## OAuth2

OAuth2是一个规范，它定义了几种处理身份认证和授权的方法。

它是一个相当广泛的规范，涵盖了一些复杂的使用场景。

它包括了使用「第三方」进行身份认证的方法。

这就是所有带有「使用 Facebook，Google，X (Twitter)，GitHub 登录」的系统背后所使用的机制。

### OAuth 1

有一个 OAuth 1，它与 OAuth2 完全不同，并且更为复杂，因为它直接包含了有关如何加密通信的规范。

如今它已经不是很流行，没有被广泛使用了。

OAuth2 没有指定如何加密通信，它期望你为应用程序使用 HTTPS 进行通信。

/// tip

在有关**部署**的章节中，你将了解如何使用 Traefik 和 Let's Encrypt 免费设置 HTTPS。
