      I often hear the argument "we shouldn't call bad solutions bad, or people might not use the bad solution", but I strongly disagree and reject that argument. We have a good solution, and we're burning our limited goodwill on snakeoil. 2/2

      One of the main reasons this is still an argument over what advice to give people is the lack of companies supporting solutions like U2F, even most major banks only support weak/limited passwords + SMS 2FA. So people recommend it as a reduction of risk, however small that may be.

      These debates too often boil down to an infosec professional’s recommendation amounting to, “well if you can’t afford to implement all these best possible solutions you shouldn’t even be in business.” Sometimes it takes time to get there, and good enough just has to do until then

      Very strongly disagree, who would ever say that? I've never met anybody who argues it's perfection or nothing, most people in security are practical and realists. The debate here is that 2FA is *not* better than nothing.

      It’s never said verbatim, but it often goes that direction. I’m saying not every attacker will know how to bypass 2FA, which is flimsy AF, but that it is still better than nothing in some cases and situations.

      I really think you're misunderstood what someone was saying, who wouldn't pick a minor improvement if the only two options are nothing or improvement? However, I would pick "nothing" if the only options are nothing or homeopathy.

      Perhaps I misconstrued something, but I think comparing 2FA to homeopathy is incorrect. 2FA is not as strong a solution as it was, it’s not ideal, and it’s not going to protect anything, but it is better than nothing if options are limited or cost of moving forward is prohibitive

      How about this analogy: You complain that the lock on your door is being picked, so someone suggests adding a second pickable lock on the door. I would say no, it's nonsense solution that will inconvenience you and make you less likely to implement real solution in future.

      You say "trivial". Many orgs say "achievable". And 2FA isn't homeopathy, it's Aspirin. Legitimate but weak. Even the placebo of a second factor is hopefully enough to make an attacker move on.

      I think you've mixed your metaphors here, aspirin is not placebo. We're all on the same page that attackers do have to make changes to accommodate 2FA, that is self-evident. The debate is you think that's worth burning the limited goodwill we have for security, and I don't. 🤷‍♂️

          I meant that the "placebo" of anything beyond a simple password may prompt an attacker to move on. So 2FA has both that deterrent, as well as being legitimate but weak.

          There's only so many hoops people are willing to jump through, if you burn through them on trash like 2FA, then it's harder to ask them to implement U2F. Have you harmed security, or improved it? That's the debate 😛

          That limited goodwill has been burned already many times. We’ve gone from passwords to complex passwords you never write to password managers to 2fa to u2f. It’s like listening a schizophrenic. Who takes any advice seriously since it changes to different every time you ask it?

          Yep, totally agree. I guess I'm hoping there's some goodwill left and we can salvage it, but it's not looking good.

          I’d argue that you can burn just as much goodwill by pushing a new solution when the existing one may do the job for a given entity under the right circumstances, situation.
