In iOS 17.4, Apple will allow you to have the Stolen Device Protection feature enabled at all times
Enable Stolen Device Protection as soon as you install iOS 17.3
But here’s where the real protection comes into play. With certain sensitive tasks that a thief needs to do to take control of your iPhone, such as changing your Apple ID password, changing your iPhone passcode, adding or removing Face ID or Touch ID, turning off Find My, and turning off Stolen Device Protection, there is a one-hour delay before Apple will allow any of these changes to be made. Even after the hour has passed, Face ID or Touch ID must be used to verify your identity. The hour delay gives the victim of an iPhone theft time to realize that his phone is gone and to call Apple and alert the company.
iOS 17.4 could be released on Monday, March 4th
Sure, you might find it inconvenient to wait an hour to change your passcode or Apple ID password. However, I believe that you’d find it more inconvenient to have someone steal your iPhone and go rifling through your financial apps while freezing you out of your own phone and private accounts. But hey, that’s just me.
