What it does: QRAuth is a drop-in, cryptographically secure identity verification platform that lets users log in (or verify any action) by simply scanning a QR code with their phone. No passwords, no magic links, no SMS codes, no app install required. It works alongside your existing auth stack (Auth0, Clerk, Firebase, Supabase, etc.) or as a standalone solution. Every QR is cryptographically signed (ECDSA-P256 + post-quantum SLH-DSA), animated ("Living Codes" that rotate every 500 ms to kill screenshots), bound to the exact session, and includes proximity proof so you know the user was physically there. It also adds device trust scoring, 6-signal fraud detection, ephemeral guest access, and full WebAuthn passkey support under one unified identity model. Who it's for: Developers and product teams who hate auth friction and want passwordless login in <10 minutes. Anyone using QR codes in the real world (parking, events, hotels, kiosks, payments, ticketing) who needs to stop sticker fraud and fake scans. Teams building shared-device experiences (kiosks, TVs, public terminals) or high-security flows where phishing and replay attacks are unacceptable. If you ship QR codes today, digital or physical, QRAuth makes them tamper-proof and instantly verifiable. Why we built it: Passwords are broken. Magic links are slow and phishable. SMS is SIM-swappable. Passkeys are amazing but don’t work everywhere (shared devices, kiosks, physical products). We started with the physical world problem: fake QR stickers on parking meters and payment terminals were costing businesses millions. The same primitive that makes physical QR codes verifiable turned out to be the cleanest passwordless login method ever, phishing-resistant, works on any phone, and feels magical. We open-sourced the core (BSL → Apache after 4 years) because we believe authentication infrastructure should be transparent and composable, not another black-box vendor lock-in.

QRAuth.io is LIVE on Product Hunt in 1 Hour - Passwordless QR Login That Actually Stops Phishing

In exactly one hour we are launching QRAuth.io on Product Hunt! If you have ever been frustrated by passwords, magic links, TOTP codes, or (worse) the exploding QR-code phishing scams this one is for you. What is QRAuth?
Scan a QR code with your phone to instant, passwordless login.
No apps. No copy-paste. No passwords.
Every code is cryptographically signed (ECDSA + post-quantum SLH-DSA), living (refreshes every 500 ms), and backed by proximity proof + passkeys. It is basically WhatsApp Web but for any website, any physical QR, and any future AR glasses or implants. We built it because QR fraud exploded all over the world. People scan first and ask questions never. We decided the QR itself should prove it is legit before anyone scans it. Why we are excited
- Developers: drop-in Web Components + SDKs in less than 5 minutes
- Teams: phishing-resistant auth that users actually love
- Future-proof: open protocol (QRVA), transparency log, and ready for the scan everything world The site and demos are already live (no signup needed): Now it is your turn
We want this launch to be driven by real feedback from people who actually care about secure, delightful auth. Drop a reply and tell us:
- What is the most annoying part of login/QR flows you deal with today?
- Which use case excites you most (web apps, physical access, events, transit, retail...)?
- Any wild ideas for where cryptographic living QR codes could go next?
- If you have tried the demo already what felt magical and what needs polishing? Every comment, every suggestion, every upvote on Product Hunt today helps us ship better and faster. Let us make the physical + digital world clickably safe together. See you on the Product Hunt page in about 60 minutes!
Link drops here the second it goes live. Thank you for being part of this journey already The QRAuth team
