The Immurok is an open-source wireless fingerprint scanner compatible with macOS, Linux, and Windows

The Immurok is an open-source wireless fingerprint authenticator designed for macOS, Linux, and Windows computers. Unlike traditional third-party fingerprint readers that struggle with macOS compatibility, the Immurok bypasses these restrictions by emulating a Personal Identity Verification (PIV) smart card. This allows users to unlock their screens, authorize sudo commands, and sign Git commits with a single touch. Built with an aluminum alloy chassis resembling a miniature Mac Studio, the compact device weighs 40 grams and connects wirelessly via Bluetooth Low Energy (BLE) 5.4. It features a WCH CH592F RISC-V microcontroller and stores all cryptographic data locally on the hardware. The device can secure up to 5 fingerprints, 32 SSH keys, 128 TOTP secrets, and 50 API keys. For physical security, the Immurok includes a tamper-detection mechanism that automatically wipes internal data if the casing is opened. It offers up to three months of standby battery life and recharges via USB-C. The project is fully open-source, with schematics and companion app code hosted on GitHub.

Worth noting

  • The Immurok is launching via a Kickstarter crowdfunding campaign, meaning delivery timelines and final production quality are subject to typical crowdfunding risks.
  • The device's lightweight design (40g) can cause it to slide around on a desk if connected to a rigid USB-C cable.
