AuthN by IDEE is a multi-factor authentication solution designed to prevent credential phishing and password-based attacks. The product provides passwordless authentication that operates on a zero-trust, zero-knowledge architecture. The solution registers devices and enrolls users within seconds, storing all necessary authentication data within trusted devices. This eliminates the need for phishable backup methods that traditional MFA systems rely on. AuthN supports multiple login options including offline access, push notifications, QR codes, and WebAuthn. The product integrates with Microsoft 365 and various applications, including legacy systems. It is delivered as a fully SaaS platform that requires no additional hardware or software for deployment. AuthN implements a blockchain-based audit trail that prevents administrators from impersonating users and makes audit logs immutable. The solution collects no personal or organizational data as part of its zero-knowledge approach. The authentication system is designed to protect against credential phishing, brute force attacks, and adversary-in-the-middle (AiTM) attacks. It ensures that only trusted users can access trusted applications and services on trusted devices. AuthN is compliant with NIST, FIDO2, and PSD2 standards, and provides AES-256-bit and ECC-512 encryption.
