OAuth2 включает в себя способы аутентификации с использованием "третьей стороны".

Это то, что используют под собой все кнопки "вход с помощью Facebook, Google, Twitter, GitHub" на страницах авторизации.

### OAuth 1

Ранее использовался протокол OAuth 1, который сильно отличается от OAuth2 и является более сложным, поскольку он включал прямые описания того, как шифровать сообщение.

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

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

### OAuth 1

Es gab ein OAuth 1, das sich stark von OAuth2 unterscheidet und komplexer ist, da es direkte Spezifikationen enthält, wie die Kommunikation verschlüsselt wird.

    *以下几种流程适合构建 OAuth 2.0 身份认证的提供者（例如 Google，Facebook，Twitter，GitHub 等）：
        * `implicit`
        * `clientCredentials`
        * `authorizationCode`
    * 但是有一个特定的「流程」可以完美地用于直接在同一应用程序中处理身份认证：
        * `password`：接下来的几章将介绍它的示例。
* `openIdConnect`：提供了一种定义如何自动发现 OAuth2 身份认证数据的方法。
    * 此自动发现机制是 OpenID Connect 规范中定义的内容。


!!! tip
    集成其他身份认证/授权提供者（例如Google，Facebook，Twitter，GitHub等）也是可能的，而且较为容易。
