To approve family purchases, iPhone X owners may be able to use Face ID very soon. In iOS 11.3 purchases on a parent’s device is possible with the Face ID after a single time request to enter the password. This way the parents would be able to control what their children purchase from the iTunes.Previously, it was observed that the parents were not able to control the purchases of their children, as it didn’t work with the Face ID. Parents were supposed to add their passwords manually for every purchase, and that wasn’t as secure as Face ID is.
This is another life improvement implemented by Apple in the iOS 11.3 update. This also includes several other enhancements and features like New Animoji, Battery Health, an update for ARKit and the ability to send locations to other while you are in an emergency.
