<p>Resets the specified user's password in a user pool as an administrator. Works on any user.</p> <p>When a developer calls this API, the current password is invalidated, so it must be changed. If a user tries to sign in after the API is called, the app will get a PasswordResetRequiredException exception back and should direct the user down the flow to reset the password, which is the same as the forgot password flow. In addition, if the user pool has phone verification selected and a verified phone number exists for the user, or if email verification is selected and a verified email exists for the user, calling this API will also result in sending a message to the end user with the code to change their password.</p> <note> <p>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 <a href="https://console.aws.amazon.com/pinpoint/home/">Amazon Pinpoint</a>. 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.</p> <p>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 <i> <a href="https://docs.aws.amazon.com/sns/latest/dg/sns-sms-sandbox.html">sandbox mode</a> </i>, 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 <a href="https://docs.aws.amazon.com/cognito/latest/developerguide/cognito-user-identity-pools-sms-userpool-settings.html"> SMS message settings for Amazon Cognito user pools</a> in the <i>Amazon Cognito Developer Guide</i>.</p> </note> <p>Calling this action requires developer credentials.</p>
