Sie erweitert lediglich OAuth2, indem sie einige Dinge spezifiziert, die in OAuth2 relativ mehrdeutig sind, um zu versuchen, es interoperabler zu machen.

Beispielsweise verwendet der Google Login OpenID Connect (welches seinerseits OAuth2 verwendet).

Aber der Facebook Login unterstützt OpenID Connect nicht. Es hat seine eigene Variante von OAuth2.

### OpenID (nicht „OpenID Connect“)

It just extends OAuth2 specifying some things that are relatively ambiguous in OAuth2, to try to make it more interoperable.

For example, Google login uses OpenID Connect (which underneath uses OAuth2).

But Facebook login doesn't support OpenID Connect. It has its own flavor of OAuth2.

### OpenID (not "OpenID Connect")

Помните, что вы можете использовать Markdown внутри описания, к примеру "login" будет отображен жирным шрифтом (**login**) и "fancy" будет отображаться курсивом (_fancy_).
