AWSCognitoIdentityProviderInitiateAuthResponse

@interface AWSCognitoIdentityProviderInitiateAuthResponse

Initiates the authentication response.

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

    Declaration

    Objective-C

    @property (readwrite, strong, nonatomic)
    AWSCognitoIdentityProviderAuthenticationResultType
        *_Nullable authenticationResult;

    Swift

    var authenticationResult: AWSCognitoIdentityProviderAuthenticationResultType? { get set }

  • The name of the challenge which you are responding to with this call. This is returned to you in the AdminInitiateAuth response if you need to pass another challenge.

    Valid values include the following. Note that all of these challenges require USERNAME and SECRET_HASH (if applicable) in the parameters.

    • SMS_MFA: Next challenge is to supply an SMS_MFA_CODE, delivered via SMS.

    • 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 enabled 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 which are required to change their passwords after successful first login. This challenge should be passed with NEW_PASSWORD and any other required attributes.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic)
    AWSCognitoIdentityProviderChallengeNameType challengeName;

    Swift

    var challengeName: AWSCognitoIdentityProviderChallengeNameType { get set }

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

    All challenges require USERNAME and SECRET_HASH (if applicable).

    Declaration

    Objective-C

    @property (readwrite, strong, nonatomic)
    NSDictionary<NSString *, NSString *> *_Nullable challengeParameters;

    Swift

    var challengeParameters: [String : String]? { get set }

  • The session which should be passed both ways in challenge-response calls to the service. If the or API call determines that the caller needs to go through another challenge, they return a session with other challenge parameters. This session should be passed as it is to the next RespondToAuthChallenge API call.

    Declaration

    Objective-C

    @property (readwrite, strong, nonatomic) NSString *_Nullable session;

    Swift

    var session: String? { get set }
