If you've purchased a FEITIAN FIDO2 device and can't seem to get it working with Linux, Jack Wallen shows you how.
That's fundamentally how FIDO2 works, and there are plenty of companies that make such devices.
After a bit of work and some help from the FEITIAN developers, I was able to get one of the products-the K26 FEITIAN BioPass FIDO2 Biometric Fingerprint USB-C Security Key.
Nowhere in the FEITIAN documentation does it mention having to create a udev rule, which enables the system to identify devices based on their properties, like vendor ID and device ID. Unfortunately, without that rule in place, the device cannot be recognized by Linux.
It's a shame getting such a device working with Linux requires users to jump through hoops they don't have to on other platforms.
