Hallo Ingo,

Google APIs use the OAuth 2.0 protocol for authentication and authorization. There are quite a few resources available on the Internet, covering this protocol in general.

OAuth is an authorization protocol, rather than an authentication protocol. Using OAuth on its own as an authentication method may be referred to as pseudo-authentication. You can read here about the way the OAuth 2.0 is used in Google products, or here. There are separate documentation pages for storage, compute engine, server-to-server applications, or specific to various APIs.
