HyperFIDO Bio is a hardware security key with an integrated fingerprint sensor, designed for biometric-based authentication. This page specifically covers how to set up and manage the device on macOS and Linux using the Chrome browser. Key management tasks available through Chrome's built-in security key manager include: - PIN creation and modification - Fingerprint registration and removal - Full device reset Setup workflow: 1. Access Chrome Settings → Privacy and Security → Security → Manage Security Keys 2. Create a PIN before registering fingerprints (required prerequisite) 3. Register one or more fingerprints by touching the sensor repeatedly until fully captured 4. Optionally name each registered fingerprint for identification The device requires physical interaction at each management step — the user must insert the key and touch the fingerprint sensor when prompted. Multiple fingerprints can be registered on a single device, and individual fingerprints can be selectively removed. A full reset option is available to clear all stored data and PIN from the key, useful when the PIN is forgotten or the device needs to be wiped. For Windows users, management is handled through Windows 10 account settings rather than the Chrome browser.
