Face ID doesn’t seem to work for approving family purchases on the iPhone X
If you thought it would be easier to approve family purchases on the iPhone X, you have another thing coming. As seen on Apple’s forums, people can’t seem to figure out how to use Face ID to approve family purchases. Users would need to manually enter password for it to work. In case you aren’t familiar, Apple has an Ask to Buy feature to help parents control what their children buy on their iOS devices. Before Touch ID worked but it seems to no longer be the case with iPhone X. Face ID works to authenticate a user when they make a purchase, but it doesn’t seem to work for this instance. Perhaps it’s a fail-safe to prevent kids who can dupe the phone’s facial recognition software and have them go to town with app-related purchases.
