What Is iPhone Stolen Device Protection, and Should You Turn It On?

If someone steals an iPhone and also knows its passcode, that combination can create a much more serious security problem than losing the phone alone.

Apple's Stolen Device Protection is designed to make that situation harder to exploit.

For most people with a compatible iPhone, it is a security feature worth considering.

What does it change?

With Stolen Device Protection enabled, certain sensitive actions require Face ID or Touch ID instead of allowing the device passcode as a fallback.

Some especially important security changes can also trigger a Security Delay.

That can require biometric authentication, a wait of about an hour, and another successful biometric authentication before the change can be completed.

The inconvenience is intentional. It gives a legitimate owner more protection against someone who has both the phone and knowledge of its passcode.

What do you need?

Apple says Stolen Device Protection requires an iPhone with iOS 17.3 or later along with security features including a device passcode, Face ID or Touch ID, two-factor authentication for the Apple Account, Find My, and the required Location Services settings.

Turn it on

1. Open Settings. 2. Select Face ID & Passcode or the corresponding Touch ID option on a supported model. 3. Enter your passcode. 4. Find Stolen Device Protection. 5. Turn it on.

Apple also provides options controlling when the additional security measures apply.

The default behavior can use familiar locations such as home or work. You can alternatively choose to require the additional protection more broadly.

Understand the tradeoff before enabling it

Extra security can mean extra inconvenience.

If you later need to make a protected account or security change, you may encounter biometric requirements or an intentional delay.

That does not mean the phone is malfunctioning.

This does not replace good account security

Continue using a strong device passcode and two-factor authentication.

The bottom line

Stolen Device Protection adds meaningful safeguards for the particularly dangerous situation in which someone steals your iPhone and knows your passcode. The extra authentication and possible delay are deliberate security measures, not bugs.
