How to Lock Individual Chats in GB WhatsApp
GB WhatsApp allows you to lock specific chats without locking the whole app. There are three common methods: long press on a chat to access the lock icon, use the chat info menu to enable Lock Chat, or open GB Settings and tap Lock Specific Chats. After choosing your method, confirm the lock and set a password or fingerprint. Make sure your device has the required hardware support and the latest GB WhatsApp version installed.
How to Set Up Fingerprint Lock
Fingerprint is the fastest and most secure way to lock GB WhatsApp. Open GB Settings, go to Lock Settings, select Fingerprint, confirm your fingerprint on the sensor, enable Fingerprint Unlock, and save settings. Make sure your device has fingerprint hardware and at least one registered fingerprint in Android settings.
How to Use Pattern Lock
Pattern lock uses a swipe pattern like Android unlock. Open GB Settings, go to Lock Settings, select Pattern Lock, draw your pattern twice to confirm, and save settings. Pattern lock is less secure than PIN or fingerprint but easier to use.
How to Use PIN Lock
PIN lock uses a four to six digit number. Open GB Settings, go to Lock Settings, select PIN Lock, enter your PIN twice, and save settings. PIN lock is recommended for users who want strong security without biometrics.
Lock Settings Comparison

|---|---|---|
| Auto-Lock Timer | How long app stays unlocked | Set to 1 minute for best balance |
| Lock on Screen Off | Lock immediately when screen turns off | Enable for maximum security |
| Hide Lock Content | Hide chat content in notifications | Enable for private chats |
| Show Lock Icon | Show lock icon in status bar | Optional |
| Backup Lock | Require lock to access backups | Enable for sensitive data |
How to Unlock Locked Chats
To unlock a locked chat, open GB WhatsApp, go to the locked chat section at the top of the chat list, tap the chat, use your fingerprint, PIN, or pattern to unlock, and the chat remains unlocked for the auto-lock duration.
How to Remove Chat Lock
If you no longer want a chat locked, open the locked chat, tap the contact name, scroll to Lock Chat, toggle it off, and confirm the action. You can also remove multiple locked chats at once through GB Settings.
How to Recover If You Forgot the Lock
Forgetting the lock is uncommon but possible. Open GB WhatsApp, tap Forgot Password on the lock screen, enter your backup PIN if you set one, or use fingerprint if previously registered, or uninstall and reinstall the app and restore from backup. Always set a backup PIN to avoid losing access.
