QR Code Authentication

QR Code Authentication verifies users by having them scan or present a time-bound QR code to establish secure possession of a device or session. Typical flows include: (a) web shows a QR; the user scans with a trusted mobile app to approve login; or (b) a mobile app displays a QR that a branch device or kiosk validates.The QR encodes a nonce or challenge that’s signed or confirmed via a trusted channel, reducing password exposure and phishing risk. It’s used in banking logins, payment approvals, and branch/agent-assisted onboarding. Security hinges on short expiries, TLS, device binding, and replay prevention. For compliance, it supports strong customer authentication by adding possession and, often, biometric factors on the approving device, while offering low friction for users.
