/**
 * Interface for accessing Amazon Cognito Identity.
 * 

* 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. *
