# Setting Up App Lock

App Lock ensures your wallet is protected when you are not actively using it.

1. Go to **P**rofile > **Security** > **App Lock**.
2. Set the inactivity timeout that triggers the lock screen (e.g., Immediate, 1 min, 5 min).
3. Ensure your PIN and biometric authentication (Face ID / Touch ID) are configured for quick and secure unlocking.
