FFXIV Security Token

[EvianEverdeen]

I'm just wondering, once I link my security token to my SE account, how the heck does the login screen know which code is displayed on the security token after I press the red button? There's obviously no wi-fi signal inherent on the security token, just wondering how the device communicates with the SE servers.

The RSA security token are tuned and time based. So their system know what set of RSA security token you (as you registered it) and how many code it has ticked over already. It's magic, just enter the code you see after you pressed the red button.

It's not magic, it's a time-synchronized OTP.

I know.. but 'magic' sound much intriguing ;-)
