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. If a
verified phone number exists for the user, the confirmation code is sent
to the phone number. Otherwise, if a verified email exists, the
confirmation code is sent to the email. If neither a verified phone
number nor a verified email exists, InvalidParameterException is
thrown. To use the confirmation code for resetting the password, call .
cognitoidentityprovider_forgot_password(ClientId, SecretHash,
UserContextData, Username, AnalyticsMetadata, ClientMetadata)[required] The ID of the client associated with the user pool.
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.
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.
[required] The user name of the user for whom you want to enter a code to reset a forgotten password.
The Amazon Pinpoint analytics metadata for collecting metrics for
ForgotPassword calls.
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.
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.
