Lock your screen
When stepping away from your Chromebook, make sure you lock your screen so no one can mess with your account. You may either click the lock icon in the status area or briefly press the power button (for 400 milliseconds, to be exact!) until you see the sign-in screen appear. For added security, you can also set your Chromebook to require a password for your account when waking up from sleep.
- If you haven't already, sign in to your Chromebook.
- Click the status area in the lower-right corner, where your account picture appears.
- Select Settings and find the "Users" section.
- Use the "Require password to wake from sleep" checkbox to adjust this setting.
You can also put your Chromebook to sleep by closing the lid. If you're not signed in, your Chromebook or Chromebox turns off. The screen also automatically turns off when it's been inactive for a period of time (8 minutes if the Chromebook is connected to a power source, 6 minutes if it's not). Press any key or swipe the touchpad with your fingers on your Chromebook, or shake the mouse on your Chromebox to wake them up. You'll find your windows and tabs preserved exactly as you left them.
Using your Chromebook at work or school? Your administrator might have set your device to require a password when waking up from sleep, in which case you won't be able to use this feature. Learn about using a managed Chromebook
