QuantumAuth Bridge

Connects web apps to the local QuantumAuth client.

QuantumAuth Bridge QuantumAuth Bridge enables secure, passwordless authentication for websites that integrate the QuantumAuth SDK. It acts as a secure bridge between your browser and the local QuantumAuth Client running on your device, allowing web applications to request TPM-backed and post-quantum cryptographic signatures without exposing private keys. All sensitive cryptographic operations occur locally on your device, backed by trusted hardware such as a TPM, Secure Enclave, or supported hardware security module. Key Features 🔐 Hardware-backed authentication Uses TPM, Secure Enclave, or supported hardware modules for strong device-bound identity. ⚡ Instant cryptographic signing Enables fast, secure signing for modern web authentication and wallet workflows. 🛡 Phishing-resistant by design No passwords, recovery codes, or secrets are ever exposed to websites or servers. 🌐 Seamless web integration Works with any web application built using the QuantumAuth SDK. 🧩 Lightweight & privacy-preserving No tracking, no analytics, and no background data collection. Why install this extension? Websites that support QuantumAuth rely on this extension to communicate with your local QuantumAuth Client. Without the extension: The browser cannot access TPM-backed keys Web apps cannot request secure signatures Hardware-backed authentication is not possible The extension only activates when a supported website explicitly requests authentication. Privacy & Security This extension does not collect, store, or transmit personal data Private keys never leave your device All cryptographic operations occur locally via your QuantumAuth Client Communication is limited to approved requests initiated by the user Important Note This extension requires the QuantumAuth Client to be installed and running locally on your device.
