| Use App Lock to Protect Your Privacy |
With App Lock, you can lock apps containing private data, such as chat and payment apps, to prevent unauthorised access. If you have enabled App Lock and set Face Recognition as the app unlock method, when your face is not detected by your device, the locked app can't be accessed again after it is closed unless you verify your identity. This feature intelligently protects your privacy and works better in a well-lit environment.
Enable App Lock
Go to , then follow the onscreen instructions to set the App Lock password and select the apps to lock.
If you have enabled face or fingerprint unlock, you can link App Lock with a face ID or fingerprint ID as prompted.
Not all devices support fingerprint features.
Enable Intelligent Protection for Locked Apps
If you have enabled App Lock and set Face Recognition as the app unlock method, the system will intelligently detect that it is a different face to normal and provide further security protection for locked apps. If your face is not detected, such as when someone else is using your device, the locked app can't be accessed again after it is closed unless you verify your identity. This feature works better in a well-lit environment.
The intelligent protection feature will be enabled automatically once you have set Face Recognition as the app unlock method in either of the following ways:
If you have enabled Face Recognition for your device, follow the onscreen instructions to link your face when you enable App lock. The intelligent protection feature will then be enabled automatically.
If you have not enabled Face Recognition on your device, go to and follow the onscreen instructions to enter the Face Recognition screen and enrol your facial data. Then enable Access App Lock to link your face with locked apps.
Change the App Lock Password or Security Questions
Enter the App Lock settings screen, go to 
> Password type, and select Lock screen password or Custom PIN as the App Lock password.
If you select Custom PIN, you can go on to set a new password and security questions.
Cancel or Disable App Lock
Cancel App Lock: On the locked app list, toggle off the switches beside the apps for which you want to cancel the lock.
Reset App Lock: Go to
> Disable App Lock > DISABLE. This will cancel all locks, and clear all app lock settings.
