Suspended login access? what?

[Kanash]

So yeah, I decided today that I would reactivate my 2nd account in FF14. Its been inactive for probably 8-10 months or so.

I logged in on the SE account fine, bought some crysta, reactivated my character.
Went to log in, and get this message:

Based upon recent suspicious activity, we have identified that your account may potentially be at risk. For your protection, we have temporarily suspended login access to this account.
Instructions for lifting this restriction have been sent to the email address registered to your Square Enix Account.

So what the heck...
