iPhone With Face ID-Locked Incognito tab

The Incognito mode in Google Chrome is quite helpful for private browsing. But what if you leave your iPhone unlocked? Chrome for iPhone’s new feature locks the Incognito tabs with Face ID so that others can’t check what sites you visit.

Using Face ID to unlock the Incognito tabs feature arrives as part of an experimental flag baked into Google Chrome 91 for iPhone. It applies an additional layer of security for the Incognito tabs, which requires unlocking them using Face ID, and also prevents anyone from snooping into your iPhone.

Warning: At the time of writing in June 2021, this feature is available as an experimental flag in Chrome 91. Google might eventually roll it out as a stable feature, or it might vanish from Chrome, as is always the case with flags. It also has the potential to break Chrome.

First, open the Google Chrome app on your iPhone. Then, type chrome://flags in the address bar and hit Enter.
