  • Method Details

    • challengeName

      public final ChallengeNameType challengeName()

      The name of an additional authentication challenge that you must respond to.

      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.

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

      • PASSWORD: Respond with USER_PASSWORD_AUTH parameters: USERNAME (required), PASSWORD (required), SECRET_HASH (required if the app client is configured with a client secret), DEVICE_KEY.

      • PASSWORD_SRP: Respond with USER_SRP_AUTH parameters: USERNAME (required), SRP_A (required), SECRET_HASH (required if the app client is configured with a client secret), DEVICE_KEY.

      • SELECT_CHALLENGE: Respond to the challenge with USERNAME and an ANSWER that matches one of the challenge types in the AvailableChallenges response parameter.

      • SMS_MFA: Respond with an SMS_MFA_CODE that your user pool delivered in an SMS message.

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

      • PASSWORD_VERIFIER: Respond with PASSWORD_CLAIM_SIGNATURE, PASSWORD_CLAIM_SECRET_BLOCK, and TIMESTAMP after client-side SRP calculations.

      • 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.

      • 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.

      If the service returns an enum value that is not available in the current SDK version, challengeName will return ChallengeNameType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from challengeNameAsString().

      Returns:

      See Also:

    • session

      public final String session()

      The session identifier that links a challenge response to the initial authentication request. If the user must pass another challenge, Amazon Cognito returns a session ID and challenge parameters.

      Returns:
      The session identifier that links a challenge response to the initial authentication request. If the user must pass another challenge, Amazon Cognito returns a session ID and challenge parameters.

    • hasChallengeParameters

      public final boolean hasChallengeParameters()
      For responses, this returns true if the service returned a value for the ChallengeParameters property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • challengeParameters

      public final Map<String,String> challengeParameters()

      The required parameters of the ChallengeName challenge.

      All challenges require USERNAME. They also require SECRET_HASH if your app client has a client secret.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasChallengeParameters() method.

      Returns:
      The required parameters of the ChallengeName challenge.

      All challenges require USERNAME. They also require SECRET_HASH if your app client has a client secret.

    • authenticationResult

      public final AuthenticationResultType authenticationResult()

      The result of a successful and complete authentication request. This result is only returned if the user doesn't need to pass another challenge. If they must pass another challenge before they get tokens, Amazon Cognito returns a challenge in ChallengeName, ChallengeParameters, and Session response parameters.

      Returns:
      The result of a successful and complete authentication request. This result is only returned if the user doesn't need to pass another challenge. If they must pass another challenge before they get tokens, Amazon Cognito returns a challenge in ChallengeName, ChallengeParameters, and Session response parameters.

    • availableChallenges

      public final List<ChallengeNameType> availableChallenges()

      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.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasAvailableChallenges() method.

      Returns:
      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.

    • hasAvailableChallenges

      public final boolean hasAvailableChallenges()
      For responses, this returns true if the service returned a value for the AvailableChallenges property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • availableChallengesAsStrings

      public final List<String> availableChallengesAsStrings()

      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.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasAvailableChallenges() method.
