in that user pool.

SignInPolicy -> (structure)

The policy for allowed types of authentication in a user pool.

CreationDate -> (timestamp)

The date and time when the item was created. Amazon Cognito returns this timestamp in UNIX epoch time format. Your SDK might render the output in a human-readable format like ISO 8601 or a Java Date object.

SchemaAttributes -> (list)

A list of the user attributes and their properties in your user pool. The attribute schema contains standard attributes, custom attributes with a custom: prefix, and developer attributes with a dev: prefix. For more information, see User pool attributes .

Developer-only attributes are a legacy feature of user pools, and are read-only to all app clients. You can create and update developer-only attributes only with IAM-authenticated API operations. Use app client read/write permissions instead.

(structure)

A list of the user attributes and their properties in your user pool. The attribute schema contains standard attributes, custom attributes with a custom: prefix, and developer attributes with a dev: prefix. For more information, see User pool attributes .

Developer-only dev: attributes are a legacy feature of user pools, and are read-only to all app clients. You can create and update developer-only attributes only with IAM-authenticated API operations. Use app client read/write permissions instead.

This data type is a request and response parameter of CreateUserPool and UpdateUserPool , and a response parameter of DescribeUserPool .

Name -> (string)

The name of your user pool attribute. When you create or update a user pool, adding a schema attribute creates a custom or developer-only attribute. When you add an attribute with a Name value of MyAttribute , Amazon Cognito creates the custom attribute custom:MyAttribute . When DeveloperOnlyAttribute is true , Amazon Cognito creates your attribute as dev:MyAttribute . In an operation that describes a user pool, Amazon Cognito returns this value as value for standard attributes, custom:value for custom attributes, and dev:value for developer-only attributes..

AttributeDataType -> (string)

The data format of the values for your attribute. When you choose an AttributeDataType , Amazon Cognito validates the input against the data type. A custom attribute value in your user's ID token is always a string, for example "custom:isMember" : "true" or "custom:YearsAsMember" : "12" .

DeveloperOnlyAttribute -> (boolean)

Note
You should use WriteAttributes in the user pool client to control how attributes can be mutated for new use cases instead of using DeveloperOnlyAttribute .

Specifies whether the attribute type is developer only. This attribute can only be modified by an administrator. Users won't be able to modify this attribute using their access token. For example, DeveloperOnlyAttribute can be modified using AdminUpdateUserAttributes but can't be updated using UpdateUserAttributes.

Mutable -> (boolean)

Specifies whether the value of the attribute can be changed.

Any user pool attribute whose value you map from an IdP attribute must be mutable, with a parameter value of true . Amazon Cognito updates mapped attributes when users sign in to your application through an IdP. If an attribute is immutable, Amazon Cognito throws an error when it attempts to update the attribute. For more information, see Specifying Identity Provider Attribute Mappings for Your User Pool .

Required -> (boolean)

Specifies whether a user pool attribute is required. If the attribute is required and the user doesn't provide a value, registration or sign-in will fail.

Specifies the constraints for an attribute of the number type.

MinValue -> (string)

The minimum value of an attribute that is of the number data type.

MaxValue -> (string)

The maximum length of a number attribute value. Must be a number less than or equal to 2^1023 , represented as a string with a length of 131072 characters or fewer.

StringAttributeConstraints -> (structure)

Specifies the constraints for an attribute of the string type.

MinLength -> (string)

The minimum length of a string attribute value.

VerificationMessageTemplate -> (structure)

The template for the verification message that your user pool delivers to users who set an email address or phone number attribute.

SmsMessage -> (string)

The template for SMS messages that Amazon Cognito sends to your users.

EmailMessage -> (string)

The template for email messages that Amazon Cognito sends to your users. You can set an EmailMessage template only if the value of EmailSendingAccount is DEVELOPER . When your EmailSendingAccount is DEVELOPER , your user pool sends email messages with your own Amazon SES configuration.

EmailSubject -> (string)

The subject line for the email message template. You can set an EmailSubject template only if the value of EmailSendingAccount is DEVELOPER . When your EmailSendingAccount is DEVELOPER , your user pool sends email messages with your own Amazon SES configuration.

EmailMessageByLink -> (string)

The email message template for sending a confirmation link to the user. You can set an EmailMessageByLink template only if the value of EmailSendingAccount is DEVELOPER . When your EmailSendingAccount is DEVELOPER , your user pool sends email messages with your own Amazon SES configuration.

EmailSubjectByLink -> (string)

The subject line for the email message template for sending a confirmation link to the user. You can set an EmailSubjectByLink template only if the value of EmailSendingAccount is DEVELOPER . When your EmailSendingAccount is DEVELOPER , your user pool sends email messages with your own Amazon SES configuration.

DefaultEmailOption -> (string)

The configuration of verification emails to contain a clickable link or a verification code.

