/**
 * Interface for accessing Amazon Cognito Identity asynchronously. Each
 * asynchronous method will return a Java Future object representing the
 * asynchronous operation; overloads which accept an {@code AsyncHandler} can be
 * used to receive notification when an asynchronous operation completes.
 * <p>
 * <fullname>Amazon Cognito</fullname>
 * <p>
 * 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.
 * </p>
 * <p>
 * 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.
 * </p>
 * <p>
 * To provide end-user credentials, first make an unsigned call to <a>GetId</a>.
 * If the end user is authenticated with one of the supported identity
 * providers, set the <code>Logins</code> map with the identity provider token.
 * <code>GetId</code> returns a unique identifier for the user.
 * </p>
 * <p>
 * Next, make an unsigned call to <a>GetCredentialsForIdentity</a>. This call
 * expects the same <code>Logins</code> map as the <code>GetId</code> call, as
 * well as the <code>IdentityID</code> originally returned by <code>GetId</code>
 * . Assuming your identity pool has been configured via the
 * <a>SetIdentityPoolRoles</a> operation, <code>GetCredentialsForIdentity</code>
 * will return AWS credentials for your use. If your pool has not been
 * configured with <code>SetIdentityPoolRoles</code>, or if you want to follow
 * legacy flow, make an unsigned call to <a>GetOpenIdToken</a>, which returns
 * the OpenID token necessary to call STS and retrieve AWS credentials. This
 * call expects the same <code>Logins</code> map as the <code>GetId</code> call,
 * as well as the <code>IdentityID</code> originally returned by
 * <code>GetId</code>. The token returned by <code>GetOpenIdToken</code> can be
 * passed to the STS operation <a href=
 * "http://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRoleWithWebIdentity.html"
 * >AssumeRoleWithWebIdentity</a> to retrieve AWS credentials.
 * </p>
 * <p>
 * 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 <a href="http://docs.aws.amazon.com/mobile/index.html">AWS
 * Mobile SDK Developer Guide</a>.
