Ok. Got this today. with this message;

Dear Valued Square Enix Customer,
Thank you for using the Square Enix Account Management System.
We are writing to inform you that we have temporarily restricted access to your Square Enix Account. This was done for your protection as unusual access to your account was detected on our system. For your protection, we have temporarily closed the account.
I did what the email suggested and created a new password (annoyed about it since every game I play that requires a password, has its own unique password).

I would like to know what "unusual access" to my account means. I have been not been doing anything I consider unusual. What was so abnormal that required this extreme measure (and I do consider it extreme).

Is it just to try to encourage me to buy an authenticator?, was my account hacked?, seems doubtful, but if it was was it because of a breach on Squares End, since there is no keylogger on my system, and my FFXIV password was a unique string, only used for logging into FFXIV or the Square-Enix Website.

What was so abnormal about my account activity that caused my account to be locked? I want to know. Does square just randomly lock people's accounts on whims? Please Explain? In email, if you do not want to do it on the forums, but I am sure other people would like more detailed reasons than "unusual access" if they had their accounts locked.

Thank you for your time
G
