Phi Passwordless Authentication

The password prompt is gone. You log in, and it just works. No codes. No resets. No friction. This is Phi Passwordless Authentication.

Phi removes the weakest link in security: the password itself. It uses cryptographic keys bound to the device, verified by protocols like WebAuthn and FIDO2. Authentication happens instantly, with no secret for attackers to steal or phish. Session integrity is preserved end-to-end.

Implementation is direct. Phi connects to your application through standards-based APIs. A keypair is generated on the user’s device. The private key never leaves local storage, while the public key is registered with your server. When the user signs in, Phi verifies a signed challenge from the device before allowing access. This workflow eliminates brute-force attacks, credential stuffing, and password database breaches.

Performance is high. Authentication occurs in milliseconds, even at scale. Integration is straightforward for web, mobile, and desktop. Since credentials are tied to physical hardware or biometrics, user experience improves while attack surface shrinks.

For compliance, Phi aligns with modern security frameworks and privacy laws. By removing passwords, sensitive personal identifiers are not stored or transmitted, reducing risk during audits and breach investigations.

Upgrading from legacy login systems to Phi Passwordless Authentication cuts costs on password resets, shrinks onboarding friction, and raises trust in your product. The result: stronger security with fewer moving parts.
