If you have a specific app that you don’t want others to be able to access if they get ahold of your phone, you can lock the app with Face ID. When you do this, opening the app will require a scan of your face to open it. However, keep in mind that if Face ID fails, it will fall back to your device passcode. Here’s how to put a password on apps:

Find the app you want to lock, and long press on it.
When the menu appears, select Require Face ID.
Tap Require Face ID.
Face ID will scan your face.
When you open the app, there will be a full-screen blur telling you that Face ID is required to open the app.
If Face ID fails, you can tap Try Face ID Again.
If Face ID fails a second time, you can select Enter Passcode to unlock the app with your iPhone passcode.

That’s how to lock an app on the iPhone. Now you can keep your apps protected from prying eyes. Next, find out how to enable Face ID for private tabs in Safari.
