Guild Wars 2

So I have gotten 2 different texts on 2 separate occasion from a phone number that starts off with the title followed by a 5 digit number. I see no where I can put this code and tbh I am not sure what it is for. If someone can please let me know if someone is trying to break into my account or you are graciously trying to give me a dusk (:P), as I want to get to the bottom of this. I can provide the phone number I am getting texts from if need be

Thanks!

If so you are getting the text messages because someone is trying to log into your account.

Yes I think I did, and thanks ill take appropriate measures!
