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.
