Blizzard is offering one more way to keep your World of Warcraft and StarCraft II account safe, this time by making a standard, toll-free phone call to authorize any weird login attempts.

The creators of Warcraft and Diablo have already given paranoid players the physical Authenticator and Mobile Authenticator app to keep their accounts protected. Today, the Dial-in Authenticator becomes available for folks who'd prefer to keep it old school and use their landlines for security. It's only available to accounts in the U.S. right now, but that may change.

Blizzard has put together a FAQ for anyone curious about the dial-up option. Dial-in Authenticator FAQ [Blizzard]
