Why It Matters (Zero Trust Approach)
-
Zero Trust Means Human Verification
Every login must prove:
- The user knows their rSecureKey and applies the correct color/style pattern
- The user controls their registered email and/or phone
Simple for users. Hostile to automation.
-
Passwords No Longer Create Trust
Passwords are reused, phished, and exposed at scale. Static credentials cannot defend against modern identity abuse.
-
MFA Without Cognitive Binding Falls Short
Blind approvals and replayable codes allow attackers to blend into normal login flows. Without human-bound validation, MFA becomes predictable.
-
Expanding Attack Surface
As adversaries evolve, older authentication layers become liabilities—putting sensitive systems and privileged accounts at increased risk.
How Rainbow Secure 2-Step Works
Step 1 — Enter Your rSecureKey
Users enter their secure key and apply their defined color/style pattern. If the formatting or pattern fails validation, the authentication attempt stops immediately.
Step 2 — Enter Your OTP
A one-time code is delivered via email or SMS, or split across both channels for distributed verification. User enters the code as received.
Alternatively, users may be challenged via the source IDP’s Authenticator app (Microsoft Authenticator, Google Authenticator) or Rainbow Secure TOTP Authentication
Step 3 — (Optional) Apply Color and Style Formatting
If configured, users apply the instructed color, font, or style formatting to the OTP—adding an additional cognitive verification layer that automation cannot execute.
Step 4 — Centralized Server Validates Identity
Rainbow Secure’s centralized authentication server processes the submitted formatted OTP, verifying credentials, visual formatting patterns, device context, and risk signals before granting access exclusively to the authenticated human user.
