Google has added a new layer of security to its Chrome web browser, but only for those on iPhone. Chrome users can now secure Incognito Mode tabs with Face ID – the facial recognition feature built into the latest iPhone models. So, even if you hand over your smartphone to a friend and they launch the web browser, they still won’t be able to check what you’ve been viewing without passing the extra layer of security. 

If your iPhone doesn’t support Face ID, Google does allow users to rely on Touch ID fingerprint scanners or a passcode.

The new feature, which is rolling out to users worldwide right now, can be switched on by heading to the Settings menu, tap on Privacy then Lock Incognito Tabs. After that, each of your Incognito Mode tabs will be under lock and key until the security test is passed.

For those who don’t know, Incognito Mode stops your activity showing up in the web history menu or predictive search feature on Google, which suggests previous queries to speed up repeat searches.

Google just delayed its most controversial change to Chrome by a year

While Incognito Mode is great when it comes to shopping for surprise Birthday gifts on a shared device, it doesn’t hide your activity from your internet supplier, the company that makes your Wi-Fi router, or any of the websites you’re visiting. So don’t think of it as some kind of invisibility cloak.

Google revealed plans to add Face ID checks to Incognito back in February. After the necessary checks from beta testers, the update is now available.

The update is available across iOS devices. On shared gadgets, like an iPad, the ability to lock down your secretive shopping basket in Incognito Mode with a Face ID scan could be hugely helpful. And save a number of families from spoiled surprises.

You can download Chrome 92 from the App Store now.
