AWS SDK Version 3 for .NET
API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

Container for the parameters to the ForgotPassword operation. Sends a password-reset confirmation code for the currently signed-in user.

For the Username parameter, you can use the username or user alias.

If neither a verified phone number nor a verified email exists, Amazon Cognito responds with an InvalidParameterException error . If your app client has a client secret and you don't provide a SECRET_HASH parameter, this API returns NotAuthorizedException.

Amazon Cognito doesn't evaluate Identity and Access Management (IAM) policies in requests for this API operation. For this operation, you can't use IAM credentials to authorize requests, and you can't grant IAM permissions in policies. For more information about authorization models in Amazon Cognito, see Using the Amazon Cognito user pools API and user pool endpoints.

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 Services 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.

Constructors

NameDescription
Public Method ForgotPasswordRequest()

Properties

NameTypeDescription
Public Property AnalyticsMetadata Amazon.CognitoIdentityProvider.Model.AnalyticsMetadataType

Gets and sets the property AnalyticsMetadata.

Information that supports analytics outcomes with Amazon Pinpoint, including the user's endpoint ID. The endpoint ID is a destination for Amazon Pinpoint push notifications, for example a device identifier, email address, or phone number.

Public Property ClientId System.String

Gets and sets the property ClientId.

The ID of the user pool app client associated with the current signed-in user.

Public Property ClientMetadata System.Collections.Generic.Dictionary<System.String, System.String>

Gets and sets the property ClientMetadata.

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 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 Lambda, you can process the clientMetadata value to enhance your workflow for your specific needs.

For more information, see Using 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 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 send sensitive information in this parameter.

Public Property SecretHash System.String

Gets and sets the property SecretHash.

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. For more information about SecretHash, see Computing secret hash values.

Public Property UserContextData Amazon.CognitoIdentityProvider.Model.UserContextDataType

Gets and sets the property UserContextData.

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.

Public Property Username System.String

Gets and sets the property Username.

The name of the user that you want to query or modify. The value of this parameter is typically your user's username, but it can be any of their alias attributes. If username isn't an alias attribute in your user pool, this value must be the sub of a local user or the username of a user from a third-party IdP.