For link, your template body must contain link text in the format {##Click here##} . "Click here" in the example is a customizable string. For code, your template body must contain a code placeholder in the format {####} .

SmsAuthenticationMessage -> (string)

The contents of the SMS authentication message.

UserAttributeUpdateSettings -> (structure)

The settings for updates to user attributes. These settings include the property AttributesRequireVerificationBeforeUpdate , a user-pool setting that tells Amazon Cognito how to handle changes to the value of your users' email address and phone number attributes. For more information, see Verifying updates to email addresses and phone numbers .

AttributesRequireVerificationBeforeUpdate -> (list)

Requires that your user verifies their email address, phone number, or both before Amazon Cognito updates the value of that attribute. When you update a user attribute that has this option activated, Amazon Cognito sends a verification message to the new phone number or email address. Amazon Cognito doesn’t change the value of the attribute until your user responds to the verification message and confirms the new value.

You can verify an updated email address or phone number with a VerifyUserAttribute API request. You can also call the AdminUpdateUserAttributes API and set email_verified or phone_number_verified to true.

When AttributesRequireVerificationBeforeUpdate is false, your user pool doesn't require that your users verify attribute changes before Amazon Cognito updates them. In a user pool where AttributesRequireVerificationBeforeUpdate is false, API operations that change attribute values can immediately update a user’s email or phone_number attribute.

(string)

MfaConfiguration -> (string)

Can be one of the following values:

OFF - MFA tokens aren't required and can't be specified during user registration.

ON - MFA tokens are required for all user registrations. You can only specify required when you're initially creating a user pool.

OPTIONAL - Users have the option when registering to create an MFA token.

DeviceConfiguration -> (structure)

The device-remembering configuration for a user pool. A null value indicates that you have deactivated device remembering in your user pool.

Note
When you provide a value for any DeviceConfiguration field, you activate the Amazon Cognito device-remembering feature.

ChallengeRequiredOnNewDevice -> (boolean)

When true, a remembered device can sign in with device authentication instead of SMS and time-based one-time password (TOTP) factors for multi-factor authentication (MFA).

Note
Whether or not ChallengeRequiredOnNewDevice is true, users who sign in with devices that have not been confirmed or remembered must still provide a second factor in a user pool that requires MFA.

DeviceOnlyRememberedOnUserPrompt -> (boolean)

When true, Amazon Cognito doesn't automatically remember a user's device when your app sends a ConfirmDevice API request. In your app, create a prompt for your user to choose whether they want to remember their device. Return the user's choice in an UpdateDeviceStatus API request.

When DeviceOnlyRememberedOnUserPrompt is false , Amazon Cognito immediately remembers devices that you register in a ConfirmDevice API request.

EstimatedNumberOfUsers -> (integer)

A number estimating the size of the user pool.

EmailConfiguration -> (structure)

The email configuration of your user pool. The email configuration type sets your preferred sending method, Amazon Web Services Region, and sender for messages from your user pool.

SourceArn -> (string)

The ARN of a verified email address or an address from a verified domain in Amazon SES. You can set a SourceArn email from a verified domain only with an API request. You can set a verified email address, but not an address in a verified domain, in the Amazon Cognito console. Amazon Cognito uses the email address that you provide in one of the following ways, depending on the value that you specify for the EmailSendingAccount parameter:

If you specify COGNITO_DEFAULT , Amazon Cognito uses this address as the custom FROM address when it emails your users using its built-in email account.

If you specify DEVELOPER , Amazon Cognito emails your users with this address by calling Amazon SES on your behalf.

The Region value of the SourceArn parameter must indicate a supported Amazon Web Services Region of your user pool. Typically, the Region in the SourceArn and the user pool Region are the same. For more information, see Amazon SES email configuration regions in the Amazon Cognito Developer Guide .

ReplyToEmailAddress -> (string)

The destination to which the receiver of the email should reply.

EmailSendingAccount -> (string)

Specifies whether Amazon Cognito uses its built-in functionality to send your users email messages, or uses your Amazon Simple Email Service email configuration. Specify one of the following values:

COGNITO_DEFAULT

When Amazon Cognito emails your users, it uses its built-in email functionality. When you use the default option, Amazon Cognito allows only a limited number of emails each day for your user pool. For typical production environments, the default email limit is less than the required delivery volume. To achieve a higher delivery volume, specify DEVELOPER to use your Amazon SES email configuration.

To look up the email delivery limit for the default option, see Limits in the Amazon Cognito Developer Guide .

The default FROM address is no-reply@verificationemail.com . To customize the FROM address, provide the Amazon Resource Name (ARN) of an Amazon SES verified email address for the SourceArn parameter.

