You can lock Chrome incognito tabs on Android now. Bring it to the PC!

Jokes aside about Chrome’s incognito mode, the ability to open a private tab for sensitive browsing is incredibly useful. You can perform searches that you want to keep from affecting your recommendations or appearing in your search history—which applies as much to tax information and medical questions as anything more scintillating.

And now on all phones and tablets, you can protect your incognito tabs from prying eyes by locking them down. A quick tweak to Chrome settings on iOS and Android makes biometric or PIN authentication required to view your private tabs whenever you leave the app and then return. It’s an extra layer of protection for when you forget to close a tab when you’re done—easy to do if you’re constantly hopping between apps. No need to worry about banking info sitting unguarded, for example.

Trying to feature out for yourself is easy. If it’s rolled out to your Android device (or if you’re only now trying it on your iPhone or iPad), just tap on the three dot menu in Chrome, then Privacy and Security. Toggle on Lock Incognito Tabs When You Close Chrome. Now when you switch away from Chrome and then come back, you’ll have to pass an authentication check before you can see and interact with those private tabs again.

For folks who use incognito tabs more on mobile than dedicated apps, this feature is a very welcome addition—and one I hope to see come to desktop computers next. I leave my incognito windows open on PC for long stretches way more often than on a phone or tablet. I haven’t yet met a browser window stuffed with tabs that I didn’t like to keep around. And sometimes I’m reading up on something I don’t want roommates to know about; other times, I have private correspondence I’m working on that I really don’t want to be seen.

I can always lock my PC, but I occasionally forget to slam my fingers on Win + L before dashing off to deal with an overflowing pot or vomiting cat. The best alternative is setting up Dynamic Lock in Windows, but that only works if you move far enough away from your computer to trigger the auto-lock. It unfortunately doesn’t prevent someone also in your kitchen from wandering by your screen and teasing you about your recent discovery of r/illegallysmolcats. Ask me how I know.
