Scan a QR with your phone and you’re instantly logged in (open-source, no app, no passwords)

I built QRAuth.io passwordless authentication, it works on any website or physical QR (menus, parking, ticketing, kiosks…).How it works in 8 seconds:

1. User sees an animated “living” QR on your site (rotates every 500 ms so screenshots are useless)

2. They point their phone camera at it

3. Tap once to confirm with biometrics/passkey

4. Boom, logged in. No typing, no copy-paste, no extra app.

It’s cryptographically signed (ECDSA + post-quantum), phishing-resistant, includes proximity proof, and fraud intelligence. Drop-in web components mean you can add it with literally one HTML tag or npm install .
Try the passwordless login flow or the beach-bar menu example, it’s kinda addictive. Would love your honest feedback:

• Does the “living QR” feel like magic or overkill?

• What use cases would you actually use this for?

• Any friction I should kill before I push it harder?

Happy to answer questions or hop on a quick call if you want to see the SDK in action.Thanks for taking a look!
