-- Registers (or retrieves) a Cognito 'IdentityId' and an OpenID Connect
-- token for a user authenticated by your backend authentication process.
-- Supplying multiple logins will create an implicit linked account. You
-- can only specify one developer provider as part of the 'Logins' map,
-- which is linked to the identity pool. The developer provider is the
-- \"domain\" by which Cognito will refer to your users.
--
-- You can use 'GetOpenIdTokenForDeveloperIdentity' to create a new
-- identity and to link new logins (that is, user credentials issued by a
-- public provider or developer provider) to an existing identity. When you
-- want to create a new identity, the 'IdentityId' should be null. When you
-- want to associate a new login with an existing
-- authenticated\/unauthenticated identity, you can do so by providing the
-- existing 'IdentityId'. This API will create the identity in the
-- specified 'IdentityPoolId'.
--
-- You must use AWS Developer credentials to call this API.

-- | The expiration time of the token, in seconds. You can specify a custom
