HyperFido - FIDO U2F Security Key

This HyperFIDO U2F key is small enough to keep in your pocket or purse at all times and never worry about it. It worked great after getting a fast reply from HyperSECU support about the linux udev rules needed (I don't use windows). I had it set up very quickly with Google services and it worked flawlessly. Hopefully, more services will support U2F in the future.

If you are wondering, here are the udev rules their awesome support recommended. I created a file /etc/udev/rules.d/96-hyperfido.rules and used the first example below because thankfully, I do not have to deal with systemd. If you are unfortunate enough to have to use systemd, please use the second example.
