Use App Lock to Protect Your Privacy
You can lock apps containing private data, such as chat and payment apps, to prevent
unauthorized access.
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 unauthorized 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 Settings > Security > App Lock > Enable, 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.
This feature may vary by device.
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 phone, 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 phone, go to Settings > Biometrics &
•
password > Face Recognition and follow the onscreen instructions to enter the Face
Recognition screen and enroll 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 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.
> Password type, and select Lock screen
