You can use app lock to restrict access to your app even when your system is unlocked. It works on desktop, web and mobile, and it is separate from the private vault — app lock covers the whole app, the vault covers individual notes.
App lock is part of the Pro plan and above. If a paid plan expires, app lock is switched off automatically, so set up your device's own lock screen if you rely on it.
| Method | Where |

| PIN or password | Desktop, web and mobile |
| Biometrics (fingerprint, Face ID) | Mobile |
| Security key | Desktop and web |
