App Lock

WebLibre can lock a profile so someone using your phone cannot open that profile without authenticating first. This is useful if you share a device or want extra protection for a sensitive profile.

In the current app, this protection is configured per profile, not as one global browser-wide setting.

Turn It On

  1. Open the profile manager in WebLibre.

  2. Open the profile you want to protect.

  3. In the Authentication section, choose Profile password or Device lock.

  4. Under Auto-lock, choose when the profile locks again.

  5. If you choose Lock after a timeout, also set the Timeout.

Each profile has its own lock method. A profile password cannot be bypassed with your fingerprint or device PIN.

Available Options

Choose a Lock Method

Choose Profile password for a password specific to that profile, Device lock for Android’s fingerprint, face, or device PIN protection, or No lock. Anyone who can unlock the device can open a device-locked profile. Android protection needs a screen lock set up on the device; if it is unavailable, check Android’s screen-lock settings.

Keep a profile password somewhere safe. WebLibre cannot recover a forgotten one. Five incorrect attempts lead to increasing waiting periods that persist after an app restart.

Auto-lock

WebLibre offers three lock modes:

  • Lock in background — locks as soon as WebLibre goes into the background, such as when you switch apps or return to the home screen.

  • Lock after a timeout — keeps the profile unlocked for a limited time, then locks it after the selected timeout expires.

  • Lock on startup only — asks you to unlock once when the app starts, then stays unlocked until the app is fully closed.

If you switch in and out of WebLibre often, Lock after a timeout or Lock on startup only is usually more convenient. If you want the strongest protection, use Lock in background.

Timeout

If you use Lock after a timeout, the available timeout choices are:

  • 1 minute

  • 5 minutes

  • 15 minutes

  • 1 hour

The default timeout is 5 minutes.

What To Expect

When a protected profile is locked, WebLibre shows Profile is locked with an Unlock button. The app may also try to start authentication automatically when that screen appears.

For a device-protected profile, use the authentication offered by Android. For a password-protected profile, enter that profile’s password. If another profile exists, you can switch to it from the lock screen, even if the startup profile picker is disabled.

Important Notes

  • This feature protects the selected profile, not every profile at once

  • Each profile has its own lock method. Backing up, deleting, or replacing a locked profile requires its own unlock method, even while managing it from another profile. Changing or disabling a lock also requires authentication

  • Installed website apps and Custom Tabs tied to a locked profile require an unlock before showing their content

  • Profile passwords restrict access through WebLibre; they do not encrypt profile data stored on the device. A backup’s encryption password is separate

  • Containers separate selected browsing inside a profile, but do not have their own authentication lock

  • If you switch to a different profile, WebLibre restarts into that profile; if that profile is protected, you will need to unlock it before use

  • Set up an Android screen lock if you choose device authentication; a profile password does not use your device PIN
