How to Buy An App on iPhone X Using Face ID

The old Touch ID way is to clcik the buy button, and then use your fingerprint to confirm the purchase. What happens with Face ID? How do you cancel a purchase after tapping buy? This tutorial aims to show you how to purchase apps using Face ID instead of using Touch ID.

To make a purchase via Face ID, you click the app’s price (labeled Get for free apps), and the familiar iOS 11 sheet slides up with the app’s details, and a Cancel button.

To abandon the purchase, click Cancel. To go ahead with the transaction, you now have to double-click the power button on the top right side of the handset. This initiates the Face ID scan, and installs the app.
