+
+## Security Improvements Implemented
+
+### JWT Secret Persistence
+- ✅ Created `/opt/media-downloader/.jwt_secret`
+- ✅ Permissions: 600 (owner read/write only)
+- ✅ Sessions persist across restarts
+- ✅ Fallback chain: File → Environment → Generate
+
+### API Authentication
+- ✅ 41 sensitive endpoints now require authentication
+- ✅ Only 2 public endpoints (login, websocket)
+- ✅ 100% authentication coverage on sensitive operations
+- ✅ Uses `Depends(get_current_user)` pattern
+
+### Rate Limiting
+- ✅ Installed slowapi v0.1.9
+- ✅ 43 endpoints protected with rate limits
+- ✅ Login: 5 req/min (brute force protection)
+- ✅ Read: 100 req/min
+- ✅ Write: 20 req/min
+- ✅ Heavy: 5-10 req/min
+
+### Media Authentication
+- ✅ Fixed broken thumbnails/images
+- ✅ Created `get_current_user_media()` dependency
+- ✅ Supports Authorization header + query parameter token
+- ✅ Frontend appends tokens to media URLs

+
+## Recommendations
+
+### Completed
+- ✅ JWT secret persistence
+- ✅ API authentication

+2. **HTTPS** - Already handled by nginx reverse proxy
+3. **Redis** - For distributed rate limiting if scaling
+4. **Monitoring** - Add rate limit hit monitoring
+5. **Alerting** - Alert on suspicious authentication attempts
