Damn, no need to be a d*ck man...

I wasn't trying to be a d man, sorry if i sounded like a d. if you don't own a cell phone(for whatever reason it may be), maybe you can install android os on a VM then install google authenticator.
I'm sure he will not do it because he is pretty sure about his password which is wont be easy to crack. For some people having 2fa is something that a little bit complicated and wasting time for them so they decided to make a really complicated password in order to make it hard to be hacked. Of course 2fa will be better but we cant push/force other to do it. It is just a recommendation, lets the players choose what they wish.
