How It Works
How Human Bound Authentication Actually Works
Circle Access operates at the architecture layer beneath your existing IAM, replacing transferable credentials with biometric-bound cryptographic human identity.
The Authentication Flow
User scans QR code with registered biometric-bound device
Device generates cryptographic proof of human presence (no credential transmitted)
Circle Access validates device trust, biometric match, and human identity
IAM system receives authenticated session with verified human identity
Credentials never exist in the flow. Authentication happens entirely through cryptographic verification between trusted devices and the Circle Access protocol.
Under the Hood: Protocol Architecture
Seamless Integration Beneath Existing IAM
Circle Access integrates via open standards (SAML, OIDC, SCIM) to enhance existing IAM systems without replacement, maintaining policies, access roles, and Zero Trust compliance.
Trust Humans, Not Data
Circle Access registers and cryptographically binds devices without collecting telemetry or user data. Identity proofing happens locally on the device, ensuring privacy and compliance without surveillance. Human bound authentication means proving who is there, not tracking where they go.
