Blizzard Authenticator

If you’re afraid of key loggers taking over your precious World of Warcraft account, why not insure yourself against that dastardly deed with the Blizzard Authenticator? Retailing for just $6.50, you log in using the Blizzard Authenticator, and the device will give you a randomly generated, one-time use password to go along with your regular password. Every time you log in, the password generated will be different, making it a whole lot harder for anyone to get your hoard of gold the easy way.
