WebAuthnLinux sɣur Samveen

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.
