I bought this to try and set up a USB security key for MFA authentication (similar to Yubico's keys) using Google's open source OpenSK programming kit. It worked great for that purpose, but had to switch to using OSX to be successful. I first tried using WSL2 on Windows 10 but quickly found that it didn't recognize the USB device (an open issue with WSL). Since the solution has already been tested with OSX, I decided to switch to my MBPro to get the key working. (I also had to use a USB-C to USB-A adapter to install the dongle.) Very happy with the quality and low price so far. BTW, there are some basic setup instructions on the Feitian website, but I don't see that key in their current product line.
