This is a work in progress (but working) skeleton of a Deno/Opine application with passwordless login (Web Authentication API, WebAuthN, FIDO2).

Node version (Koa and @hexagon/webauthn) live at https://56k.guru/webauthn Deno version (Deno, Opine and @hexagon/webauthn) live at https://56k.guru/webauthn-deno

• Tested with Windows Hello, Yubikey or Android lockscreen, more to come.
• Supports adding more than one authentication method to the same account.
• Supports transfering account to another device by a time limited one time link or QR-code.

Using Deno, Opine and fido2-lib

There are multiple versions of this demo available in different branches

First clone this repo, then:

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 ..

Using deno tasks (>=1.21.0)

deno task start

Or manually

deno run --allow-read --allow-net --allow-env --allow-write --lock=lock.json ./app.ts
