# 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}.

from fastapi import FastAPI, Security
from fastapi.security.http import HTTPAuthorizationCredentials, HTTPBase
from fastapi.testclient import TestClient

app = FastAPI()

security = HTTPBase(scheme="Other", description="Other Security Scheme")


@app.get("/users/me")
def read_current_user(credentials: HTTPAuthorizationCredentials = Security(security)):
    return {"scheme": credentials.scheme, "credentials": credentials.credentials}

    [FastAPI docs for HTTP Basic Auth](https://fastapi.tiangolo.com/advanced/security/http-basic-auth/).

    ## Example

    ```python
    from typing import Annotated

    from fastapi import Depends, FastAPI
    from fastapi.security import HTTPBasic, HTTPBasicCredentials

    app = FastAPI()

    security = HTTPBasic()


    @app.get("/users/me")

{* ../../docs_src/security/tutorial005_an_py310.py hl[5,9,13,47,65,106,108:116,122:126,130:136,141,157] *}

Sehen wir uns diese Änderungen nun Schritt für Schritt an.
