Amazon Cognito User Pools service now supports case insensitivity for user aliases

Posted on: Feb 12, 2020

Amazon Cognito User Pools now enables customers to configure case sensitivity settings for user aliases, including native username, email alias and preferred username alias. With this update, new user pools will be set to case insensitive by default and customers can change the configuration to case sensitive in the console before a user pool is created. Existing user pools will remain as case sensitive. When creating a user pool through Cognito APIs, the user pool will be case sensitive by default. We will change the default setting for the API in the future after a customer notification campaign.

Amazon Cognito User Pools provide a secure user directory that scales to millions of users. As a fully managed service, User Pools provide an identity and authentication layer to applications.

Alias case insensitivity is available in all regions where Amazon Cognito operates. For a list of regions where Amazon Cognito is available, see the AWS Region table. To learn more about Amazon Cognito, visit the documentation. To get started, visit the Amazon Cognito home page.
