Technical issue with Token

I know there have already been security issues so I was planning on using a token for my account. HOWEVER, my wife and I share the same SE account login but different Final Fantasy Accounts (for simplicity, ease of billing, etc.). The problem lies in that I can only register one token per SE Account. Because of this, if we were to use a token, she has to grab my phone or text me (and hope I get back to her in time) for her to log in with that token. Can we look in to allowing multiple tokens like 1 per ffxiv account? It would work fine if we shared the same login/password but the one-time password would be accepted from either of our phones. You could still secure this by allowing only one device PER FFXIV ACCOUNT.

Are you talking about an actual physical token? As I am not understanding the deal about phones. I use a token still that I got for FFXI lol. When I log into SE I have to use it, and when I log into the game also. I would imagine you only need one but I would like to see what a rep says as I am curious.
2 accounts connected to one SE account with one token.

the phone tokens don't work much different, but the issue is really that since our 2 FFXIV accounts are "sub" accounts of our SE "joined" account, and I can only add one token (regardless of phone or physical); that it has to be there when either of us logs in... so if we are in different places and I have the token with me, she can't really log in.
