QuantumAuth Bridge

About

QuantumAuth Bridge

QuantumAuth Bridge connects your browser to the QuantumAuth Client, enabling hardware-backed and post-quantum identity for Web3 and modern web applications.

It allows websites using the QuantumAuth SDK to request secure, device-bound cryptographic authorization—without exposing private keys, seed phrases, or passwords.

QuantumAuth is a post-quantum identity protocol, not a traditional wallet or password system.
This extension acts as the secure communication layer between the browser and your local device.

All sensitive cryptographic operations happen locally on your machine, protected by trusted hardware such as a TPM, Secure Enclave, or supported hardware security module.

Key Features

🔐 TPM-sealed private keys
Private keys are generated and sealed in hardware and never leave your device.

🧠 Account Abstraction–ready
Designed for modern Web3 flows, enabling secure authorization without exposing keys to websites.

🛡 Phishing-resistant by design
No passwords, recovery phrases, or secrets are shared with websites or servers.

⚡ Local cryptographic authorization
Web apps can request signatures securely through your device, not through the browser.

🌐 Seamless web integration
Works with any application built using the QuantumAuth SDK.

🧩 Privacy-preserving
No tracking, no analytics, no background data collection.

Why this extension is required

Websites that support QuantumAuth rely on this extension to securely communicate with your local QuantumAuth Client.

Without the extension:

Browsers cannot access TPM-sealed keys

Web apps cannot request secure authorization

Hardware-backed identity is not possible

The extension only activates when a supported website explicitly requests authentication and always requires user approval.

Privacy & Security

No personal data is collected or transmitted

Private keys never leave your device

All cryptographic operations occur locally

Communication is limited to approved, user-initiated requests

Important Note

This extension requires the QuantumAuth Client to be installed and running locally on your device.
