Biometric Lock Premium
Protect sensitive files behind your device's biometrics — Face ID or fingerprint — so they can't be opened without you.
How it works​
- Lock a document so opening it requires biometric authentication.
- For password-protected PDFs, the password can be stored securely behind biometrics so you don't retype it each time.
- Clear saved password — available in the viewer's overflow menu when a biometric password is stored, to remove the saved credential.
Availability​
Biometric document lock is available on Android and iOS, and is a Premium feature.
