🔒 Security

What’s Secure

✅ Auto-Generated Keys - SECRET_KEY and JWT_SECRET_KEY created automatically
✅ Password Validation - Strong password requirements enforced
✅ Secure Storage - Configuration saved with proper permissions
✅ Connection Testing - Validates credentials before saving
✅ API Validation - Tests OpenAI key before storing
✅ Setup Lock - Prevents accidental reconfiguration

Best Practices

  1. Use Strong Passwords - Wizard enforces minimum requirements
  2. Rotate API Keys - Change OpenAI keys regularly
  3. Backup Configuration - Save setup.json securely
  4. Enable HTTPS - Use SSL in production
  5. Restrict Access - Firewall setup wizard port after configuration
