Apple has released iOS 17.3 update, which includes a new anti-theft feature – Stolen Device Protection. It should provide additional security measures to prevent thieves from accessing iCloud and other important accounts, such as bank accounts and email, even if the attackers manage to steal the iPhone.

Unlike the usual iPhone security methods that rely solely on the lock screen passcode, which can be spied on by attackers, Stolen Device Protection requires biometric authentication. Users must use Face ID or fingerprint scanning for certain activities, such as accessing stored passwords or applying for a new Apple Card.

In addition, the update introduces a security delay for critical actions, such as changing an Apple ID password or iPhone passcode. According to Apple, this process involves “unlocking with Face ID or Touch ID, waiting for an hour, and then additional successful biometric authentication.” This delay is only activated when the user is away from their usual places, such as home or work.

How do I turn on Stolen Device Protection in iOS 17.3?

To enable anti-theft protection, users can go to the iPhone’s Settings menu, select Face ID and Passcode, enter their device’s passcode, and enable the Stolen Device Protection feature.
