A hardware update is an update to the firmware on your Bitkey device. Firmware is the secure software that runs on your device and controls how it functions.
Firmware updates (also called FWUPs) are designed to improve your device by providing:
- Enhanced security
- Improved performance
- New features (when available)
Like updating apps on your phone or computer, firmware updates help keep your Bitkey device up to date.
To keep your device secure and working as expected, update your hardware whenever an update is available.
