Google seems to be testing a tool to make anonymous browsing even more private in Chrome for iOS.
The beta version of the iOS Chrome app introduced a feature to require Touch ID or Face ID to unlock anonymous guides that you don’t want others to access. With the feature enabled, returning to Chrome after a closed session will show a blurred incognito tab and will require verification to be accessed, according to the release notes captured by 9to5Google. Google said in the notes that the purpose of the feature is “to add more security to your anonymous tabs”.
To enable the feature, go to settings, navigate to Privacyand select Block incognito tabs when you close Chrome. According to 9to5Google, the feature is not available to everyone running the beta version of the Chrome app on iOS. Google did not immediately return a request for comment on the feature and its broader implementation.
As 9to5Google noted, a version of this privacy setting is now available in the main Google search app, although this privacy setting is triggered after you leave the session for 15 minutes. To activate it, open the main Google application, go to settings, select Privacy and security, and enable the Enable Face ID for incognito mode.
