Federated Identities Concepts

Amazon Cognito Identity enables you to create unique identities for your users and authenticate them with identity providers. With an identity, you can obtain temporary, limited-privilege AWS credentials to synchronize data with Amazon Cognito Sync, or directly access other AWS services. Amazon Cognito Identity supports public identity providers—Amazon, Facebook, and Google—as well as unauthenticated identities. It also supports developer authenticated identities, which let you register and authenticate users via your own back-end authentication process.
