I should use it on my admin accounts, but I just use a very strong password. I don't think I'm going to get hacked, though.Considering I'm mostly active on just three different forums, Admin Junkies is the only one I use two-factor authentication on. I feel since I'm a staff member it's justified that I use two-factor authentication to better protect my account. Jcink, as mentioned above, doesn't have two-factor authentication available, but one thing it at least has available is a security question you can plug into your Admin CP.
