A Future Without Passwords? How Quantum Tech Is Redefining Authentication June 2025 – VIT‑AP AIR Lab

In an era where password leaks, reuse, and brute‑force attacks dominate headlines, our team at the VIT‑AP Quantum Security Lab is proud to unveil a quantum‑resistant, passwordless authentication prototype built on open standards. Led by student researcher Aditya Mitra, Professor Sibi Chakkaravarthy Sethuraman, and Researcher Devi Priya V. S., our work tackles the twin challenges of usability and post‑quantum security head‑on.

Why Passwords Are Holding Us Back

• Reused and Cracked: Most users rely on the same passwords across multiple sites, making a single breach catastrophic.
• Vulnerable to Phishing and Key‐Logging: Traditional passwords can be harvested with alarming ease.
• Quantum Threats on the Horizon: Widely deployed cryptosystems like RSA and ECC—cornerstones of today’s secure connections—will succumb to sufficiently powerful quantum computers.

Our Quantum‑Safe Solution

1. WebAuthn + FIDO2 Ecosystem We leveraged the W3C’s Web Authentication (WebAuthn) standard together with FIDO2’s Client to Authenticator Protocol (CTAP2) to create a familiar “touch‑to‑login” experience.
2. ML‑DSA: A Post‑Quantum Signature Scheme At the heart of our design is ML‑DSA, a digital signature algorithm standardized in FIPS 204. ML‑DSA provides security even against adversaries wielding quantum hardware.

3. Real‑World Prototype

   • Device‑Resident Keys: Authentication keys are generated and stored within the user’s device hardware (e.g., secure enclave or TPM).
   • Tamper‑Proof Login: Biometric or PIN verification on the device unlocks the quantum‑safe key—without ever exposing it to the network.
   • Interoperability: Our prototype works seamlessly across browsers and operating systems that support FIDO2.

Key Highlights & Impact

• Phishing‑Resistant: No shared secrets travel over the wire, eliminating phishing and man‑in‑the‑middle attacks.
• Quantum‑Ready: By eschewing RSA/ECC in favor of ML‑DSA, we future‑proof authentication workflows against the coming wave of quantum cracking tools.
• User‑Friendly: One touch (or glance) to log in—no more memorizing or managing complex passwords.

What’s Next

• Field Trials: We are collaborating with partner organizations to deploy pilot programs in higher education and enterprise environments.
• Open‑Source Toolkit: Later this year, our complete FIDO2 ML‑DSA implementation will be published under an open‑source license for community review and integration.
• Extending to IoT: Work is already underway to adapt our approach to resource‑constrained Internet of Things devices.

“Our goal is to guide organizations toward a passwordless, quantum‑secure future—one tap at a time.” — Aditya Mitra, Student Researcher, VIT‑AP University
