yes you can use authenticator but i dont know why you would i use auth on only my main account and if your using main account to farm or bot you got courage or stupidity no offense but if caught botting while using auth you have zero chance in getting account back because you cant use the i was hacked case so beware but another cool trick you can do is run program to mask your ip or change it to another location that is what i do and ive only ever got caught once botting and did the i was hacked claim i called it in and they gave it back
