About this extension
Code hosted at https://github.com/samveen/WebAuthnLinux.

This extension enables Linux System Integration for WebAuthn/FIDO2. It features a Python-based Native Messaging Host that bridges the gap between the browser and the Linux system's biometric services (via fprintd).

This allows the extension to leverage your laptop's built-in fingerprint reader for user verification events, bypassing the need for external hardware or specific web services.

Key Features
  • Linux Fingerprint Integration: Use fprintd for biometric authentication directly in the browser.
  • Native Messaging Support: Secure communication between the extension and the local system.
  • Multi-Browser Compatibility: Installation script supports Chrome, Chromium, and Firefox.
  • Manifest V3: Modern extension architecture for improved security and performance.
  • Dynamic Security: Uses a unique, dynamically generated 256-bit master key and unique installation salts (no hardcoded secrets).
  • Hardware Agnostic: Designed to bridge system biometrics for development, even on systems where the browser doesn't natively expose the fingerprint reader as a "platform" authenticator.

Quick Setup
  1. System Dependencies: Ensure fprintd and python3 are installed and configured.
  2. Install Native Host: Get the code from https://github.com/samveen/WebAuthnLinux/ , review the native setup script and then run it:
    bash
    cd native
    ./install.sh --firefox
  3. Install the extension.
