      What's the correct minimum length for a password? 6 chars? 8? A number that isn't even? Here's what the big guys do (and why there's much more to it today than just length):https://www.troyhunt.com/how-long-is-long-enough-minimum-password-lengths-by-the-worlds-top-sites/ …

      Don't have big, systematic data on this but I constantly hear all over the world from people without any 2FA whose accounts get taken over via password reuse and much rarer live phishing of SMS 2FA. I do push people to U2F but, ceteris paribus, SMS 2FA seems way better than none.

          It happens rarely for opportunistic phishing because the economics don't make sense. Why change your code to increase victim yield by 1%? If that number increases, so will attacks. If 1% of users had to type "banana" into a form field, they would also be phished less.

          Would you argue that my banana-factor authentication scheme is better than none if it has the same property of reducing opportunistic phishing when only enabled for 1% of users?
