All credit goes to the original contributors as seen below. This is a only forked and ported copy that use Koa instead of Express as web framework.

This is a working skeleton of a Node.js/Express application with passwordless login (Web Authentication API, WebAuthN, FIDO2).

Live at https://56k.guru/webauthn

Tested with Windows Hello, Yubikey or Android lockscreen, more to come.

Using express and fido2-lib

Note: This is a heavily modified and improved version of github.com/fido-alliance/webauthn-demo

First clone this repo, then:

npm install

I repeat, you need to generate keys, certificate and serve using https for webauthn to work

cd keys

openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -sha256 -days 365 -subj '/CN=localhost'
openssl genrsa -out key.pem
openssl req -new -key key.pem -out csr.pem
openssl x509 -req -days 9999 -in csr.pem -signkey key.pem -out cert.pem

rm csr.pem

cd ..

node app

https://localhost:3000

docker build . --tag="hexagon/webauthn-skeleton"

sudo docker run \
