Battle.net Authenticator

      Recently, Blizzard just released a new product that to protect their customer's account from hacker, the Battle.net Authenticator and Mobile Authenticator. These products are devices which offer an additional layer of account security. The Battle.net Authenticator is a physical "token," its very small to fit on a key ring, and the Mobile Authenticator is an application which can be downloaded (often for free) on many mobile phones. These devices work by providing a secure authentication code upon command that will be unique to your Battle.net account. After an Authenticator is associated with your Battle.net account, the authentication code will be necessary for each client and Account Management log in, increasing your protection against standard compromise attacks.
