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, Twitter, GitHub" use underneath.

### 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.

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.

    *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。
