Resends the confirmation (for confirmation of registration) to a specific user in the user pool.
This action might generate an SMS text message. Starting June 1, 2021, U.S. telecom carriers require that you register an origination phone number before you can send SMS messages to U.S. phone numbers. If you use SMS text messages in Amazon Cognito, you must register a phone number with Amazon Pinpoint
. Cognito will use the the registered number automatically. Otherwise, Cognito users that must receive SMS messages might be unable 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 SNS might place your account in SMS sandbox. In sandbox mode
, you’ll have limitations, such as sending messages to only verified phone numbers. After testing in the sandbox environment, you can move out of the SMS sandbox and into production. For more information, see SMS message settings for Cognito User Pools
