If you're wondering how to put a password on your apps, Face ID is a great way to go.
This article will tell you how to set up Face ID in an app. Face ID can be used to unlock apps on the iPhone. For example, when I open my Day One journaling app, it pretty quickly recognizes it’s me and lets me in. This saves me from needing to enter the passcode. Whether or not Face ID works with an app depends on the app’s developers and what they’ve programmed the app to be able to do. But you can easily see which of your apps will work with Face ID within Settings; you can also turn Face ID on for apps in the same place. Here’s how to put Face ID on apps in settings on the iPhone.
