If someone snatches an iPhone from your bag or forcibly takes it from your hands, it’s only natural to feel an immediate surge of anxiety. Beyond the frustration of losing your phone, there are additional concerns at play. What if they noticed me entering my passcode, granting them easy access to my messages, photos, and other sensitive data? While losing your smartphone is undeniably distressing, activating Apple’s Stolen Device Protection can swiftly limit a thief’s access to your smartphone information. Keep in mind that this feature is not turned on by default and must be enabled before any theft occurs.
Introduced with the release of iOS 17.3, Stolen Device Protection adds an important security measure to your smartphone when it is taken to a location you don’t typically visit. Here’s a brief overview of its functionality and the steps needed to activate it.
For an in-depth look at Apple’s anti-theft technology, take a look at WIRED security reporter Matt Burgess’s article from the previous year. If you’re looking for Android solutions, refer to my guide on utilizing Android’s theft detection functionality.
What Is Stolen Device Protection?
This feature is specifically designed for scenarios where a thief not only steals your iPhone but also has knowledge of your passcode, allowing them to unlock the device. Once they physically remove your phone and bring it to a location outside your regular haunts, the Stolen Device Protection measures will activate.
The primary function of this feature is to start requiring Face ID biometrics to access sensitive functionalities on the phone, such as using your Keychain passwords, viewing your saved payment information in Safari, and disabling Lost Mode. Even if thieves are aware of your passcode, it will no longer serve as an alternative; Face ID becomes essential for complete access. This also obstructs thieves from quickly erasing all your data to sell the phone, as that process will also require Face ID.
Alongside enforcing biometric authentication, Stolen Device Protection introduces a delay period for modifications to critical security features on the device. If a thief intends to log out of your Apple ID or disable Find My iPhone, they can’t simply hold up the phone in front of your face for a few seconds while fleeing the scene. Thanks to the feature’s automatic security delay, an hour must elapse before significant safety alterations can be made, requiring biometric confirmation at both the beginning and conclusion of this process.
How Do I Activate It?
Before you can enable Stolen Device Protection, you’ll need to set up a few foundational security features on your smartphone. You likely have Face ID and a passcode already activated on your Apple device, both of which are necessary for this feature to function.
In addition, ensure that two-factor authentication (2FA) is enabled for your Apple ID—a wise move even independent of Stolen Device Protection. To check if you’ve turned this on, go to Settings, tap on your name at the top, and select the Sign-In & Security tab. The middle section of this screen will indicate whether 2FA is enabled or not.
The final feature you’ll need to activate on your iPhone is Significant Locations. This function registers the locations you frequently visit, allowing your phone to determine whether it’s in a familiar or unfamiliar setting. According to Apple, this data is end-to-end encrypted and not accessible to the company. Finding Significant Locations can be a little tricky; navigate to Settings, then Privacy & Security, and Location Services. Scroll to the bottom to find the System Services category. Select Significant Locations, and you may be asked to unlock it using Face ID. Finally, switch the toggle to the right to finalize enabling this feature.
Great! Now you’re all set to take advantage of Stolen Device Protection. After all that preparation, the last step is simple. Go to Settings once more, then tap on Face ID & Passcode, and enter your passcode. Scroll halfway down the page, select the Stolen Device Protection option, and toggle it to the right.
