Amazon Cognito Identity

<fullname>Amazon Cognito Federated Identities</fullname> <p>Amazon Cognito Federated Identities is a web service that delivers scoped temporary credentials to mobile devices and other untrusted environments. It uniquely identifies a device and supplies the user with a consistent identity over the lifetime of an application.</p> <p>Using Amazon Cognito Federated Identities, you can enable authentication with one or more third-party identity providers (Facebook, Google, or Login with Amazon) or an Amazon Cognito user pool, and you can also choose to support unauthenticated access from your app. Cognito delivers a unique identifier for each user and acts as an OpenID token provider trusted by AWS Security Token Service (STS) to access temporary, limited-privilege AWS credentials.</p> <p>For a description of the authentication flow from the Amazon Cognito Developer Guide see <a href="https://docs.aws.amazon.com/cognito/latest/developerguide/authentication-flow.html">Authentication Flow</a>
