To protect your privacy, always log out of a non-personal computer if you are taking an ATI assessment or on a computer in a personal account. Only shutting down the computer will NOT protect your account information. If you do not log out of your account and log off the computer (Ctrl+Alt+Del and select Log Off), the next person who uses the computer will have access to your accounts. This can allow someone else to take a proctored assessment in your name or have access to your personal accounts.
Remember, log out of everything and THEN log off the computer (Ctrl+Alt+Del and select Log Off). Protect your privacy!
