Here's something special for our World of Warcraft readers out in Europe. Blizzard is introducing what you could call an optional layer of security for your World of Warcraft account through a new product they've come out with, called the Blizzard Authenticator.
Think of it as a key with ever-changing teeth that fit into an ever-changing lock meant specifically for you. Here's a brief description of the new product straight from the press release:
Designed to attach to a keychain, the lightweight and waterproof Blizzard Authenticator is an electronic device that generates a six-digit security code at the press of a button. This code is unique, valid only once, and active for a limited time; it must be provided along with the account name and password when signing in to the World of Warcraft account linked to it.
The Blizzard Authenticator will be available at Blizzard's Worldwide Invitational from June 28-29 (in France, no less) and will retail for 6 Euro (US$ 9). It'll also be made available from Blizzard's European websites in the near future for 6 Euro plus shipping.
UPDATE: It looks as if it'll be available in America too. There's an FAQ for the Blizzard Authenticator on the US Blizzard website. We've linked to it below, in case you want to know more about the nifty gadget.
