Tous les protocoles de sécurités sont définis dans OpenAPI, incluant:

* HTTP Basic.
* **OAuth2** (aussi avec **JWT tokens**). Jetez un oeil au tutoriel [OAuth2 avec JWT](tutorial/security/oauth2-jwt.md){.internal-link target=_blank}.
* Clés d'API dans:
    * Le header.
    * Les paramètres de requêtes.
    * Les cookies, etc.

::: fastapi.Depends

## `Security()`

For many scenarios, you can handle security (authorization, authentication, etc.) with dependencies, using `Depends()`.

But when you want to also declare OAuth2 scopes, you can use `Security()` instead of `Depends()`.

You can import `Security()` directly from `fastapi`:

```python
from fastapi import Security
```

امنیت و احرازهویت بدون هیچگونه ارتباط و مصالحه ای با پایگاه های داده یا مدل های داده ایجاد شده اند.

تمام طرح های امنیتی در OpenAPI تعریف شده اند، از جمله:

* .
* **OAuth2** (همچنین با **JWT tokens**). آموزش را در [OAuth2 with JWT](tutorial/security/oauth2-jwt.md){.internal-link target=\_blank} مشاهده کنید.
* کلید های API:
    * <abbr title="سرصفحه ها">Headers</abbr>
    * <abbr title="پارامترهای پرسمان">Query parameters</abbr>

Все схемы безопасности, определённые в OpenAPI, включая:

* HTTP Basic.
* **OAuth2** (также с **токенами JWT**). Ознакомьтесь с руководством [OAuth2 с JWT](tutorial/security/oauth2-jwt.md){.internal-link target=_blank}.
* Ключи API в:
    * Заголовках.
    * Параметрах запросов.
    * Cookies и т.п.
