A non-citizen living in Germany without the German eID because they’re not a citizen. Their country of origin doesn’t have any of that. I guess they don’t exist in that setup? Seems like a steep hill to climb on to solve some random login with captcha problem.

Binding login interaction to some government issued id…who’s entitled here.

Sounds like throwing a baby out with the bathwater.

Then have them go through the captcha process that already exists

Yeah, this is at least being discussed now for eID. Getting it to a point where it is actually usable for everyone and trusted by everyone will not be easy though. But even in the best case, this would cover maybe 5-10% of internet users in 5 years. What do you do with the other 90% ?
