    * Базовая аутентификация по протоколу HTTP.
    * HTTP Digest и т.д.
* `oauth2`: все способы обеспечения безопасности OAuth2 называемые "потоки" (англ. "flows").
    * Некоторые из этих "потоков" подходят для реализации аутентификации через сторонний сервис использующий OAuth 2.0 (например, Google, Facebook, X (Twitter), GitHub и т.д.):
        * `implicit`
        * `clientCredentials`
