Unwarranted suspicious activity notification?

Attempted to log-in earlier this morning and I received the "suspicious activity" notification.

■ I only play Final Fantasy XIV on one computer.
■ No changes have been made to my internet settings, modem or router.

Can being logged into the Lodestone while trying to log into the game trigger this notification?

I've had this occur twice and just followed the prompts to "fix" it. Imo I don't think it has anything to do with your question as I have Lodestone open on one screen and I'm logged into it and the game(2nd monitor) at the same time. But, I could be wrong. xD
