A class action lawsuit claiming that Blizzard forces players to purchase authenticators to have any protection while playing the company’s games has been dismissed as “frivolous” by the StarCraft developer.

Filed by two people, the suit is seeking damages for “consumer fraud, unjust enrichment, negligence, breach of contract and bailment” related to StarCraft 2 and Diablo III, as well as an injunction against “tacking on undisclosed costs”.

Its claim that a Battle.net authenticator is required for minimum account security is “completely untrue and apparently based on a misunderstanding of the Authenticator’s purpose,” said Blizzard.

“Considering that players are ultimately responsible for securing their own computers, and that the extra step required by the Authenticator is an added inconvenience during the log in process, we ultimately leave it up to the players to decide whether they want to add an Authenticator to their account,” said the company.

“However, we always strongly encourage it, and we try to make it as easy as possible to do.”

The suit also insists that Blizzard did not communicate security updates to users following August's Battle.net breach – something the company said was “not true”.

“We explained the actions we were taking and let players know how the incident affected them, including the fact that no names, credit card numbers, or other sensitive financial information was disclosed. You can read our letter to players and a comprehensive FAQ related to the situation on our website.”

Blizzard then called the entire suit “without merit and filled with patently false information”.

“Blizzard deeply appreciates the outpouring of support it has received from its players related to the frivolous claims in this particular suit,” the publisher said.
