... I don't think Theymos has the intention of implementing 2FA authentication in this forum anytime soon.
He is, and theymos already give a thumbs up on what PowerGlove is creating
[1], it will be up anytime soon actually. But let's see until theymos implement it successfully coz it's something a pain in the as merging to the current forum.

https://bitcointalksearch.org/topic/a-concise-2fatotp-implementation-smf-patch-5457330PowerGlove seems to be making this into a reality soon. I think adding 2FA definitely has got many advantages. It id one of it's kind that can secure your identity for sure. I know that signing a message can be done effectively on this forum and it is already been done with staked bitcoin addresses however there is no harm at all in having additional security like this. If one address can be staked then hundreds of them can be stakes from different accounts too. I think there are loop holes to it for sure.
It's frequent phenomenon that people lose their 2fa keys and if it's decentralized app there is no recovery option available and they get locked out. If 2FA gets implemented, we all should be aware of the possibility of this to happen here on bitcointalk as well.
My idea is to leverage the combination of 2FA + Staked BTC address to enhance the security of user account, this is by giving user an option to recover 2FA keys with staked Bitcoin address in case user loses the 2FA key. While enabling 2FA, staking Bitcoin address should be must.
Also, 2FA implementation shouldn't be based on mobile number, mobile numbers are weak link in many crypto attacks. Stick with authenticator app, thank you!
This is also excellent thought. Having 2FA based on your cryptographic identification. May be something related to your signed message only. This signed message can be synched up with the back end algorithm that will verify it on continuous basis and then verify the real identity of the account. This way bot the things can get verified, address holder, the account holder, and will have amazing security too.
