Sécurité et authentification intégrées. Sans aucun compromis avec les bases de données ou les modèles de données.

Tous les schémas de sécurité définis dans OpenAPI, y compris :

* HTTP Basic.
* **OAuth2** (également avec des **tokens JWT**). Consultez le tutoriel [OAuth2 avec JWT](tutorial/security/oauth2-jwt.md).
* Clés d'API dans :
    * les en-têtes.
    * les paramètres de requête.
    * les cookies, etc.

De forma semelhante a [adicionar `dependencies` aos *decoradores de operação de rota*](dependencies-in-path-operation-decorators.md), você pode adicioná-las à aplicação `FastAPI`.

Nesse caso, elas serão aplicadas a todas as *operações de rota* da aplicação:
