The update also added new options for those using the Stolen Device Protection feature; the latter protects iPhone owners by requiring them to verify their identity using Face ID or Touch ID to allow certain changes to be made to an iPhone. More sensitive changes, such as resetting Face ID, turning off the Find My app, changing the Apple ID password, changing the iPhone passcode, and disabling Stolen Device Protection requires identity verification by Face ID or Touch ID and a one-hour wait before the change is effected. The one-hour wait gives the iPhone user time to discover if his phone has been stolen allowing him to report the theft to Apple.
