Ela inclui uma forma para autenticação usando “third party”/aplicações de terceiros.

Isso é o que todos os sistemas com “Login with Facebook, Google, X (Twitter), GitHub” usam por baixo.

### OAuth 1

Havia um OAuth 1, que é bem diferente do OAuth2, e mais complexo, isso incluía diretamente as especificações de como criptografar a comunicação.

Não é muito popular ou usado nos dias atuais.
