      It is worth it if you will burn that good will by pushing for U2F in a situation where 2FA has already been in place and has proved sufficient for the current threat model, risk appetite and budget.

      Yes, you don't need to reword your same argument dozens of different ways. You would burn all your budget to make attackers jump through a few hoops, I would rather save up for a real solution. I understand, I just disagree 😛

      But if I can cheaply implement even sms based 2FA and it stops just a handful of attackers while I work towards a full on U2F solution the answer is yes. Part of that good will is accurately conveying the risks and trade-offs.

      Perhaps homeopathy can be practiced safely if you accurately convey the risks and tradeoffs. The placebo effect is real, it might help a handful of people. Homeopathy is still trash though.

      “Hey boss @taviso said on Twitter that 2FA is the essential oils of security so we are just going to turn off 2FA until we can deploy yubikeys to everyone k?” I mean come on man.

      And what if an attack that could have been stopped by a basic 2FA implementation succeeds and costs you? Or doesn’t immediately cost you, but the reputational impact of the breach impacts revenue? You may be okay with that. Not everyone will be, or can be.

      Please stop trying to turn this into a "don't let perfect be the enemy of the good" debate. That is not the issue. What about all the illnesses that could have been stopped by homeopathy? Not everyone will be okay with that Chris, get out of your ivory tower.

      Notice how it doesn't make any sense, because homeopathy doesn't cure any illnesses? That's intentional, think about it 😜

      But your entire point here is that 2FA “does nothing”, which is categorically false. The argument is absolutely making perfect the enemy of good. 2FA is not a perfect solution but it succeeds in numerous scenarios right now.

      No, it is not "categorically false", that is just your opinion and I disagree. Let's just leave it here, we're just going in circles. 🙂

          Tavis, this is a popular experience for InfoSec pros in orgs where something is better than nothing. But you appear (maybe wrongly) to be denying this. I know what your argument is but it isn’t bein played out in the same universe as the majority of us. Surely you get this?

          Frankly, "Surely you get this?" Doesn't read like you want a good faith discussion. Nevertheless, I will repeat (again again) that the issue here is that we do not have unlimited goodwill to burn, and cannot continually ask users to adopt new solutions to the same problems.
