### OpenID (nicht „OpenID Connect“)

Es gab auch eine „OpenID“-Spezifikation. Sie versuchte das Gleiche zu lösen wie **OpenID Connect**, basierte aber nicht auf OAuth2.

Es handelte sich also um ein komplett zusätzliches System.

Heutzutage ist es nicht sehr populär und wird kaum verwendet.

## OpenAPI

## OpenID Connect

OpenID Connect is another specification, based on **OAuth2**.

It just extends OAuth2 specifying some things that are relatively ambiguous in OAuth2, to try to make it more interoperable.

For example, Google login uses OpenID Connect (which underneath uses OAuth2).

But Facebook login doesn't support OpenID Connect. It has its own flavor of OAuth2.

    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。


## OpenID Connect

OpenID Connect 是另一个基于 **OAuth2** 的规范。

它只是扩展了 OAuth2，并明确了一些在 OAuth2 中相对模糊的内容，以尝试使其更具互操作性。

例如，Google 登录使用 OpenID Connect（底层使用OAuth2）。

但是 Facebook 登录不支持 OpenID Connect。它具有自己的 OAuth2 风格。

### OpenID（非「OpenID Connect」）

还有一个「OpenID」规范。它试图解决与 **OpenID Connect** 相同的问题，但它不是基于 OAuth2。

因此，它是一个完整的附加系统。

如今它已经不是很流行，没有被广泛使用了。
