Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

EmailMfaConfiguration

Shows configuration for user pool email message MFA and sign-in with one-time passwords (OTPs). Includes the subject and body of the email message template for sign-in and MFA messages. To activate this setting, your user pool must be in the Essentials tier or higher.

Type: EmailMfaConfigType object

MfaConfiguration

Displays the state of multi-factor authentication (MFA) as 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

SmsMfaConfiguration

Shows user pool configuration for SMS message MFA. Includes the message template and the SMS message sending configuration for Amazon SNS.

Type: SmsMfaConfigType object

SoftwareTokenMfaConfiguration

Shows user pool configuration for time-based one-time password (TOTP) MFA. Includes TOTP enabled or disabled state.

Type: SoftwareTokenMfaConfigType object

WebAuthnConfiguration

Shows user pool configuration for sign-in with passkey authenticators like biometric devices and security keys. Passkeys are not eligible MFA factors. They are instead an eligible primary sign-in factor for choice-based authentication, or the USER_AUTH flow.

Type: WebAuthnConfigurationType object
