Amazon Cognito is now available as a core skill (aws-auth) in the Agent Toolkit for AWS . AI coding agents using the toolkit can now set up, configure, secure, and troubleshoot Amazon Cognito using best-practice workflows, helping developers implement secure sign-in flows for users, AI agents, and microservices faster. The Amazon Cognito (aws-auth) skill covers user pool and app client configuration, managed login and OAuth 2.0 flows, token management, JWT authorizers, passkey/WebAuthn enrollment, threat protection, Lambda trigger wiring, and identity pools.
