Can a Chromebook be configured to automatically lock the screen when I close the lid?
There is a discussion in If someone steals my chromebook while it's off, will him be able to see my cached data? about the security of user data for a Chromebook which has been shutdown, but I am trying to ensure user data is secure when the laptop is suspended by closing the lid. My device is a Samsung Series 5 running (obviously!) the latest version of ChromeOS. I've noticed that the default configuration has the laptop resuming with no password prompt after being suspended.
On a Chromium support page (Protecting Cached User Data), the following is mentioned as a risk which allows the encryption mechanism to be bypassed:
An attacker will be able to access all user data if the machine is suspended or logged in and screen locking is disabled.
I haven't been able to find more details yet on how to enable "screen locking".
Please note that I know there is a "lock" menu item I could select before closing the lid but I'm really trying to keep with what I believe is the spirit of the Chrome OS experience by minimizing any extra steps that stand between me and my personal computing. I want locking to "just work" (but of course I am willing to take the extra step of typing my password when I resume from suspend).
