As you know, XenForo recently announced that 2FA will be available in 1.5. My personal opinion about this is:
I find the 2FA feature to be a very good feature for XenForo marketing purposes however for general forums I find it overkill to make the logging process even more complex. Hell I don't even use 2FA for my mail address and I will be using it on a forum account? No thanks.
So maybe I'm the only one who doesn't like 2FA and perhaps other people are actively using it on their online services like email or social media accounts, I don't know. In my case, the only online activity where I use 2FA is banking and not because I want but because my banks requires me to have a token in order to make withdrawals.
How about you guys? Do you actively use 2FA for your online activities?
By the way, the following suggestion has been made inmediately after the feature was announced: Option to disable 2FA globally. So if you also don't like 2FA you might want to go and like the first post of that suggestion!
