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, US telecom carriers require you to register an origination phone number before you can send SMS messages to US phone numbers. If you use SMS text messages in Amazon Cognito, you must register a phone number with Amazon Pinpoint . Amazon Cognito uses the registered number automatically. Otherwise, Amazon Cognito users who must receive SMS messages might not be able 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 Simple Notification Service might place your account in the SMS sandbox. In * sandbox mode * , you can send messages only to verified phone numbers. After you test your app while in the sandbox environment, you can move out of the sandbox and into production. For more information, see SMS message settings for Amazon 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).

Note

PASSWORD_VERIFIER requires DEVICE_KEY when signing in with a remembered device.

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

NEW_PASSWORD_REQUIRED : NEW_PASSWORD , USERNAME , SECRET_HASH (if app client is configured with client secret). To set any required attributes that Amazon Cognito returned as requiredAttributes in the AdminInitiateAuth response, add a ``userAttributes.*attributename* `` parameter. This parameter can also set values for writable attributes that aren’t required by your user pool.

Note

In a NEW_PASSWORD_REQUIRED challenge response, you can’t modify a required attribute that already has a value. In AdminRespondToAuthChallenge , set a value for any keys that Amazon Cognito returned in the requiredAttributes parameter, then use the AdminUpdateUserAttributes API operation to modify the value of any additional attributes.

MFA_SETUP requires USERNAME , plus you must 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 an email address or phone number). To make this simpler, the AdminInitiateAuth response includes the actual username value in the USERNAMEUSER_ID_FOR_SRP attribute. This happens even if you specified an alias in your call to AdminInitiateAuth .

key -> (string)

value -> (string)

Shorthand Syntax:

KeyName1=string,KeyName2=string

JSON Syntax:

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

--session (string)

The session that should be passed both ways in challenge-response calls to the service. If an InitiateAuth or RespondToAuthChallenge API call determines that the caller must pass another challenge, it returns 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 about your user session, such as the device fingerprint, IP address, or location. Amazon Cognito advanced security 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.

IpAddress -> (string)

The source IP address of your user’s device.

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 device-fingerprint details that your app collected with the Amazon Cognito context data collection library. For more information, see Adding user device and session data to API requests .

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 you have assigned to the following triggers:

pre sign-up

custom message

post authentication

user migration

pre token generation

define auth challenge

create auth challenge

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 that 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

When you use the ClientMetadata parameter, remember that Amazon Cognito won’t do the following:

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 doesn’t include triggers, the ClientMetadata parameter serves no purpose.

Validate the ClientMetadata value.

Encrypt the ClientMetadata value. Don’t use Amazon Cognito to provide sensitive information.

key -> (string)

value -> (string)

Shorthand Syntax:

KeyName1=string,KeyName2=string

JSON Syntax:

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

--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.
