In this episode, Thomas Domville demonstrates the new Stolen Device Protection feature introduced in iOS 17.3. This feature is designed to protect against the rare instance when someone has stolen your iPhone and knows your passcode.

Thomas begins by explaining the purpose of the Stolen Device Protection feature. It prevents unauthorized individuals from performing critical device and Apple ID account operations, like changing your device passcode or Apple ID password. This is achieved by requiring biometric authentication with Face ID or Touch ID, with no passcode fallback.

He then moves on to the step-by-step guide on how to enable the Stolen Device Protection feature:

Go to Settings.

Note: If you don't see the Stolen Device Protection section, you may need to set up Face ID or Touch ID first.

The episode also covers the Security Delay feature, which requires a successful Face ID or Touch ID authentication, an hour wait, then an additional successful biometric authentication. This feature helps prevent someone from making changes to settings that can lock you out of your iPhone or Apple ID account.

Hello and welcome.

My name is Thomas Donville, also known as AnonyMouse.

I'm going to talk to you today about a feature called Stolen Device Protection.

Now this will be ultimately up to you if you want to turn this feature on.

This is a feature that will just kind of enhance your security protection for your iPhone and other settings.

I'll explain a little more here.

When this item is set to on, this will give you an additional protection when it comes to anytime that your phone is stolen or gets lost.

In theory, the feature came about, unfortunately, because there have been some incidents where people will be watching other people gain access to their iPhone, whether that's using the passcode or using their biometric authentication to get into the phone and thus forth then gets stolen from that person.

Or maybe perhaps you lost your phone and somebody somehow, someway gets onto your phone one form or another.

Well this protection will defeat from that person being able to make changes to some critical areas on your device.

So the first layer of protection when this is turned on, this will protect you from them being able to access to certain settings that will now require a biometric authentication.

So it kind of bypass if there weren't any passcode to that area before, you will now have to be able to use authentication by a biometric…
