admin-respond-to-auth-challenge

Description

Responds to an authentication challenge, as an administrator.

Note

This action might generate an SMS text message. Starting June 1, 2021, U.S. telecom carriers require that you register an origination phone number before you can send SMS messages to U.S. phone numbers. If you use SMS text messages in Amazon Cognito, you must register a phone number with Amazon Pinpoint . Cognito will use the the registered number automatically. Otherwise, Cognito users that must receive SMS messages might be unable to sign up, activate their accounts, or sign in.

If you have never used SMS text messages with Amazon Cognito or any other Amazon Web Service, Amazon SNS might place your account in SMS sandbox. In * sandbox mode * , you’ll have limitations, such as sending messages to only verified phone numbers. After testing in the sandbox environment, you can move out of the SMS sandbox and into production. For more information, see SMS message settings for Cognito User Pools in the Amazon Cognito Developer Guide .

Calling this action requires developer credentials.

Options

--user-pool-id (string)

The ID of the Amazon Cognito user pool.

--client-id (string)

The app client ID.

--challenge-name (string)

The challenge name. For more information, see AdminInitiateAuth .

Possible values:

• SMS_MFA

• SOFTWARE_TOKEN_MFA

• SELECT_MFA_TYPE

• MFA_SETUP

• PASSWORD_VERIFIER

• CUSTOM_CHALLENGE

• DEVICE_SRP_AUTH

• DEVICE_PASSWORD_VERIFIER

• ADMIN_NO_SRP_AUTH

• NEW_PASSWORD_REQUIRED

--challenge-responses (map)

The challenge responses. These are inputs corresponding to the value of ChallengeName , for example:

• SMS_MFA : SMS_MFA_CODE , USERNAME , SECRET_HASH (if app client is configured with client secret).

• PASSWORD_VERIFIER : PASSWORD_CLAIM_SIGNATURE , PASSWORD_CLAIM_SECRET_BLOCK , TIMESTAMP , USERNAME , SECRET_HASH (if app client is configured with client secret).

• ADMIN_NO_SRP_AUTH : PASSWORD , USERNAME , SECRET_HASH (if app client is configured with client secret).

• NEW_PASSWORD_REQUIRED : NEW_PASSWORD , any other required attributes, USERNAME , SECRET_HASH (if app client is configured with client secret).

• MFA_SETUP requires USERNAME , plus you need to use the session value returned by VerifySoftwareToken in the Session parameter.

The value of the USERNAME attribute must be the user’s actual username, not an alias (such as email address or phone number). To make this easier, the AdminInitiateAuth response includes the actual username value in the USERNAMEUSER_ID_FOR_SRP attribute, even if you specified an alias in your call to AdminInitiateAuth .

value -> (string)

Shorthand Syntax:

KeyName1=string,KeyName2=string

JSON Syntax:

{"string": "string"
  ...}

--session (string)

The session which should be passed both ways in challenge-response calls to the service. If InitiateAuth or RespondToAuthChallenge 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.

--analytics-metadata (structure)

The analytics metadata for collecting Amazon Pinpoint metrics for AdminRespondToAuthChallenge calls.

AnalyticsEndpointId -> (string)

The endpoint ID.

Shorthand Syntax:

AnalyticsEndpointId=string

JSON Syntax:

{
  "AnalyticsEndpointId": "string"
}

--context-data (structure)

Contextual data such as the user’s device fingerprint, IP address, or location used for evaluating the risk of an unexpected event by Amazon Cognito advanced security.

IpAddress -> (string)

Source IP address of your user.

ServerName -> (string)

Your server endpoint where this API is invoked.

ServerPath -> (string)

Your server path where this API is invoked.

HttpHeaders -> (list)

HttpHeaders received on your server in same order.

(structure)

The HTTP header.

headerName -> (string)

The header name

headerValue -> (string)

The header value.

EncodedData -> (string)

Encoded data containing device fingerprinting details, collected using the Amazon Cognito context data collection library.

Shorthand Syntax:

IpAddress=string,ServerName=string,ServerPath=string,HttpHeaders=[{headerName=string,headerValue=string},{headerName=string,headerValue=string}],EncodedData=string

JSON Syntax:

{
  "IpAddress": "string",
  "ServerName": "string",
  "ServerPath": "string",
  "HttpHeaders": [
    {
      "headerName": "string",
      "headerValue": "string"
    }
    ...
  ],
  "EncodedData": "string"
}

--client-metadata (map)

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 you use the AdminRespondToAuthChallenge API action, Amazon Cognito invokes any functions that are assigned to the following triggers: pre sign-up , custom message , post authentication , user migration , pre token generation , define auth challenge , create auth challenge , and verify auth challenge response . 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, which provides the data that you assigned to the ClientMetadata parameter in your AdminRespondToAuthChallenge request. In your function code in Lambda, you can process the clientMetadata value to enhance your workflow for your specific needs.

For more information, see Customizing User Pool Workflows with Lambda Triggers in the Amazon Cognito Developer Guide .

Note

Take the following limitations into consideration when you use the ClientMetadata parameter:

• Amazon Cognito does not store the ClientMetadata value. This data is available only to Lambda triggers that are assigned to a user pool to support custom workflows. If your user pool configuration does not include triggers, the ClientMetadata parameter serves no purpose.

• Amazon Cognito does not validate the ClientMetadata value.

• Amazon Cognito does not encrypt the the ClientMetadata value, so don’t use it to provide sensitive information.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.
