I suspect you can use any yubikey that supports passcodes. It looks like they also allow/require pin encryption.

They have new bio keys.
I guess my question is which hardware is being used.

Disclaimer: I had a yubikey many years ago, I haven't used the new ones

no.

UbiKey is just a keyboard that always spits the same text out. it only has one button, and so u plug it in and press the button and it spits out whatever string is stored on it.
