A feature called Stolen Device Protection makes it difficult for phone thieves to access critical settings and functions. Let’s take a look at how to set it up and how it works.

What Is iPhone Stolen Device Protection?

iPhone’s Stolen Device Protection is essentially a fail-safe feature that prevents thieves from wiping your iPhone or accessing your personal information, including your Apple ID. To use the feature, you must update your iPhone to iOS 17.3 or later.

Stolen Device Protection adds additional layers to iPhone security by requiring biometric authentication (Face ID and Touch ID) to perform certain actions when your iPhone is in an unfamiliar location. This means that someone who knows your passcode cannot steal your iPhone and wreak havoc. The feature also introduces a delay for some actions like changing your Apple ID password.

The feature directly targets scammers who contact owners of stolen devices in a bid to get them to hand over their passcodes.

How Stolen Device Protection Works

Per the official support page, the feature “adds a layer of security when your iPhone is away from familiar locations, such as your home or workplace.” Let’s break that down to understand how the feature works.

Once you enable Stolen Device Protection, your iPhone changes certain security settings. First, it will require biometric authentication to provide access to stored passwords or credit card information. Hence, thieves who notice and remember your passcode won’t be able to access such data.

Further, if your iPhone is away from a familiar place, such as your home, office, or another place you frequent, changing your Apple ID password or adjusting another security setting will require waiting an hour, followed by a second biometric authentication.

If it’s not you trying to make those changes, the feature will ensure they will fail. If someone steals your iPhone, the security delay will enable you to mark it as lost in the Find My app before the thief overrides the security settings and erases it. Turning off Lost Mode will also require Face ID or Touch ID authentication.

How to Turn on Stolen Device Protection

Although enabling the feature is straightforward, there are a few settings that you need to set up first. First, you must enable two-factor authentication for your Apple ID. The feature also requires Find My and Location Services to be turned on.

Further, it’s a good idea to set your home on Apple Maps before you enable the feature. You can do this by editing your own contact card to include your Home address (using the Phone or Contacts app). Once you take care of those, follow the steps given below.

Open the Settings app on your iPhone.

Head to “Face ID & Passcode.” Enter your passcode to continue.

Scroll down to locate the “Stolen Device Protection” option and tap on “Turn On Protection.”

This should enable Stolen Device Protection on your iPhone.

How to Turn Off Stolen Device Protection

To turn the feature off, head to the “Face ID & Passcode” menu, and under “Stolen Device Protection,” select “Turn Off Protection.”

The only downside to this feature is that you won’t be able to change the security-related settings if you’re, say, on a vacation or at your friend’s place. In that case, you’d have to wait an hour or head to your home or workplace to make the intended change.

Which Security Settings Are Affected by Stolen Device Protection?

Once you enable the feature, certain settings will require Face ID or Touch ID authentication. These include using passwords or passkeys saved in Keychain, using payment methods saved in Safari, turning off lost mode, and erasing all content and settings. Further, a few Apple Wallet settings also require additional biometrics, including applying for a new Apple Card, viewing virtual card numbers, and taking Apple Cash or Savings actions in Wallet.

The actions that require waiting an hour when the iPhone is not in a familiar location include changing the Apple ID password, signing out of your Apple ID, updating account security settings, adding or removing biometrics, and adjusting the passcode. Further, resetting all settings and turning off the Find My and Stolen Device Protection feature will also ask you to wait and re-enter the biometrics.

Stolen Device Protection has a few minor drawbacks but ultimately helps to protect your device in the event of a bad actor getting hold of your iPhone. If security is important to you, you should be using your iPhone’s built-in password manager or a good free alternative.
