QuantumAuth Bridge is a Chrome extension designed to facilitate secure, passwordless authentication for web applications utilizing the QuantumAuth SDK. This tool acts as a connection between your browser and the local QuantumAuth Client on your device, enabling requests for cryptographic signatures without exposing sensitive private keys. Key features include hardware-backed authentication through trusted modules like TPM and Secure Enclave, instant cryptographic signing capabilities, and a design that inherently resists phishing attempts by ensuring that no passwords or recovery codes are ever revealed to external sites.

This extension integrates seamlessly with any web application that supports the QuantumAuth SDK, ensuring that all sensitive cryptographic operations are conducted locally on your device. It prioritizes user privacy by avoiding tracking, analytics, or background data collection. The extension activates only upon requests from supported websites, making it a lightweight solution for secure web authentication.
