Oh please. Every business I’ve ever worked for has enforced MFA for corporate access. You’re acting as if “non technical users” are illiterate subhuman morons. Even my 90 year old grandparents trivially figured it out on their own.
I'm claiming the reverse - the human ones are the normal people who just want to use email without it berating them every time they log in.
Then your grandparents are technical users. Curiously, so are mine. Sorry to tell you that you're wrong though and you have not met the non-technical users.
I've had to try to help my aunt and uncle recover old Apple and Google accounts with complete failure because they've changed cell phone providers and didn't care that their phone numbers changed. At no point are they adequately warned this is the case, and recovery codes are a confusing additional layer that they don't understand.
So they basically lose everything and nobody is willing to help them. You are making a grand assumption about accessibility - not everyone has the capability to grok such a convoluted login process. The non-technical users often aren't morons - they are just differently abled. Maybe they are immigrants who didn't grow up with computers much because they were poor, or have a mental condition.
2FA fails spectacularly on accessibility.
Your reply is an example of the problem - completely oblivious to the users that are horribly underserved by 2FA as it exists.
You're reading what you want to read because your position has no strong foundation. At no point has a specific age or employee class been a cornerstone of the argument. You can simply wait for the day that you are screwed by bad 2FA and then it will be obvious how stupid it is. A mistake can happen to anyone - even the people that know what they're doing.
there are as many meanings of "technical" as there are crafts[0], a corporate job likely include many hours each day working at a computer where you will encounter a lot of the various UX patterns that anyone else would encounter.
You do not need to be a programmer or work in IT to know how to use a computer effectively.
On the other hand there are people that do not use computers nor smartphone features that aren't also offered in feature phones.
