With the latest update to Chrome for iOS, you can protect your incognito tabs with Touch ID, Face ID, or a passcode (through MacRumors). Once the new feature has rolled out for you, you can enable it by going to the settings menu, then tapping “Privacy,” then “Lock Incognito Tabs.” I just updated the app and the option wasn’t there for me so you may have to wait a while to enable it. Google first revealed that it was testing this new privacy feature in February.
The update brings a few other useful features to Google’s mobile browser, including the ability to take a full-page screenshot of a website. You can use it by taking a screenshot with the button combination specific to your device, tapping the screenshot preview and then tapping the “Full Page” tab that appears, according to 9to5Google. (I don’t have this feature yet either.)
You can use Chrome 92 . to download now from the App Store.
