it appears like the only differences between YubiKey 4 and Yubikey 5 NFC is i) the addition of NFC and ii) the addition of FIDO 2 support
The differences between Yubikey NEO and YubiKey 5 NFC appear to be i) The addition of docker login support (?!); ii) FIDO 2; iii) RSA 4096 (PGP) support and iv) ECC p384 (not in PGP) support.
With that in mind.... how widely is FIDO2 deployed? I haven't yet found a two factor app supporting app/site that doesn't support my Yubikey 4.
