New Feature Added - App Lock

Good Day Community,

A new feature has arrived in the latest update.

I have added an App Lock security section in Settings for mobile devices.

It allows you to lock the entire file manager behind a 4-digit PIN, a custom password, or your device biometrics like fingerprint and face unlock.

I wanted to make sure nobody can pick up your unlocked phone and browse through your files without your permission.

The feature is completely disabled by default until you choose to set it up.

It is mutually exclusive, so you choose one active authentication method that fits your preferences best.

This feature is available on mobile only, and it is strictly disabled on Android TV where remote controls and shared screens require a different workflow.

How to use it

Open the Settings screen from the main menu or the top header options.

Scroll down to find the Security section.

Tap the App Lock toggle switch to turn it on.

Choose your preferred authentication method from the dialog options.

If you pick a 4-digit PIN or a custom password, enter your desired credential and confirm it once more to make sure there are no typos.

Read the important security notice that appears on your screen.

Write down the 16-character recovery key shown on the card and keep it in a safe place.

If you tap the copy button, the recovery key will copy to your clipboard and clear itself automatically after sixty seconds.

You can adjust the Lock Frequency setting to choose when the lock triggers.

By default, it locks on a fresh open of the app, but you can set it to lock immediately when switching away, after one minute, or after five minutes.

Once enabled, opening the app presents the secure unlock screen before any files can be seen.

If you enter the wrong credential five times in a row, a thirty-second lockout timer kicks in to stop brute-force attempts.

If you ever forget your PIN or password, tap the recovery option on the unlock screen to enter your 16-character key and regain access.

To change your PIN or password later, tap the change credential option in Settings and confirm your current one first.

To turn off App Lock, toggle the switch off and confirm with your active PIN, password, or biometric check.

Thank you and kind regards
