The one identifier
you've never screenshotted.
Fingerprints end up on wine glasses. Faces end up on billboards. Retinas end up in a documentary about surveillance. Brown Eye Auth verifies identity using the single most unique pattern you own — one you have never shown a stranger, a camera, or a LinkedIn recruiter.
No credit card. No cameras aimed at anything you'd regret. Just the truth, turned around.
Chosen by security teams who really, thoroughly thought this through
Passwords leak. This doesn't.
Every other factor you own has already been exposed to somebody, somewhere. This one hasn't — and our entire compliance program is built around keeping it that way.
Built like it's guarding something
Everything a real identity platform needs — pointed at a factor no real identity platform has ever needed.
Continuous liveness detection
Distinguishes a real, living pattern from a photo, a mold, or a coworker's very committed prank. Checked on every single authentication, not just enrollment.
Zero-knowledge proof-of-match
We confirm the match without ever storing, transmitting, or displaying the raw scan. Mathematically. We really do promise.
Multi-factor rear authentication
Pair with a password, a hardware key, or a second and entirely different unique pattern for genuine defense in depth.
SSO, SAML 2.0 & SCIM
Drop-in identity provider for Okta, Azure AD, and any workforce brave enough to onboard it. Provisioning included.
Cross-device sync
Enroll once on the desk-mounted BLINK-1000 scanner. Authenticate from any registered reader, anywhere in the org.
Compliance-ready
SOC 2 Type Cheeks, ISO/IEC 69001, and a HIPAA stance our legal team asked us not to elaborate on here.
Three steps. One conversation nobody wants to have twice.
Enroll
Sit down with a certified enrollment technician and our patented BLINK-1000 rear-facing scanner. Takes about four minutes. Feels like considerably longer.
Encode
Your pattern is converted on-device into an irreversible cryptographic hash. Not an image. A hash. We cannot stress this enough, legally.
Authenticate
From then on, walk up to any registered reader and turn around. Confirm on your phone if prompted. That's the entire flow.

Trusted by the people who had to explain it upward
"We cut phishing incidents to zero. Employees also stopped writing their passwords on sticky notes — mostly out of principle."
"Rolling this out to 4,000 employees was, without question, the most memorable all-hands in company history."
"I have never once forgotten my credentials. I have, on the other hand, forgotten my badge. Frequently."
