Stolen Device Protection is a feature Apple hopes will prevent the total loss of an Apple ID if an iPhone and passcode are stolen. Here’s how to get it set up.
Previously, a thief could learn a person’s passcode through social engineering or spying, steal the person’s iPhone, and quickly lock the person out of their Apple ID. After reports of such problems got out, Apple worked on a feature to help mitigate the risk of total loss after an iPhone was stolen.
As of iOS 17.3, Apple has provided users with a way to mitigate the threat of total loss of an Apple ID. A thief can no longer access critical information or change passwords without biometric authentication by enabling Stolen Device Protection.
