.....ok, but i use fingerprint, and i think it is impossible to crack or something the fingerprint. It would be great to make an option if we want to use pin..
I know about face, can be easy to crack

ok but if you use your fingerprint to login to like apps those apps also have access to your fingerprint so I think it's more of a security measure than anything else but I wouldn't worry about it too much cuz if you're downloading apps from you know the Google app store then you should be fine but if you sideload apps don't use your fingerprint to sign in on those apps...
