I was wondering the same thing recently. Like Sandinmygum, I have been using a physical security token I acquired from a copy of FFXI. I've had it attached to my account for years. How long do those little batteries last?
I also have an unused token from the FFXIV 1.0 collector edition that's 3 years old now. I'm stuck in Windows Phone purgatory until next summer, so I won't be able to use a smartphone token anytime soon. Edited, Aug 27th 2013 1:08pm by Chialing
