CONSTRUCTOR

IMPORTING

Optional arguments:

iv_challengename TYPE /AWS1/CGPCHALLENGENAMETYPE /AWS1/CGPCHALLENGENAMETYPE

The name of the challenge that you're responding to with this call. This is returned in the AdminInitiateAuth response if you must pass another challenge.

Possible challenges include the following:

All of the following challenges require USERNAME and, when the app client has a client secret, SECRET_HASH in the parameters. Include a DEVICE_KEY for device authentication.

  • WEB_AUTHN: Respond to the challenge with the results of a successful authentication with a WebAuthn authenticator, or passkey, as CREDENTIAL. Examples of WebAuthn authenticators include biometric devices and security keys.

  • PASSWORD: Respond with the user's password as PASSWORD.

  • PASSWORD_SRP: Respond with the initial SRP secret as SRP_A.

  • SELECT_CHALLENGE: Respond with a challenge selection as ANSWER. It must be one of the challenge types in the AvailableChallenges response parameter. Add the parameters of the selected challenge, for example USERNAME and SMS_OTP.

  • SMS_MFA: Respond with the code that your user pool delivered in an SMS message, as SMS_MFA_CODE

  • EMAIL_MFA: Respond with the code that your user pool delivered in an email message, as EMAIL_MFA_CODE

  • EMAIL_OTP: Respond with the code that your user pool delivered in an email message, as EMAIL_OTP_CODE .

  • SMS_OTP: Respond with the code that your user pool delivered in an SMS message, as SMS_OTP_CODE.

  • PASSWORD_VERIFIER: Respond with the second stage of SRP secrets as PASSWORD_CLAIM_SIGNATURE, PASSWORD_CLAIM_SECRET_BLOCK, and TIMESTAMP.

  • CUSTOM_CHALLENGE: This is returned if your custom authentication flow determines that the user should pass another challenge before tokens are issued. The parameters of the challenge are determined by your Lambda function and issued in the ChallengeParameters of a challenge response.

  • DEVICE_SRP_AUTH: Respond with the initial parameters of device SRP authentication. For more information, see Signing in with a device.

  • DEVICE_PASSWORD_VERIFIER: Respond with PASSWORD_CLAIM_SIGNATURE, PASSWORD_CLAIM_SECRET_BLOCK, and TIMESTAMP after client-side SRP calculations. For more information, see Signing in with a device.

  • NEW_PASSWORD_REQUIRED: For users who are required to change their passwords after successful first login. Respond to this challenge with NEW_PASSWORD and any required attributes that Amazon Cognito returned in the requiredAttributes parameter. You can also set values for attributes that aren't required by your user pool and that your app client can write.

    Amazon Cognito only returns this challenge for users who have temporary passwords. When you create passwordless users, you must provide values for all required attributes.

    In a NEW_PASSWORD_REQUIRED challenge response, you can't modify a required attribute that already has a value. In AdminRespondToAuthChallenge or RespondToAuthChallenge, set a value for any keys that Amazon Cognito returned in the requiredAttributes parameter, then use the AdminUpdateUserAttributes or UpdateUserAttributes API operation to modify the value of any additional attributes.

  • MFA_SETUP: For users who are required to setup an MFA factor before they can sign in. The MFA types activated for the user pool will be listed in the challenge parameters MFAS_CAN_SETUP value.

    To set up time-based one-time password (TOTP) MFA, use the session returned in this challenge from InitiateAuth or AdminInitiateAuth as an input to AssociateSoftwareToken. Then, use the session returned by VerifySoftwareToken as an input to RespondToAuthChallenge or AdminRespondToAuthChallenge with challenge name MFA_SETUP to complete sign-in.

    To set up SMS or email MFA, collect a phone_number or email attribute for the user. Then restart the authentication flow with an InitiateAuth or AdminInitiateAuth request.

iv_session TYPE /AWS1/CGPSESSIONTYPE /AWS1/CGPSESSIONTYPE

The session that must be passed to challenge-response requests. If an AdminInitiateAuth or AdminRespondToAuthChallenge API request results in another authentication challenge, Amazon Cognito returns a session ID and the parameters of the next challenge. Pass this session ID in the Session parameter of AdminRespondToAuthChallenge.

it_challengeparameters TYPE /AWS1/CL_CGPCHALLENGEPRMSTYP00=>TT_CHALLENGEPARAMETERSTYPE TT_CHALLENGEPARAMETERSTYPE

The parameters of an authentication challenge. Amazon Cognito returns challenge parameters as a guide to the responses your user or application must provide for the returned ChallengeName. Calculate responses to the challenge parameters and pass them in the ChallengeParameters of AdminRespondToAuthChallenge.

All challenges require USERNAME and, when the app client has a client secret, SECRET_HASH.

In SRP challenges, Amazon Cognito returns the username attribute in USER_ID_FOR_SRP instead of any email address, preferred username, or phone number alias that you might have specified in your AdminInitiateAuth request. You must use the username and not an alias in the ChallengeResponses of your challenge response.

io_authenticationresult TYPE REF TO /AWS1/CL_CGPAUTHNTCTNRSLTTYPE /AWS1/CL_CGPAUTHNTCTNRSLTTYPE

The outcome of successful authentication. This is only returned if the user pool has no additional challenges to return. If Amazon Cognito returns another challenge, the response includes ChallengeName, ChallengeParameters, and Session so that your user can answer the challenge.

it_availablechallenges TYPE /AWS1/CL_CGPAVAILABLECHALLEN00=>TT_AVAILABLECHALLENGELISTTYPE TT_AVAILABLECHALLENGELISTTYPE

This response parameter lists the available authentication challenges that users can select from in choice-based authentication. For example, they might be able to choose between passkey authentication, a one-time password from an SMS message, and a traditional password.
