PrivacyAuth™
Privacy-Preserving 2FA • Passwordless Authentication
Zero-knowledge authentication that protects user privacy. Enable biometric 2FA without storing fingerprints or face scans. Users prove they are who they claim to be—without revealing any biometric data to your servers.
Why PrivacyAuth™?
Biometric data never leaves the user's device. Zero-knowledge proofs verify identity without transmitting fingerprints, face scans, or passwords.
Result: Impossible to breach what you don't store
One-tap authentication with Face ID or Touch ID. No passwords to remember, no SMS codes to wait for, no authentication apps to open.
Result: 40% reduction in authentication friction
GDPR and CCPA compliant by design. No biometric data storage means no data subject access requests, no breach notifications, no liability.
Result: Zero compliance incidents in 8 weeks
How PrivacyAuth™ Works
User authenticates with Face ID, Touch ID, or device PIN. Biometric data is processed entirely on-device using secure enclave hardware.
Your fingerprint or face scan never leaves your phone.
Device generates a cryptographic proof that the biometric matches the enrolled template—without revealing the biometric data itself.
Proof generation takes <500ms on modern smartphones.
Your server receives only the ZK proof and verifies it cryptographically. The server confirms identity without ever seeing biometric data.
Verification takes <100ms with standard cloud infrastructure.
Upon successful verification, your server issues a standard session token or JWT. User is authenticated and can access protected resources.
Standard OAuth 2.0 / OpenID Connect compatible.

Quick Start Example
// iOS Swift Example
import PrivacyAuth
let auth = PrivacyAuth(apiKey: "your-api-key")
auth.authenticate { result in
switch result {
case .success(let token):
// User authenticated, token contains session JWT
print("Authenticated: \(token)")
case .failure(let error):
// Handle authentication failure
print("Error: \(error)")
}
}Customer Success Story
