The immurok is a custom-built, wireless biometric authentication device designed to streamline terminal workflows and system logins for Linux and Mac users by replacing manual password entry with fingerprints.

Key Points

• The device utilizes a WCH CH592F microcontroller for Bluetooth connectivity and an R559S capacitive sensor for local biometric verification.
• It functions as a standard Bluetooth HID keyboard, ensuring compatibility across different operating systems without transmitting sensitive biometric data.
• Linux integration relies on a CLI/TUI application and PAM to manage system logins and sudo terminal commands.
• Mac users can utilize a dedicated menu bar application and PAM integration to handle administrative prompts and lock screen authentication.

Why it Matters

This project offers a practical solution for power users who frequently encounter repetitive password prompts during terminal-heavy workflows. By bringing mobile-style biometric convenience to desktop environments, it demonstrates how custom hardware can effectively bridge gaps in existing operating system security interfaces.
