[ aws . cognito-idp ]

forgot-password

Description

Calling this API causes a message to be sent to the end user with a confirmation code that is required to change the user's password. For the Username parameter, you can use the username or user alias. The method used to send the confirmation code is sent according to the specified AccountRecoverySetting. For more information, see Recovering User Accounts in the Amazon Cognito Developer Guide . If neither a verified phone number nor a verified email exists, an InvalidParameterException is thrown. To use the confirmation code for resetting the password, call ConfirmForgotPassword .

Synopsis

  forgot-password
--client-id <value>
[--secret-hash <value>]
[--user-context-data <value>]
--username <value>
[--analytics-metadata <value>]
[--client-metadata <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--client-id (string)

The ID of the client associated with the user pool.

--secret-hash (string)

A keyed-hash message authentication code (HMAC) calculated using the secret key of a user pool client and username plus the client ID in the message.

--user-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.

EncodedData -> (string)

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.

Shorthand Syntax:

EncodedData=string

JSON Syntax:

{
  "EncodedData": "string"
}

--username (string)

The user name of the user for whom you want to enter a code to reset a forgotten password.

--analytics-metadata (structure)

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

AnalyticsEndpointId -> (string)

The endpoint ID.

Shorthand Syntax:

AnalyticsEndpointId=string

JSON Syntax:

{
  "AnalyticsEndpointId": "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 AWS Lambda functions to user pool triggers. When you use the ForgotPassword API action, Amazon Cognito invokes any functions that are assigned to the following triggers: pre sign-up , custom message , and user migration . 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 ForgotPassword request. In your function code in AWS 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 AWS 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.

key -> (string)

value -> (string)

Shorthand Syntax:

KeyName1=string,KeyName2=string

JSON Syntax:

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

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. 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.

Examples

To force a password change

The following forgot-password example sends a message to jane@example.com to change their password.

aws cognito-idp forgot-password --client-id 38fjsnc484p94kpqsnet7mpld0 --username jane@example.com

Output:

{
    "CodeDeliveryDetails": {
        "Destination": "j***@e***.com",
        "DeliveryMedium": "EMAIL",
        "AttributeName": "email"
    }
}

Output

CodeDeliveryDetails -> (structure)

The code delivery details returned by the server in response to the request to reset a password.

Destination -> (string)

The destination for the code delivery details.

DeliveryMedium -> (string)

The delivery medium (email message or phone number).

AttributeName -> (string)

The attribute name.
