Chrome can now lock Incognito tabs on Android behind biometric authentication

Google is rolling out a feature to Android that will add an extra layer of privacy when you browse websites in Incognito mode. The tech giant has revealed in a blog post (via The Verge) that the ability to lock Chrome Incognito sessions behind biometric authentication on mobile is currently making its way to Android users after debuting on iOS. When this feature is switched on, you will have to verify your identity through face or fingerprint authentication every time you return to an Incognito tab after exiting Chrome or navigating away to another app.

Locked Incognito sessions first became available on Android in 2022 — over a year after Google started testing it for iPhones and iPads — but as an experimental feature you'd have to activate via a flag. Based on 9to5Google's experience using it on Android last year, this feature will show you a gray screen with the Incognito logo at the center when you come back to a tab protected by the privacy feature. You'll then have to tap "Unlock Incognito" to open biometric authentication or choose to verify your identity with your PIN code.

While the feature isn't available for us yet, you can check out if you already have access to it by tapping on the three-dot menu at the top right corner of Chrome. Open Settings and then go to Privacy and Security to toggle on "Lock Incognito tabs when you leave Chrome" if you already see it as an option.
