OAuth2 with scopes is the mechanism used by many big authentication providers, like Facebook, Google, GitHub, Microsoft, X (Twitter), etc. They use it to provide specific permissions to users and applications.

Every time you "log in with" Facebook, Google, GitHub, Microsoft, X (Twitter), that application is using OAuth2 with scopes.

Sie umfasst Möglichkeiten zur Authentifizierung mithilfe eines „Dritten“ („third party“).

Das ist es, was alle diese „Login mit Facebook, Google, X (Twitter), GitHub“-Systeme unter der Haube verwenden.

### OAuth 1

It is quite an extensive specification and covers several complex use cases.

It includes ways to authenticate using a "third party".

That's what all the systems with "login with Facebook, Google, X (Twitter), GitHub" use underneath.

### OAuth 1 { #oauth-1 }

There was an OAuth 1, which is very different from OAuth2, and more complex, as it included direct specifications on how to encrypt the communication.
