General DiscussionSteam - Authenticator "Sorry this isn't quite right"

Is it mobile authenticator?

yupp

If it is then go to your account and turn off the mobile authenticator,it happens to me too

So long as you know your email acct (For security purposes by Steam) then you're gtg

ok, i'll try.. thanks mate

I've heard of people who had this problem, and it's often because they're looking at their Steam guard for one of their alt Steam accounts and not the one they're trying to log in to.
