In-App Lock in GB WhatsApp Pro v18.80
PIN, pattern or fingerprint lock built into the app — no third-party locker needed.
In context
Why people actually use In-App Lock
In-App Lock is a passcode, pattern, or fingerprint gate that opens before GB WhatsApp Pro shows your chat list — even after you have already unlocked your phone. The use case is privacy from people who share your device: a partner, a child, a colleague who borrows your phone for a moment. Official WhatsApp added biometric lock in 2021 but with two limitations GB WhatsApp Pro removes: official requires the OS-level biometric, so anyone who knows your phone PIN bypasses it; and official does not support pattern lock at all. GB WhatsApp Pro lets you set a passcode or pattern that is independent of the phone lock, so even someone with your phone PIN cannot open your messages without your separate WhatsApp lock. The fingerprint option is also available, and you can configure it per-chat — sensitive conversations get an extra lock layer while general chats stay open.
Deep Dive
What In-App Lock actually does
GB WhatsApp Pro has a built-in app lock that secures the entire app with a PIN, pattern or fingerprint. You can also lock individual chats so that even if someone has your unlocked phone, they cannot open your private conversations. No third-party locker app required, and the lock survives across app restarts.
Key benefits
- PIN, pattern and biometric lock options
- Lock individual chats separately from the app
- No external app required
How to enable
Enable In-App Lock in 4 steps
Total time: about 30 seconds. Requires GB WhatsApp Pro v18.80 to be installed first. If you have not installed yet, download from the homepage.
-
Open GB Settings → Privacy → Lock
Three-dot menu → GB Settings → Privacy → tap "Lock".
-
Pick a lock type
Choose Passcode, Pattern, or Fingerprint. Pattern works on any device; Fingerprint requires Android 6+ and a registered fingerprint.
-
Set your code and timeout
Enter the passcode / draw the pattern, then choose how soon after locking the device should re-prompt — immediately, after 1 minute, or after 30 minutes.
-
Optional: Lock specific chats only
Open any chat → three-dot menu → "Lock Chat". That chat now requires the lock to open, even from notifications.

Common mistakes
What people get wrong with In-App Lock
The most-asked support questions about In-App Lock come from these three patterns. Worth scanning before you enable.
- 1
Using the same lock pattern as the device unlock pattern. If someone watches you unlock your phone, they have the same code to enter GB WhatsApp Pro.
- 2
Forgetting to also hide notification preview. The lock keeps the chat list private, but a notification on the lock screen can still display the message content.
