the question is why would we need this security on the forum? Many guys would like to check some news immediately instead of digging out the cellphone for the code. I think its an overhead that would block the flow of communication.
In the other view of course we would like to put everything into a safe to make us fell save.
It's needed because people keep getting their account hacked and this doubly protects them. It would only be needed everytime you log in as well so hardly a disruption. I doubt you will be
forced to use it either if you so wish, but if your account gets hacked and you haven't implemented it it will be your own fault. 2-factor will likely take less than a minute to actually input but I think the small delay will be worth your account being secure or at least having an additional layer of protection.
