So, as some of you know, I've been working on adding (optional) 2FA to the forum for a while now. I mostly finished this work late last year, and it's just been sitting in a folder, waiting for its day in the sun.
Well done! Another ''forum main dev'' project 
I like to hear that 2FA will be a optional feature, but depending on how easy is to use I would would probably use it in bitcointalk forum.
Just make sure not to add any 2FA that is connected with SMS and phone numbers, this is literally worst thing related with 2FA.
Now that being said, people should be aware of risks when using 2FA, that means if you lose backup codes you will lose your account, and not even theymos with all his mighty powers will be able to restore it.
Speaking about theymos, I wonder what is going to be his opinion about this
