With the advent of the iPhone X, Apple introduced Face ID, a facial recognition system that allows users to unlock their devices and authenticate purchases with a simple glance. While Face ID is a secure and convenient way to protect your iPhone, it can also be used to add an extra layer of security to your apps.
To enable Face ID for an app, simply go to the app’s settings and look for the “Face ID” option. Once you’ve enabled Face ID, you’ll be able to unlock the app with your face instead of entering a password.
