The Challenge
Traditional username-password authentication created friction, security vulnerabilities, and recurring maintenance. The client wanted a login experience that removes passwords, accelerates authentication, and increases engagement without sacrificing security.
Too many user credentials to remember and reset
High risk of phishing, brute-force, and credential stuffing
Slow login flows, especially on mobile
Cross-platform complexity and scalability
Poor UX affecting user retention
Legacy password systems caused unnecessary friction and risk. A secure, passwordless approach was essential to improve user experience and trust.
Our Solution: QRCodeAuth — Scan → Approve → Login
We built a QR-based authentication ecosystem that links a registered mobile device to the user's account. Each login generates a secure QR code tied to a session token. Once scanned and approved, the website validates the device signature and completes login without passwords.
Device Registration
User signs in once on mobile → device is cryptographically linked to their account.
Visit Supported Website
Website displays a unique, time-limited QR code associated with the session.
Scan via App
User scans the QR and approves login instantly using their device token.
Instant Sign-In
Server validates signatures → session authenticated → user logged in.
