The Authentication Layer Your Enterprise Was Missing
Trustaige is a passwordless identity platform built on FIDO2/WebAuthn standards. It replaces the shared-secret model with asymmetric cryptography that keeps the secret on the device and off the wire.
From Shared Secrets to Cryptographic Proof
Every password-based system relies on the same fragile premise: both the user and the server know the secret. The user sends the password across the network. The server stores a copy. If either side is compromised — through phishing, interception, or a database breach — the identity is stolen.
Trustaige operates on a fundamentally different model. When a user enrolls, their device generates a cryptographic key pair. The private key is locked inside the device's secure hardware. It never leaves. The public key is sent to the server. It's useless on its own — it can verify a signature, but it can never produce one.
At login, the server sends a random challenge. The device signs the challenge with the private key, unlocked by the user's biometric. The server verifies the signature with the public key. No password crosses the network. No secret is stored on the server. Even if the server is fully breached, attackers walk away with public keys that cannot authenticate anything.
This is not incremental improvement. This is a different category of security.
Standards, Not Proprietary Lock-In
Trustaige is built on open, interoperable standards maintained by the organizations that govern the web.
FIDO2
The umbrella specification maintained by the FIDO Alliance, unifying the browser-side and device-side protocols into a single passwordless authentication framework.
WebAuthn (W3C)
The Web Authentication API that allows any website or web application to request strong
authentication from the browser using navigator.credentials.
CTAP
Client to Authenticator Protocol — connects the browser to authenticator hardware, whether that's a built-in biometric sensor or an external security key over USB, NFC, or Bluetooth.
Passkeys
The consumer-friendly evolution of FIDO credentials. Passkeys can sync across device ecosystems via iCloud Keychain, Google Password Manager, or credential managers. For high-security environments, Trustaige can enforce device-bound keys that do not sync.
This means no vendor lock-in. Trustaige works with the browsers, operating systems, and devices your organization already uses.
