Long over due question; how do you guys with multiple accounts unlock the satchels* for them, or do you not care about it for multiboxes.
Can you activate it on the phone then delete it 10 times, or need 10 phones or?
It's not just deleting the app off your phone. That is a great way to screw yourself. :D
Install the app on your phone.
Do the registration crap.
Wait for a bit before logging into POL. (It can take ~5-15min for it to get fully activated and attached to your account.)
Verify that the token is active by looking for a new icon on the FFXI title screen (looks like a hardware token.)
As long as that icon is there, log into one of your characters and confirm that the Mog Satchel is accessible.
Shutdown FFXI.
Go back to your account page on POL and use the "EMERGENCY REMOVAL PASSWORD" to deactivate the token from your account.
Wait a few minutes again, then login to FFXI.
You should not have to enter the One-Time Password.
If it asks for it, then wait longer before trying to login.
Using the Emergency Removal password guarantees that you won't lose the satchel on deactivation, since it doesn't actually deactivate/remove the token on the account, it just suspends it because you "lost your phone". XD Another player told me he removed it normally and still kept his satchel, but the instructions specify that it'll get removed if you deactivate the token. It's just as easy to do it my way, which will work.
I don't actually remember if there were any restrictions on using the same phone for more than one account. I did use the same phone to do this for two accounts, but I also switched the active Google account between installs to match the emails that the FFXI accounts are registered to. :/
