On some devices, when you lock the device using the app, your fingerprint scanner or facial recognition will not work next time you are trying to unlock. This is Android limitation and it cannot be avoided at the moment. If you want to use your fingerprint or face to unlock your device, unfortunately you should not use this app. But in any case be sure to try the app to see if your device is affected by this behaviour.
