Chrome OS allows others to use your device to browse the internet without keeping their browsing history. If you have children, this may be a concern for you. Here’s how to disable guest browsing.
1. Go to the upper-right corner of the screen and click the wrench icon. Select Settings from the drop down menu.
2. In the left pane, select Users.
3. In the right pane, uncheck the Enable guest browsing checkbox.
4. Close the Settings tab.
Bonus tip: You can also access the Settings – Users page by typing chrome://settings/accounts into the address bar and pressing ENTER on your keyboard.
