In-App Lock in GB WhatsApp Pro v18.80
Built-in PIN, pattern and fingerprint lock — secure the app or individual chats without a third-party locker.
How it works
What In-App Lock actually does
GB WhatsApp Pro ships with an app lock that protects the whole app with a PIN, pattern or fingerprint. You can also lock individual chats so that even on an unlocked phone, sensitive conversations stay private. The lock kicks in on every app launch and survives reboots and updates. No need to install a separate locker app, and the lock is independent of the system lock screen.

How to enable In-App Lock
4 steps, ~2 minutes. Settings persist across app restarts and updates.

Install GB WhatsApp Pro v18.80
If you haven't already, download the latest GB WhatsApp Pro APK from gbwhatts.pro and install it over the existing WhatsApp or as a fresh install. In-App Lock ships built-in — no extra modules or plug-ins.
-
Open the GBSettings menu
Open the app, tap the three-dot menu in the top right, pick GBSettings. Every GB WhatsApp Pro-specific feature lives under this menu — separate from the stock WhatsApp Settings.
-
Navigate to the Privacy section
Inside GBSettings, tap Privacy. In-App Lock is one of the toggles in that panel. Tap to open its sub-screen.
-
Enable In-App Lock
Flip the top toggle to ON. Most settings take effect immediately; a few (like custom themes or fonts) ask you to restart the app — accept the prompt and GB WhatsApp Pro reopens with the change applied.
