* `oauth2`: all the OAuth2 ways to handle security (called "flows").
    * Several of these flows are appropriate for building an OAuth 2.0 authentication provider (like Google, Facebook, X (Twitter), GitHub, etc):
        * `implicit`
        * `clientCredentials`
        * `authorizationCode`
    * But there is one specific "flow" that can be perfectly used for handling authentication in the same application directly:

    * HTTP Basic 认证方式。
    * HTTP Digest，等等。
* `oauth2`：所有的 OAuth2 处理安全性的方式（称为「流程」）。
    *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，X (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。
