on someone else's computer and forget to log off, the next person could read your mail. Google's will now give users a link that shows all machines currently logged into their account. It displays the
type of machine (PC, mobile phone), the IP address, and how long the machine has been logged in, giving users the option to log out of any machine they don't want reading their mail.
