This is a working demo/skeleton of a Node.js/Express application with passworless login (WebAuthN/FIDO2).

Supports authentication with Windows Hello, Yubikey or Android lockscreen (i think), more to come.

Using express and fido2-lib

Work in progress, but works!

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