SoloKeys has open hardware sticks.

But there’s open FIDO2 sticks around. One would be SoloKeys. Then there’s other competitors, though not open.

But if you mean, simple authentication via stick, sure. Or you could do your own thing, watching via udev for the MAC ID, write a file somewhere sensitive and look in your login script if it exists.
