Amazon Cognito identity pools now support private connectivity with AWS PrivateLink

Amazon Cognito identity pools now support AWS PrivateLink, enabling you to securely exchange federated identities for AWS credentials through private connectivity between your virtual private cloud (VPC) and Cognito. This eliminates the need to route authentication traffic over the public internet, providing enhanced security for your workloads. Identity pools map authenticated and guest identities to your AWS Identity and Access Management (IAM) roles and provide temporary AWS credentials, with this new feature, through a secure and private connection.

You can use PrivateLink connections in all AWS Regions where Amazon Cognito identity pools are available, except AWS China (Beijing) Region, operated by Sinnet, and AWS GovCloud (US) Regions. Creating VPC endpoints on AWS PrivateLink will incur additional charges; refer to AWS PrivateLink pricing page for details. You can get started by creating an AWS PrivateLink VPC interface endpoint for Amazon Cognito identity pools using the AWS Management Console, AWS Command Line Interface (CLI), AWS Software Development Kits (SDKs), AWS Cloud Development Kit (CDK), or AWS CloudFormation. To learn more, refer to the documentation on creating a VPC interface endpoint and Amazon Cognito’s developer guide.
