QuantumAuth Bridge από Ian Dorion

QuantumAuth Bridge enables secure, passwordless authentication for websites that integrate the QuantumAuth SDK.

The extension acts as a secure bridge between your browser and the local QuantumAuth Client running on your device. It allows web applications to request TPM-backed and post-quantum cryptographic signatures without exposing private keys.

All sensitive operations are performed locally on your machine, backed by trusted hardware such as a TPM, Secure Enclave, or supported hardware security module.

Key Features

Hardware-backed authentication using device-bound keys

Post-quantum–ready cryptographic signing

Phishing-resistant — no passwords, codes, or secrets leave your device

Works with any website built using the QuantumAuth SDK

Privacy-preserving — no tracking, analytics, or data collection

Why this extension is required

Websites using QuantumAuth rely on this extension to communicate securely with the local QuantumAuth Client.
Without it, the browser cannot access hardware-backed keys or approve secure signature requests.

Privacy & Security

No personal data is collected or stored by the extension

Private keys never leave your device

The extension only forwards explicitly approved authentication requests

Note: This extension requires the QuantumAuth Client to be installed and running locally.
