Physical authenticators are available for both games, with Final Fantasy XI players able to order one online and receive Goblin Bag storage space in return. The Final Fantasy XIV authenticator came with the Collector’s Edition of the original version of the game and came with no extra benefits.
Square Enix did not announce when the authenticator application would be available however, instead choosing to say that more will be announced at a later date.
