How do I use Face ID to download apps?

To use Face ID to download apps from the App Store, you need to enable it in your settings. Here's how:

1. Open the Settings app: Find the Settings app on your iPhone's home screen and tap it.
2. Navigate to Face ID & Passcode: Scroll down and tap on "Face ID & Passcode."
3. Enter your passcode: You'll be prompted to enter your device passcode.
4. Enable iTunes & App Store: Look for the "iTunes & App Store" option and make sure the toggle switch next to it is turned on (green).

Now, when you go to download an app from the App Store, you'll be prompted to use Face ID to confirm the purchase instead of entering your Apple ID password. Simply look at your iPhone, and it will authenticate the download.
