Last week, Apple released iOS 17.3 with a new security feature called Stolen Device Protection, which aims to help protect your data in case a thief has stolen your iPhone and obtained the password.
Stolen Device Protection helps thwart this vulnerability in two key ways. When enabled, the feature requires Face ID or Touch ID authentication (with no passcode fallback) before users can change important security settings like Apple ID passwords or device passcodes. It also enacts a one-hour security delay before users can change these security settings. This is designed to give victims time to mark an iPhone as lost before a thief can make critical changes.

Fatal flaw in Stolen Device Protection​

However, if a user has Significant Locations enabled and is currently located in a familiar location, they won’t get these extra layers of security.

“When your iPhone is in a familiar location, these additional steps are not required, and you can use your device passcode like usual,” states Apple in the Stolen Device Protection support documents. “Familiar locations typically include your home, work, and certain other locations where you regularly use your iPhone.”

Apple deems a location significant based on how often and when a user visits it.

the "fix" = "Fortunately, you can turn off Significant Locations by going to Settings > Privacy & Security > Location Services > System Services > Significant Locations. Once disabled, Face ID or Touch ID will be implicitly required to turn off Stolen Device Protection."

...but fwiw I am NOT finding ..."> System Services > Significant Locations" on my iphone15 pro running iOS 17.3. I then tried a search from main Settings and it does not find it either?? :unsure:

Big thanks! The picture guide showed me how / where to find it. Disabled here now in 17.3. Just curious to me that iOS Settings search did not find "significant locations" -- Also turning off significant locations gave a warning popup from iOS that this would interfere with various features... I disabled anyways consistent with this warning. Thanks again.
