This may sound like a silly question, but bear with me!

I mainly play FFXIV on my desktop PC, but would like to play on my laptop when away from home. I installed the game on my laptop and tried to log in, but my account was instantly locked. I was then emailed a security threat email informing me that someone had attempted to log into my account on another computer and giving me a link to change my password.

So my question is: is it possible to actually play the game on more than one computer? If so, how do I get around the security threat thing?

Thanks in advance for any advice
