Blizzard just posted a press release where they share information about a new keychain token which generates unique codes used to help prevent unauthorized World of Warcraft account access.
This is pretty cool and having an extra layer of security will definitely reduce the chances of getting hacked, by a lot. To access my Internet bank, I use something similar and its very safe and easy to use.
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.
This optional security measure will be available for a cost of €6.00 at the 2008 Blizzard Entertainment Worldwide Invitational, which takes place June 28-29 in Paris, France. In addition, the Blizzard Authenticator will be made available for purchase via Blizzard Entertainment’s European websites in the near future for a cost of €6.00 plus shipping.
“It’s important to us that World of Warcraft offers a safe and enjoyable game environment,” said Mike Morhaime, CEO and cofounder of Blizzard Entertainment. “One aspect of that is helping players avoid account compromise, so we’re pleased to make this additional layer of security available to them.”
