Today we launched the public beta of new features for Amazon Cognito User Pools that enable web and mobile app developers to easily add a sign in user experience and integrate SAML-based identity providers (IdPs). Now Amazon Cognito provides built-in user forms for sign up and sign in along with OAuth2 support. You can customize the built-in user experience and add it to your app with just a few lines of code. Your users can sign-in with your own user directory provided by Cognito User Pools or through corporate IdPs such as Microsoft Active Directory through SAML 2.0 federation.
