I expanded my account number to 8 and make new charater ( Quick Wizard Setup ) . I got a problem that everytime I login with this new team the game instances all require authenticator code . It's annoying . The problem is that if I login through the old setup ( 5 accounts ) the game only need authenticator code for the first time and everything is normal . Battle.net app / login through browser also don't need authenticator any too .

Anyone knows how to deal with this ?

Thanks
