Chrome Lets You Lock Incognito Tabs With Biometric Authentication


  • Chrome will let you lock your Incognito tabs with Biometric authentication.
  • Available on Android and iOS.
  • Here’s how to enable it.

Ever wondered if there was a fingerprint lock for your Incognito tabs in Chrome? Google is finally bringing this feature to Chrome officially.

In a blog post, Google mentioned this new feature casually about “5 tips to stay safer online with Chrome”. It is an experimental feature and could be enabled via flags. Now, this feature is official on stable versions of Chrome on Android and iOS.

With this new feature, Chrome will lock the Incognito tabs behind fingerprint or biometric authentication when enabled. When you exit the Chrome browser to another app or home screen, the Incognito session will be accessible only after authenticating with biometrics. Chrome browser will show the ‘Unlock Incognito’ button. Clicking it will ask you to unlock the app with biometrics.

This feature is rolling out to all Chrome users in Android and iOS.
