QUANTUM RESILIENT SOFTWARE · AUTHENTICATION

Authentication without passwords. Without the cloud. Without the risk.

RJ Lee Group developed Greenlight™ to establish trusted human identity before a system unlocks. It replaces static passwords with an image-derived cryptographic credential and enforces phishing-resistant factors, so the reusable secrets credential theft depends on don't exist. Part of RJ Lee Group's Quantum Resilient Software — alongside Quantum Shroud™ for data in motion.

Greenlight is a passwordless, phishing-resistant authentication platform that establishes trusted human identity before a system is unlocked. It replaces static passwords with a cryptographic, image-derived credential and enforces phishing-resistant factors — CAC/PIV, Windows Hello, WebAuthn/FIDO2, and a PIN — so the reusable secrets that credential theft depends on simply don't exist. Greenlight runs local-first, maintaining authentication in air-gapped, forward-deployed environments, as part of RJ Lee Group's Quantum Resilient Software portfolio. 

The credentials attackers rely on shouldn't exist

 Stolen credentials are still the front door. 

Stolen credentials remain among the most common ways attackers gain access to a network — a password can be phished, reused, or cracked. Greenlight removes the target: there is no static password to steal. It enforces the phishing-resistant factors federal agencies are directed to adopt under OMB M-22-09. And because it runs local-first, identity holds when connectivity is contested or lost, so mission-critical access continues in forward-deployed and air-gapped environments. The result also eliminates most password-reset help-desk load — but the reason to adopt it is that it closes the most common initial access vector. 

Nothing to phish, nothing to reuse 

Strong enough for an air gap. Simple enough that nobody calls the help desk.

Greenlight starts where credential theft starts. Every authentication derives a new, single-use credential from a user-selected image — the image itself is never transmitted or stored as an image — and every sign-in is backed by phishing-resistant factors: CAC/PIV, Windows Hello, WebAuthn/FIDO2, and a PIN. 

 It was built for the hardest environments — disconnected, contested, high-assurance — and it's simple enough that the people using it never think about it. That combination is the point: security that holds where it matters most, without the friction that makes people work around it. 

How Greenlight works

Image-derived credential.
Image-derived credential

 A cryptographic credential is derived from a user-selected image. The image itself is never transmitted or stored as an image.

Platform capabilities

  •  Nothing to phish, nothing to reuse — every sign-in derives a fresh, single-use credential, backed by phishing-resistant factors: CAC/PIV, Windows Hello, WebAuthn/FIDO2, and a PIN. 

  • Image-derived cryptographic credential — the image is never transmitted or stored as an image. 

  •  Works when the network doesn't — local-first architecture maintains authentication in air-gapped and forward-deployed environments, including extended disconnected operation, with FIPS-approved derivation, an optional fail-closed FIPS mode, and a tamper-evident vault. 

  •  No cloud dependency, no central secret store — identity is established on-device, so there is no password database to breach. 

  •  Fits your existing stack — integrates with Active Directory, M365, Duo, and SCIM rather than replacing your identity infrastructure.

Frequently asked questions

What is Greenlight?

  •  Greenlight is a passwordless, phishing-resistant authentication platform that establishes trusted human identity using an image-derived credential and factors like CAC/PIV, WebAuthn/FIDO2, and a PIN — with no static password to steal. 

 How does passwordless authentication work without the cloud? 

  •  Greenlight runs local-first: identity is established on-device using a cryptographic, image-derived credential, with FIPS-approved derivation and a tamper-evident vault, so it works in air-gapped and disconnected environments with no cloud dependency and no central password store. 

 Why is Greenlight phishing-resistant? 

  •  There is no reusable password to phish or steal. Every sign-in derives a fresh, single-use credential backed by phishing-resistant factors, aligning with the federal phishing-resistant MFA direction (OMB M-22-09). 

 Does Greenlight work in disconnected or air-gapped environments? 

  •  Yes. Its local-first architecture maintains authentication when connectivity is contested or lost, supporting forward-deployed and air-gapped operations. 

 How does Greenlight fit our existing identity stack? 

  •  It integrates with Active Directory, M365, Duo, and SCIM, adding phishing-resistant identity rather than replacing your existing infrastructure.
