* `http`: padrão HTTP de sistemas autenticação, incluindo:
    * `bearer`: um header de `Authorization` com valor de `Bearer` adicionado de um token. Isso é herança do OAuth2.
    * HTTP Basic authentication.
    * HTTP Digest, etc.
* `oauth2`: todas as formas do OAuth2 para lidar com segurança (chamados "fluxos").
    * Vários desses fluxos são apropriados para construir um provedor de autenticação OAuth2 (como Google, Facebook, Twitter, GitHub, etc):

Il nécessite une configuration un peu plus verbeuse. Et comme il est basé sur WSGI (au lieu dASGI), il n'est pas
conçu pour profiter des hautes performances fournies par des outils comme Uvicorn, Starlette et Sanic.

Le système d'injection de dépendances exige le pré-enregistrement des dépendances et les dépendances sont résolues sur la base des types déclarés. Ainsi, il n'est pas possible de déclarer plus d'un "composant" qui fournit un certain type.
