Getting it running

First clone this repo, then:

1. Install dependencies

npm install

2. Generate self signed certificate and keys (webauthn requires HTTPS)

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 ..

3. Start server

node app

4. Open browser

https://localhost:3000
