I have been using a security token since its introduction way, way back in FFXI. Now I know that the tiny battery should be good for quite some time and the one time codes are so numerous that I shouldn't ever run out.
It's a great way to control the login security of your account, however, it is a bit inconvenient to have to carry the physical device around with me all the time. On several occasions I have managed to forget it at home when going to game at a friend's house etc.
I would like to switch to the phone software version, which is very convenient, but I am not sure how this would be done. Can anyone point me in the right direction?
