Janina and I investigated the use of WebAuthn to establish personhood via a
known to be reliable authentication device, here is some progress.

I read the Cloudflare proposal and did the test. It worked very smoothly on
my iPhone using FaceID without any preliminary registration. This is huge
step forward from the first versions which seemed to indicate that users
would need a hardware key e.g. Yubico.

You can try the test here
