Lock your Google Chrome browser
Today, My SO noticed a tiny button at the upper right corner of Google Chrome with her username on it. Apparently, it was once a hidden feature that can only be accessed through chrome://flags uri. Now, it seems that it has been rolled out to the public.
The lock option can only be enabled by toggling the Enable new profile management system option in the chrome://flags uri. You may notice that it is already in default. Choose the enabled option and relaunch the Google Chrome browser.
Now you can lock your browser and prevent random people snooping in and typing “po” in the address bar. Users can still browse using a guest account if enabled in the settings.
