In order to give a control over the apps with FingerSecurity on your phone, you have to give permissions to FingerSecurity app in Usage data access. Tap the Open Settings and select FingerSecurity. Turn on the slider. It can be disabled later if under settings if you change your mind.

Below the slider there are custom settings. The custom setting allows you to use alternate password, timeout, protect notifications, specific fingers, etc. You can ignore if you don’t want to know what’s that and move on to the guide.



You can add as many apps you want. I have added WhatsApp too. All the apps you see in this area will be secured with your fingerprints.


Now let’s check if it works. Open the app that you have secured using FingerSecurity. I have added Contact so I will open Contacts app.


When you open the app, you will see a blue screen asking you to verify your fingerprint. At this moment, the back button becomes the home button. Don’t panic, it only happens on this screen. Put your finger on the fingerprint scanner. If you have successfully verified the fingerprint, the app will simply open. If not, there you have an alternate option to unlock it with the password you have set before.
