If someone no longer uses your Pixelbook regularly, you can remove their account.
- On the sign-in screen, select the profile that you want to remove.
- In the lower-right corner of the profile picture, select the Down arrow
- Select Remove this user.
- In the box that appears, select Remove this user.
When you remove an account, it's only removed from the device. The Google Account itself, including its data and settings, will still exist.
