Blizzard has made a device available to help those of us who play WoW feel a bit more secure when it comes to the integrity of our account. The device, called the Blizzard Authenticator is a small token (for you IT nerds, it's an RSA token-like device) that is tied to your account and generates a number that must be input each login.

The device can be purchased at the Blizzard Online store for $6.50. If you want more information or to read the FAQ go Here for more information.