DEVELOPER

When Amazon Cognito emails your users, it uses your Amazon SES configuration. Amazon Cognito calls Amazon SES on your behalf to send email from your verified email address. When you use this option, the email delivery limits are the same limits that apply to your Amazon SES verified email address in your Amazon Web Services account.

If you use this option, provide the ARN of an Amazon SES verified email address for the SourceArn parameter.

Before Amazon Cognito can email your users, it requires additional permissions to call Amazon SES on your behalf. When you update your user pool with this option, Amazon Cognito creates a service-linked role , which is a type of role in your Amazon Web Services account. This role contains the permissions that allow you to access Amazon SES and send email messages from your email address. For more information about the service-linked role that Amazon Cognito creates, see Using Service-Linked Roles for Amazon Cognito in the Amazon Cognito Developer Guide .

From -> (string)

Either the sender’s email address or the sender’s name with their email address. For example, testuser@example.com or Test User <testuser@example.com> . This address appears before the body of the email.

ConfigurationSet -> (string)

The set of configuration rules that can be applied to emails sent using Amazon Simple Email Service. A configuration set is applied to an email by including a reference to the configuration set in the headers of the email. Once applied, all of the rules in that configuration set are applied to the email. Configuration sets can be used to apply the following types of rules to emails:

Event publishing

Amazon Simple Email Service can track the number of send, delivery, open, click, bounce, and complaint events for each email sent. Use event publishing to send information about these events to other Amazon Web Services services such as and Amazon CloudWatch

IP pool management

When leasing dedicated IP addresses with Amazon Simple Email Service, you can create groups of IP addresses, called dedicated IP pools. You can then associate the dedicated IP pools with configuration sets.

SmsConfiguration -> (structure)

User pool configuration for delivery of SMS messages with Amazon Simple Notification Service. To send SMS messages with Amazon SNS in the Amazon Web Services Region that you want, the Amazon Cognito user pool uses an Identity and Access Management (IAM) role in your Amazon Web Services account.

SnsCallerArn -> (string)

The Amazon Resource Name (ARN) of the Amazon SNS caller. This is the ARN of the IAM role in your Amazon Web Services account that Amazon Cognito will use to send SMS messages. SMS messages are subject to a spending limit .

ExternalId -> (string)

The external ID provides additional security for your IAM role. You can use an ExternalId with the IAM role that you use with Amazon SNS to send SMS messages for your user pool. If you provide an ExternalId , your Amazon Cognito user pool includes it in the request to assume your IAM role. You can configure the role trust policy to require that Amazon Cognito, and any principal, provide the ExternalID . If you use the Amazon Cognito Management Console to create a role for SMS multi-factor authentication (MFA), Amazon Cognito creates a role with the required permissions and a trust policy that demonstrates use of the ExternalId .

For more information about the ExternalId of a role, see How to use an external ID when granting access to your Amazon Web Services resources to a third party .

SnsRegion -> (string)

The Amazon Web Services Region to use with Amazon SNS integration. You can choose the same Region as your user pool, or a supported Legacy Amazon SNS alternate Region .

Amazon Cognito resources in the Asia Pacific (Seoul) Amazon Web Services Region must use your Amazon SNS configuration in the Asia Pacific (Tokyo) Region. For more information, see SMS message settings for Amazon Cognito user pools .

UserPoolTags -> (map)

The tags that are assigned to the user pool. A tag is a label that you can apply to user pools to categorize and manage them in different ways, such as by purpose, owner, environment, or other criteria.

key -> (string)

value -> (string)

SmsConfigurationFailure -> (string)

The reason why the SMS configuration can't send the messages to your users.

This message might include comma-separated values to describe why your SMS configuration can't send messages to user pool end users.

InvalidSmsRoleAccessPolicyException

The Identity and Access Management role that Amazon Cognito uses to send SMS messages isn't properly configured. For more information, see SmsConfigurationType .

SNSSandbox

The Amazon Web Services account is in the SNS SMS Sandbox and messages will only reach verified end users. This parameter won’t get populated with SNSSandbox if the user creating the user pool doesn’t have SNS permissions. To learn how to move your Amazon Web Services account out of the sandbox, see Moving out of the SMS sandbox .

EmailConfigurationFailure -> (string)

Deprecated. Review error codes from API requests with EventSource:cognito-idp.amazonaws.com in CloudTrail for information about problems with user pool email configuration.

Domain -> (string)

The domain prefix, if the user pool has a domain associated with it.

CustomDomain -> (string)

A custom domain name that you provide to Amazon Cognito. This parameter applies only if you use a custom domain to host the sign-up and sign-in pages for your application. An example of a custom domain name might be auth.example.com .

For more information about adding a custom domain to your user pool, see Using Your Own Domain for the Hosted UI .

AdminCreateUserConfig -> (structure)

The configuration for AdminCreateUser requests.

