Safer Workstation is designed to turn removable devices such as an iPod or thumb drive into a user account "key". Even if someone has their computer require a password, anyone who knows the password can log in to the account -- passwords can be stolen. Introducing Safer Workstation. Simply run Safer Workstation and "tie" a thumb drive or iPod to the user account. When that drive is ejected, the user is logged out. Even if someone knows the log in password, Safer Workstation will notice that the key is missing and will log the user out.
