+
+#### Utilisation d'un fichier `.env` et des scripts de démarrage
+
+Pour éviter d'exporter manuellement les variables d'environnement (API, SSH, notifications, JWT, base de données, etc.), vous pouvez utiliser un fichier `.env` à la racine du projet et les scripts fournis :
+
+1. **Créer un fichier `.env` à partir de l'exemple Docker**
+
+   ```bash
+   # Depuis la racine du projet
+   cp docker/.env.example .env
+   # Puis éditer .env avec vos valeurs (API_KEY, SSH_USER, NTFY_*, JWT_SECRET_KEY, etc.)
+   ```
+
+2. **Démarrer en développement sous Linux/macOS**
+
+   Le script `run_dev.sh` charge automatiquement les variables du fichier `.env` puis lance uvicorn :
+
+   ```bash
+   chmod +x run_dev.sh
+   ./run_dev.sh
+   ```
+
+3. **Démarrer en développement sous Windows (PowerShell)**
+
+   Le script `run_dev.ps1` lit également le fichier `.env` et définit les variables d'environnement pour la session avant de lancer uvicorn :
+
+   ```powershell
+   # Depuis la racine du projet
+   .\run_dev.ps1
+   ```
+
+   Ces scripts utilisent la même commande uvicorn sous-jacente :
+

+   python -m uvicorn app.app_optimized:app --host 0.0.0.0 --port 8000 --reload

 ### API REST
 
 #### Authentification
-Toutes les requêtes API nécessitent une clé API dans le header `X-API-Key`:
+
+L'application utilise désormais **une authentification JWT moderne** avec utilisateur/mot de passe et support des rôles.
+
+- **Mode recommandé (JWT)**
+  - Login avec `POST /api/auth/login/json` (ou `/api/auth/login` en form-data)
+  - Récupération d'un `access_token` (JWT) à transmettre dans le header `Authorization: Bearer <token>`
+  - Récupération des infos utilisateur avec `GET /api/auth/me`
+
+- **Mode legacy (API key)**
+  - Toujours possible via `API_KEY` et `X-API-Key`, mais **désactivé dès qu'un utilisateur est créé**.
+  - À utiliser uniquement pour la transition depuis les anciennes versions.
+
 ```bash
-curl -H "X-API-Key: dev-key-12345" http://localhost:8000/api/hosts
+# 1) Création du premier utilisateur admin (si aucune BD d'utilisateurs encore)
+curl -X POST "http://localhost:8000/api/auth/setup" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "username": "admin",
+    "password": "motdepasse-securise",
+    "display_name": "Administrateur"
+  }'
+
+# 2) Login et récupération du token JWT
+TOKEN=$(curl -s -X POST "http://localhost:8000/api/auth/login/json" \
+  -H "Content-Type: application/json" \
+  -d '{"username": "admin", "password": "motdepasse-securise"}' | jq -r .access_token)
+
+# 3) Utilisation du token pour appeler l'API
+curl -H "Authorization: Bearer $TOKEN" http://localhost:8000/api/hosts
 ```
 
+##### 🔐 Sécurité / bonnes pratiques JWT
+
+- **Clé secrète forte** :
+  - Définir `JWT_SECRET_KEY` dans `.env` avec une valeur longue et aléatoire (au moins 32+ caractères).
+  - Ne jamais committer la vraie clé dans le dépôt Git.
+- **Durée de vie raisonnable** :
+  - Utiliser `JWT_EXPIRE_MINUTES` pour limiter la validité du token (ex: 60 à 240 min en prod, 1440 min en dev/démo).
+  - Plus la durée est courte, plus l’impact d’un token volé est réduit.
+- **Stockage côté client** :
+  - Le frontend stocke le token dans `localStorage` pour simplifier l’intégration.
+  - Sur un déploiement exposé sur Internet, envisager des cookies HTTPOnly + TLS obligatoire pour durcir la sécurité.
+- **Rotation de clé** :
+  - En cas de suspicion de fuite, changer `JWT_SECRET_KEY` et redémarrer l’API : tous les anciens tokens deviennent invalides.
+  - Planifier un changement périodique de la clé (ex: tous les 6–12 mois) pour les environnements sensibles.
+- **Protection réseau** :
+  - Toujours exposer l’API derrière HTTPS (reverse proxy type Nginx/Traefik, certbot, etc.).
+  - Restreindre les IP/autorisations au niveau du pare-feu si possible.
