Class InitiateAuthResponse

    • Method Detail

      • challengeName

        public final ChallengeNameType challengeName()

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

        Valid values include the following:

        All of the following challenges require USERNAME and SECRET_HASH (if applicable) in the parameters.

        • WEB_AUTHN: Respond to the challenge with the results of a successful authentication with a passkey, or webauthN, factor. These are typically biometric devices or 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: Next challenge is to supply an SMS_MFA_CODEthat your user pool delivered in an SMS message.

        • EMAIL_OTP: Next challenge is to supply an EMAIL_OTP_CODE that your user pool delivered in an email message.

        • PASSWORD_VERIFIER: Next challenge is to supply PASSWORD_CLAIM_SIGNATURE, PASSWORD_CLAIM_SECRET_BLOCK, and TIMESTAMP after the 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.

        • DEVICE_SRP_AUTH: If device tracking was activated on your user pool and the previous challenges were passed, this challenge is returned so that Amazon Cognito can start tracking this device.

        • DEVICE_PASSWORD_VERIFIER: Similar to PASSWORD_VERIFIER, but for devices only.

        • 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. For more information, see RespondToAuthChallenge.

          Amazon Cognito only returns this challenge for users who have temporary passwords. Because of this, and because in some cases you can create users who don't have values for required attributes, take care to collect and submit required-attribute values for all users who don't have passwords. You can create a user in the Amazon Cognito console without, for example, a required birthdate attribute. The API response from Amazon Cognito won't prompt you to submit a birthdate for the user if they don't have a password.

          In a NEW_PASSWORD_REQUIRED challenge response, you can't modify a required attribute that already has a value. In RespondToAuthChallenge, set a value for any keys that Amazon Cognito returned in the requiredAttributes parameter, then use the 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 software token MFA, use the session returned here from InitiateAuth as an input to AssociateSoftwareToken. Use the session returned by VerifySoftwareToken as an input to RespondToAuthChallenge with challenge name MFA_SETUP to complete sign-in. To set up SMS MFA, an administrator should help the user to add a phone number to their account, and then the user should call InitiateAuth again to restart sign-in.

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

        Valid values include the following:

        All of the following challenges require USERNAME and SECRET_HASH (if applicable) in the parameters.

        • WEB_AUTHN: Respond to the challenge with the results of a successful authentication with a passkey, or webauthN, factor. These are typically biometric devices or 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: Next challenge is to supply an SMS_MFA_CODEthat your user pool delivered in an SMS message.

        • EMAIL_OTP: Next challenge is to supply an EMAIL_OTP_CODE that your user pool delivered in an email message.

        • PASSWORD_VERIFIER: Next challenge is to supply PASSWORD_CLAIM_SIGNATURE, PASSWORD_CLAIM_SECRET_BLOCK, and TIMESTAMP after the 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.

      • session

        public final String session()

        The session that should pass both ways in challenge-response calls to the service. If the caller must pass another challenge, they return a session with other challenge parameters. Include this session identifier in a RespondToAuthChallenge API request.

        Returns:
        The session that should pass both ways in challenge-response calls to the service. If the caller must pass another challenge, they return a session with other challenge parameters. Include this session identifier in a RespondToAuthChallenge API request.
      • 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 challenge parameters. These are returned in the InitiateAuth response if you must pass another challenge. The responses in this parameter should be used to compute inputs to the next call ( RespondToAuthChallenge).

        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 challenge parameters. These are returned in the InitiateAuth response if you must pass another challenge. The responses in this parameter should be used to compute inputs to the next call ( RespondToAuthChallenge).

        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 the authentication response. This result is only returned if the caller doesn't need to pass another challenge. If the caller does need to pass another challenge before it gets tokens, ChallengeName, ChallengeParameters, and Session are returned.

        Returns:
        The result of the authentication response. This result is only returned if the caller doesn't need to pass another challenge. If the caller does need to pass another challenge before it gets tokens, ChallengeName, ChallengeParameters, and Session are returned.
      • availableChallenges

        public final List<ChallengeNameType> availableChallenges()

        This response parameter prompts a user to select from multiple available challenges that they can complete authentication with. For example, they might be able to continue with passwordless authentication or with a one-time password from an SMS message.

        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 prompts a user to select from multiple available challenges that they can complete authentication with. For example, they might be able to continue with passwordless authentication or with a one-time password from an SMS message.
      • 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 prompts a user to select from multiple available challenges that they can complete authentication with. For example, they might be able to continue with passwordless authentication or with a one-time password from an SMS message.

        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.
