i assume you mean the security token. that is 14 exclusive
That is not correct. The security token is a Square-Enix security token. You can attach a FFXI or a FFXIV security token to a Square-Enix account regardless of whether or not that account has an FFXIV or a FFXI Content ID associated with it. I associated my FFXI Content ID with my SE account, secured by the token I got with the FFXIV CE, and it all worked fine (and yes, I got the Mog Satchel).
