Also, something that everyone will have to keep in mind:
If you are in another country and are on an account that is registered in a different country, then you will need to have a security token from the country you are registered to.
Q Is security token usage restricted by region?
A No, security token usage is not restricted by region. However, you can only link Square Enix accounts and PlayOnline IDs that are from the same region. If you have a North American PlayOnline ID, please obtain a North American Square Enix account.
In other words, I know players who are from Hong Kong and South Korea but can only play using an account registered to someone in Japan. Those players will have to get a security token that is linked in Japan, and it will get SENT there.
Another person I know plays in Italy, but has an account registered in the US with an American address. His token will be sent there.
There's the problem: You live in one country, but in order to play you have someone register you in an account such as US or Japan or European countries with an address there. Your token will be sent to that address, not where you live.
I doubt you will get banned, but that is up to SE themselves. But, the question is, those who are doing it that way, how will you get your tokens if you plan on using it?
I'm from the US so I won't have this problem. But, I have friends in other countries that plan on using it.
