CreateUserPool - Amazon Cognito User Pools

CreateUserPool

Creates a new Amazon Cognito user pool. This operation sets basic and advanced configuration options.

You can create a user pool in the Amazon Cognito console to your preferences and use the output of DescribeUserPool to generate requests from that baseline.

Important

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

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 AWS 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.

Note

Amazon Cognito evaluates AWS 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.

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

AccountRecoverySetting

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. Email MFA is also disqualifying for account recovery with email. In the absence of this setting, Amazon Cognito uses the legacy behavior to determine the recovery method where SMS is preferred over email.

As a best practice, configure both verified_email and verified_phone_number, with one having a higher priority than the other.

Type: AccountRecoverySettingType object

Required: No

AdminCreateUserConfig

The configuration for administrative creation of users. Includes the template for the invitation message for new users, the duration of temporary passwords, and permitting self-service sign-up.

Type: AdminCreateUserConfigType object

Required: No

AliasAttributes

Attributes supported as an alias for this user pool. For more information about alias attributes, see Customizing sign-in attributes.

Type: Array of strings

Valid Values: phone_number | email | preferred_username

Required: No

AutoVerifiedAttributes

The attributes that you want your user pool to automatically verify. For more information, see Verifying contact information at sign-up.

Type: Array of strings

Valid Values: phone_number | email

Required: No

DeletionProtection

When active, DeletionProtection prevents accidental deletion of your user pool. Before you can delete a user pool that you have protected against deletion, you must deactivate this feature.

When you try to delete a protected user pool in a DeleteUserPool API request, Amazon Cognito returns an InvalidParameterException error. To delete a protected user pool, send a new DeleteUserPool request after you deactivate deletion protection in an UpdateUserPool API request.

Type: String

Valid Values: ACTIVE | INACTIVE

Required: No

DeviceConfiguration

The device-remembering configuration for a user pool. Device remembering or device tracking is a "Remember me on this device" option for user pools that perform authentication with the device key of a trusted device in the back end, instead of a user-provided MFA code. For more information about device authentication, see Working with user devices in your 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. For more infor

Type: DeviceConfigurationType object

Required: No

EmailConfiguration

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

Type: EmailConfigurationType object

Required: No

EmailVerificationMessage

This parameter is no longer used. See VerificationMessageTemplateType.

Type: String

Length Constraints: Minimum length of 6. Maximum length of 20000.

Pattern: [\p{L}\p{M}\p{S}\p{N}\p{P}\s*]*\{####\}[\p{L}\p{M}\p{S}\p{N}\p{P}\s*]*

Required: No

EmailVerificationSubject

This parameter is no longer used. See VerificationMessageTemplateType.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 140.

Pattern: [\p{L}\p{M}\p{S}\p{N}\p{P}\s]+

Required: No

LambdaConfig

A collection of user pool Lambda triggers. Amazon Cognito invokes triggers at several possible stages of authentication operations. Triggers can modify the outcome of the operations that invoked them.

Type: LambdaConfigType object

Required: No

MfaConfiguration

Sets multi-factor authentication (MFA) to be on, off, or optional. When ON, all users must set up MFA before they can sign in. When OPTIONAL, your application must make a client-side determination of whether a user wants to register an MFA device. For user pools with adaptive authentication with threat protection, choose OPTIONAL.

When MfaConfiguration is OPTIONAL, managed login doesn't automatically prompt users to set up MFA. Amazon Cognito generates MFA prompts in API responses and in managed login for users who have chosen and configured a preferred MFA factor.

Type: String

Valid Values: OFF | ON | OPTIONAL

Required: No

Policies

The password policy and sign-in policy in the user pool. The password policy sets options like password complexity requirements and password history. The sign-in policy sets the options available to applications in choice-based authentication.

Type: UserPoolPolicyType object

Required: No

PoolName

A friendly name for your user pool.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 128.

Pattern: [\w\s+=,.@-]+

Required: Yes

Schema

An array of attributes for the new user pool. You can add custom attributes and modify the properties of default attributes. The specifications in this parameter set the required attributes in your user pool. For more information, see Working with user attributes.

Array Members: Minimum number of 1 item. Maximum number of 50 items.

Required: No

SmsAuthenticationMessage

The contents of the SMS message that your user pool sends to users in SMS OTP and MFA authentication.

Type: String

Length Constraints: Minimum length of 6. Maximum length of 140.

Pattern: .*\{####\}.*

Required: No

SmsConfiguration

The settings for your Amazon Cognito user pool to send SMS messages with Amazon Simple Notification Service. To send SMS messages with Amazon SNS in the AWS Region that you want, the Amazon Cognito user pool uses an AWS Identity and Access Management (IAM) role in your AWS account. For more information see SMS message settings.

Type: SmsConfigurationType object

Required: No

SmsVerificationMessage

This parameter is no longer used. See VerificationMessageTemplateType.

Type: String

Length Constraints: Minimum length of 6. Maximum length of 140.

Pattern: .*\{####\}.*

Required: No

UserAttributeUpdateSettings

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.

Type: UserAttributeUpdateSettingsType object

Required: No

UsernameAttributes

Specifies whether a user can use an email address or phone number as a username when they sign up. For more information, see Customizing sign-in attributes.

Type: Array of strings

Valid Values: phone_number | email

Required: No

UsernameConfiguration

Sets the case sensitivity option for sign-in usernames. When CaseSensitive is 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 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.

When CaseSensitive is true (case sensitive), Amazon Cognito interprets USERNAME and UserName as distinct users.

This configuration is immutable after you set it.

Type: UsernameConfigurationType object

Required: No

UserPoolAddOns

Contains settings for activation of threat protection, including the operating mode and additional authentication types. To log user security information but take no action, set to AUDIT. To configure automatic security responses to potentially unwanted traffic to your user pool, set to ENFORCED.

For more information, see Adding advanced security to a user pool. To activate this setting, your user pool must be on the Plus tier.

Type: UserPoolAddOnsType object

Required: No

UserPoolTags

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.

Type: String to string map

Key Length Constraints: Minimum length of 1. Maximum length of 128.

Value Length Constraints: Minimum length of 0. Maximum length of 256.

Required: No

UserPoolTier

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.

Type: String

Valid Values: LITE | ESSENTIALS | PLUS

Required: No

VerificationMessageTemplate

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

Set the email message type that corresponds to your DefaultEmailOption selection. For CONFIRM_WITH_LINK, specify an EmailMessageByLink and leave EmailMessage blank. For CONFIRM_WITH_CODE, specify an EmailMessage and leave EmailMessageByLink blank. When you supply both parameters with either choice, Amazon Cognito returns an error.

Type: VerificationMessageTemplateType object

Required: No
