Amazon Cognito User Pools Add AWS PrivateLink Support
🔒 Amazon Cognito user pools now support AWS PrivateLink, enabling private VPC connectivity to manage and authenticate against user pools without traversing the public internet. The enhancement covers user pool management APIs, administrative operations, and sign-in for local Cognito users, but does not support OAuth 2.0 authorization code flow (hosted UI/social logins), client credentials, or federated SAML/OIDC sign-ins via VPC endpoints. It is available in all Regions where Cognito user pools exist except AWS GovCloud (US); creating VPC endpoints will incur AWS PrivateLink charges.
