# How to manage biometrics or PIN

FairyVault lets you access your wallet quickly and securely using biometrics or a PIN—no need to re-enter your private key or seed phrase every time. By enabling these features, you can log in within seconds while keeping your assets protected.

1. On the FairyVault home screen, tap your account name and then the settings icon.
2. Click "Security" and then choose "Biometric authentication" to view or change your current authentication setup. To update your PIN, select "Change PIN" and follow the on-screen instructions.
3. You can also customise how quickly the app auto-locks after inactivity. Tap "Auto-lock" and choose from options like a few seconds, several minutes, or never lock—depending on your security preferences.
