# Security Policy

Security is very important for FastAPI and its community. 🔒

Learn more about it below. 👇

## Versions

The latest version of FastAPI is supported.

You are encouraged to [write tests](https://fastapi.tiangolo.com/tutorial/testing/) for your application and update your FastAPI version frequently after ensuring that your tests are passing. This way you will benefit from the latest features, bug fixes, and **security fixes**.

### Sécurité et authentification

La sécurité et l'authentification sont intégrées. Sans aucun compromis avec les bases de données ou les modèles de données.

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}.

    "/with-oauth2-scheme",
    dependencies=[Security(oauth2_scheme, scopes=["read", "write"])],
)
async def read_with_oauth2_scheme():
    return {"message": "Admin Access"}


@app.get(
    "/with-get-token", dependencies=[Security(get_token, scopes=["read", "write"])]
)
async def read_with_get_token():
    return {"message": "Admin Access"}


router = APIRouter(dependencies=[Security(oauth2_scheme, scopes=["read"])])

All the security utilities that integrate with OpenAPI (and the automatic API docs) inherit from `SecurityBase`, that's how **FastAPI** can know how to integrate them in OpenAPI.

## Esquema de segurança OAuth2 { #oauth2-security-scheme }

# Security { #security }

There are many ways to handle security, authentication and authorization.

And it normally is a complex and "difficult" topic.

In many frameworks and systems just handling security and authentication takes a big amount of effort and code (in many cases it can be 50% or more of all the code written).
