Authenticator Locked due to failed attempts..

So this is the 2nd time in a week that I try to log in and it says that my authenticator is locked due to too many failed attempts and to contact blizzard support.

Keep in mind that I got this error on the first login attempt. I only access this game from a private computer, no one else uses this computer and I don't access the game from anywhere else.

If there is someone getting my password some how, nothing comes up on virus scans on my computer. Either way they don't have the authenticator so I don't really see much reason to worry about it. This is just a little ridiculous that I'm getting locked out of my account.

No one even technically needs to know my password to attempt and to the best of my knowledge i can't just change my login name to prevent people from continually trying to access my account.

So this is just a minor inconvenience but this is the second night this week that I've been unable to play for such a stupid reason like this. I don't tend to sign into this game before 8 PM so i'm just out of luck is what it's telling me..to no real fault of my own. If this keeps happening it's just going to get insanely annoying and there's nothing I can do about it as far as I can tell.
