## Authentification HTTP Basic simple { #simple-http-basic-auth }

- Importer `HTTPBasic` et `HTTPBasicCredentials`.
- Créer un « schéma de sécurité » en utilisant `HTTPBasic`.
- Utiliser ce `security` avec une dépendance dans votre chemin d'accès.
- Cela renvoie un objet de type `HTTPBasicCredentials` :
    - Il contient le `username` et le `password` envoyés.
