    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 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.
