challenge_name
instance-attribute
¶
challenge_name: ChallengeNameType
The name of the challenge that you are responding to.
You can't respond to an ADMIN_NO_SRP_AUTH challenge with this operation.
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, asCREDENTIAL. Examples of WebAuthn authenticators include biometric devices and security keys. -
PASSWORD: Respond with the user's password asPASSWORD. -
PASSWORD_SRP: Respond with the initial SRP secret asSRP_A. -
SELECT_CHALLENGE: Respond with a challenge selection asANSWER. It must be one of the challenge types in theAvailableChallengesresponse parameter. Add the parameters of the selected challenge, for exampleUSERNAMEandSMS_OTP. -
SMS_MFA: Respond with the code that your user pool delivered in an SMS message, asSMS_MFA_CODE -
EMAIL_MFA: Respond with the code that your user pool delivered in an email message, asEMAIL_MFA_CODE -
EMAIL_OTP: Respond with the code that your user pool delivered in an email message, asEMAIL_OTP_CODE. -
SMS_OTP: Respond with the code that your user pool delivered in an SMS message, asSMS_OTP_CODE. -
PASSWORD_VERIFIER: Respond with the second stage of SRP secrets asPASSWORD_CLAIM_SIGNATURE,PASSWORD_CLAIM_SECRET_BLOCK, andTIMESTAMP. -
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 theChallengeParametersof 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 withPASSWORD_CLAIM_SIGNATURE,PASSWORD_CLAIM_SECRET_BLOCK, andTIMESTAMPafter 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 withNEW_PASSWORDand any required attributes that Amazon Cognito returned in therequiredAttributesparameter. 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_REQUIREDchallenge response, you can't modify a required attribute that already has a value. InAdminRespondToAuthChallengeorRespondToAuthChallenge, set a value for any keys that Amazon Cognito returned in therequiredAttributesparameter, then use theAdminUpdateUserAttributesorUpdateUserAttributesAPI 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 parametersMFAS_CAN_SETUPvalue.To set up time-based one-time password (TOTP) MFA, use the session returned in this challenge from
InitiateAuthorAdminInitiateAuthas an input toAssociateSoftwareToken. Then, use the session returned byVerifySoftwareTokenas an input toRespondToAuthChallengeorAdminRespondToAuthChallengewith challenge nameMFA_SETUPto complete sign-in.To set up SMS or email MFA, collect a
phone_numberoremailattribute for the user. Then restart the authentication flow with anInitiateAuthorAdminInitiateAuthrequest.
challenge_responses
instance-attribute
¶
challenge_responses: NotRequired[ChallengeResponsesType]
The responses to the challenge that you received in the previous request. Each challenge has its own required response parameters. The following examples are partial JSON request bodies that highlight challenge-response parameters.
You must provide a SECRET_HASH parameter in all challenge responses to an app client that has a client secret. Include a DEVICE_KEY for device authentication.
- SELECT_CHALLENGE
-
"ChallengeName": "SELECT_CHALLENGE", "ChallengeResponses": { "USERNAME": "[username]", "ANSWER": "[Challenge name]"}Available challenges are
PASSWORD,PASSWORD_SRP,EMAIL_OTP,SMS_OTP, andWEB_AUTHN.Complete authentication in the

This challenge response is part of the SRP flow. Amazon Cognito requires that your application respond to this challenge within a few seconds. When the response time exceeds this period, your user pool returns a
NotAuthorizedExceptionerror."ChallengeName": "PASSWORD_VERIFIER", "ChallengeResponses": {"PASSWORD_CLAIM_SIGNATURE": "[claim_signature]", "PASSWORD_CLAIM_SECRET_BLOCK": "[secret_block]", "TIMESTAMP": [timestamp], "USERNAME": "[username]"} - CUSTOM_CHALLENGE

NEW_PASSWORD_REQUIREDchallenge response, you can't modify a required attribute that already has a value. InAdminRespondToAuthChallengeorRespondToAuthChallenge, set a value for any keys that Amazon Cognito returned in therequiredAttributesparameter, then use theAdminUpdateUserAttributesorUpdateUserAttributesAPI operation to modify the value of any additional attributes. - SOFTWARE_TOKEN_MFA

client_id
instance-attribute
¶
client_id: ClientIdType
The ID of the app client where the user is signing in.
client_metadata
instance-attribute
¶
client_metadata: NotRequired[ClientMetadataType]
A map of custom key-value pairs that you can provide as input for any custom workflows that this action triggers. You create custom workflows by assigning Lambda functions to user pool triggers.
When Amazon Cognito invokes any of these functions, it passes a JSON payload, which the function receives as input. This payload contains a clientMetadata attribute that provides the data that you assigned to the ClientMetadata parameter in your request. In your function code, you can process the clientMetadata value to enhance your workflow for your specific needs.
To review the Lambda trigger types that Amazon Cognito invokes at runtime with API requests, see Connecting API actions to Lambda triggers in the Amazon Cognito Developer Guide.
When you use the ClientMetadata parameter, note that Amazon Cognito won't do the following:
-
Store the
ClientMetadatavalue. This data is available only to Lambda triggers that are assigned to a user pool to support custom workflows. If your user pool configuration doesn't include triggers, theClientMetadataparameter serves no purpose. -
Validate the
ClientMetadatavalue. -
Encrypt the
ClientMetadatavalue. Don't send sensitive information in this parameter.
session
instance-attribute
¶
session: NotRequired[SessionType]
The session identifier that maintains the state of authentication requests and challenge responses. If an AdminInitiateAuth or AdminRespondToAuthChallenge API request results in a determination that your application must pass another challenge, Amazon Cognito returns a session with other challenge parameters. Send this session identifier, unmodified, to the next AdminRespondToAuthChallenge request.
user_context_data
instance-attribute
¶
user_context_data: NotRequired[UserContextDataType]
Contextual data about your user session like the device fingerprint, IP address, or location. Amazon Cognito threat protection evaluates the risk of an authentication event based on the context that your app generates and passes to Amazon Cognito when it makes API requests.
For more information, see Collecting data for threat protection in applications.
