/**
 * Amazon Cognito
 * 

 * Amazon Cognito is a web service that delivers scoped temporary credentials to
 * mobile devices and other untrusted environments. Amazon Cognito uniquely
 * identifies a device and supplies the user with a consistent identity over the
 * lifetime of an application.
 * 
 * 

 * Using Amazon Cognito, you can enable authentication with one or more
 * third-party identity providers (Facebook, Google, or Login with Amazon), 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.
 * 
 * 

 * To provide end-user credentials, first make an unsigned call to GetId.
 * If the end user is authenticated with one of the supported identity
 * providers, set the Logins map with the identity provider token.
 * GetId returns a unique identifier for the user.
 * 
 * 

 * Next, make an unsigned call to GetCredentialsForIdentity. This call
 * expects the same Logins map as the GetId call, as
 * well as the IdentityID originally returned by GetId
 * . Assuming your identity pool has been configured via the
 * SetIdentityPoolRoles operation, GetCredentialsForIdentity
 * will return AWS credentials for your use. If your pool has not been
 * configured with SetIdentityPoolRoles, or if you want to follow
 * legacy flow, make an unsigned call to GetOpenIdToken, which returns
 * the OpenID token necessary to call STS and retrieve AWS credentials. This
 * call expects the same Logins map as the GetId call,
 * as well as the IdentityID originally returned by
 * GetId. The token returned by GetOpenIdToken can be
 * passed to the STS operation AssumeRoleWithWebIdentity to retrieve AWS credentials.
 * 
 * 

 * If you want to use Amazon Cognito in an Android, iOS, or Unity application,
 * you will probably want to make API calls via the AWS Mobile SDK. To learn
 * more, see the AWS
 * Mobile SDK Developer Guide.
