Google Passwords are synced from Windows. Users should not change their Google password directly.
Faculty/Staff can change your Windows password by logging into your work computer, at work, and using CRTL-ALT-DELETE to select change password from the short menu. Password changes in Windows will immediately update Google.
Students cannot change their passwords themselves, but we are looking into allowing this feature. If your randomly assigned password is offensive, your teacher can help you get a new one.
