What about:

Windows only: To play three characters simultaneously
- A Square Enix account
- A copy of the Windows version
- Three registration codes obtained from the product or the "FINAL FANTASY XIV Service Center"
*You can register up to eight registration codes per Square Enix account.
*The "FINAL FANTASY XIV Service Center" website will be available after the game is launched. Please note that the website can only be accessed by those who purchased FINAL FANTASY XIV and registered a service account.


Also will it allow me to play the 2 characters I already have on my account simultaneusly?