AllowAdminCreateUserOnly -> (boolean)

The setting for allowing self-service sign-up. When true , only administrators can create new user profiles. When false , users can register themselves and create a new user profile with the SignUp operation.

UnusedAccountValidityDays -> (integer)

This parameter is no longer in use. Configure the duration of temporary passwords with the TemporaryPasswordValidityDays parameter of PasswordPolicyType . For older user pools that have a UnusedAccountValidityDays configuration, that value is effective until you set a value for TemporaryPasswordValidityDays .

The password expiration limit in days for administrator-created users. When this time expires, the user can't sign in with their temporary password. To reset the account after that time limit, you must call AdminCreateUser again, specifying RESEND for the MessageAction parameter.

The default value for this parameter is 7.

InviteMessageTemplate -> (structure)

The template for the welcome message to new users. This template must include the {####} temporary password placeholder if you are creating users with passwords. If your users don't have passwords, you can omit the placeholder.

See also Customizing User Invitation Messages .

SMSMessage -> (string)

The message template for SMS messages.

EmailMessage -> (string)

The message template for email messages. EmailMessage is allowed only if EmailSendingAccount is DEVELOPER.

EmailSubject -> (string)

The subject line for email messages. EmailSubject is allowed only if EmailSendingAccount is DEVELOPER.

UserPoolAddOns -> (structure)

User pool add-ons. Contains settings for activation of advanced security features. To log user security information but take no action, set to AUDIT . To configure automatic security responses to risky traffic to your user pool, set to ENFORCED .

For more information, see Adding advanced security to a user pool .

AdvancedSecurityMode -> (string)

The operating mode of advanced security features for standard authentication types in your user pool, including username-password and secure remote password (SRP) authentication.

AdvancedSecurityAdditionalFlows -> (structure)

Advanced security configuration options for additional authentication types in your user pool, including custom authentication.

CustomAuthMode -> (string)

The operating mode of advanced security features in custom authentication with Custom authentication challenge Lambda triggers .

UsernameConfiguration -> (structure)

Case sensitivity of the username input for the selected sign-in option. When case sensitivity is set to False (case insensitive), users can sign in with any combination of capital and lowercase letters. For example, username , USERNAME , or UserName , or for email, email@example.com or EMaiL@eXamplE.Com . For most use cases, set case sensitivity to False (case insensitive) as a best practice. When usernames and email addresses are case insensitive, Amazon Cognito treats any variation in case as the same user, and prevents a case variation from being assigned to the same attribute for a different user.

This configuration is immutable after you set it. For more information, see UsernameConfigurationType .

CaseSensitive -> (boolean)

Specifies whether user name case sensitivity will be applied for all users in the user pool through Amazon Cognito APIs. For most use cases, set case sensitivity to False (case insensitive) as a best practice. When usernames and email addresses are case insensitive, users can sign in as the same user when they enter a different capitalization of their user name.

Valid values include:

true

Enables case sensitivity for all username input. When this option is set to true , users must sign in using the exact capitalization of their given username, such as “UserName”. This is the default value.

false

Enables case insensitivity for all username input. For example, when this option is set to false , users can sign in using username , USERNAME , or UserName . This option also enables both preferred_username and email alias to be case insensitive, in addition to the username attribute.

Arn -> (string)

The Amazon Resource Name (ARN) of the user pool.

AccountRecoverySetting -> (structure)

The available verified method a user can use to recover their password when they call ForgotPassword . You can use this setting to define a preferred method when a user has more than one method available. With this setting, SMS doesn't qualify for a valid password recovery mechanism if the user also has SMS multi-factor authentication (MFA) activated. In the absence of this setting, Amazon Cognito uses the legacy behavior to determine the recovery method where SMS is preferred through email.

RecoveryMechanisms -> (list)

The list of options and priorities for user message delivery in forgot-password operations. Sets or displays user pool preferences for email or SMS message priority, whether users should fall back to a second delivery method, and whether passwords should only be reset by administrators.

(structure)

A recovery option for a user. The AccountRecoverySettingType data type is an array of this object. Each RecoveryOptionType has a priority property that determines whether it is a primary or secondary option.

For example, if verified_email has a priority of 1 and verified_phone_number has a priority of 2 , your user pool sends account-recovery messages to a verified email address but falls back to an SMS message if the user has a verified phone number. The admin_only option prevents self-service account recovery.

This data type is a request and response parameter of CreateUserPool and UpdateUserPool , and a response parameter of DescribeUserPool .

Priority -> (integer)

Your priority preference for using the specified attribute in account recovery. The highest priority is 1 .

Name -> (string)

The recovery method that this object sets a recovery option for.

UserPoolTier -> (string)

The user pool feature plan , or tier. This parameter determines the eligibility of the user pool for features like managed login, access-token customization, and threat protection. Defaults to ESSENTIALS .
