With FaceAuthorise Kit, you can protect an app by scan face (your face etc).
A demo for Kit is step by step in screenshots, please refer to take a look.
Eg. *Situation: User buy an expensive app of yours for his company on his device, and he only want some persons who can use this app.
It’s better if the app support function Face recognise: the owner can capture faces of 4~n persons -> the app will store these valid faces.
