-- Gets an OpenID token, using a known Cognito ID. This known Cognito ID is
-- returned by GetId. You can optionally add additional logins for the
-- identity. Supplying multiple logins creates an implicit link.
--
-- The OpenId token is valid for 15 minutes.
--
-- This is a public API. You do not need any credentials to call this API.
