Protect your sensitive connection data with these security features:
- On first launch, you'll be prompted to set a master password
- This password is used to encrypt your database and unlock the application
- Use a strong, memorable password - it cannot be recovered if forgotten
- Open Settings → Security
- Toggle auto-lock on/off
- When enabled, choose from:
- 5 minutes: Lock after 5 minutes of inactivity
- 10 minutes: Lock after 10 minutes of inactivity (default)
- 15 minutes: Lock after 15 minutes of inactivity
- When disabled, the app will never auto-lock (master password still required on startup)
- All connection data is encrypted using AES-256
- Passwords are hashed with Argon2 for maximum security
- Encryption key is derived from your master password
