Is there any inexpensive USB-based security keys? I'd love to get one for my Mac and PC but Yubico Nano is $50; I would like two of these, but they are $100 already.
EDIT: I also see Yubico Fido Keys which are $20 each (and $36 for 2). Are there any differences between these and the regular Yubico keys?
