I bought some Yubikey standards back in 2014 and they were $25 apiece. The Yubikey 5 NFCs I got 4 years later were $45 apiece, but had NFC and did more stuff. They released some U2F-only yubikey security keys that I thought were $20 but I am not sure (they were blue, and cheap). Now these, which the site suggests can only do U2F/Webauthn with fingerprint, are $80. I think it's cool to have a portable fingerprint-secured webauthn token, but it's disappointing to see them so expensive. I wonder if this is the long-term price, or if they are more expensive temporarily due to supply chain issues or something like that. Or, maybe they are substantially cheaper in bulk.
