WoW.com has learned through trusted sources close to the situation that Blizzard is giving serious consideration to making authenticators mandatory on all accounts. According to our sources, while this policy has not been implemented yet and the details are not finalized, it is a virtually forgone conclusion that it will happen.
This response is a direct effort to stop the massive number of compromised accounts by gold sellers and keyloggers. The seriousness of the situation with compromised accounts has reached such a level that wait times for item and character restoration are entirely unacceptable, even to Blizzard executives. Blizzard has taken other internal measures to deal with long wait times of people in account restoration queues, and we'll be covering those measures tomorrow.
However, with the inclusion of mandatory authenticators, this should solve a major problem for Blizzard's support and account administration teams.
