News has surfaced on the Square Enix authenticator tokens that keep Final Fantasy XI accounts secure. The company has announced that they will make available their security tokens on Tuesday, April 7th in Japan, North America and Europe. The tokens cost $9.99 and will be available for purchase through the PlayOnline viewer.
Additionally, if you opt to pick up a token, you'll get a special in-game bonus item called "The Mog Satchel" which grants additional inventory space equal to a character's Gobbiebag limit, potentially up to 60 slots.
