All 3 mechanisms are native to a yubikey, and do not require yubikey-specific software/drivers to function as they use USB standards like FIDO2, keyboard for HMAC, and PIV/CCID for OpenPGP.
FIDO2 is built-in out-of-the-box, HMAC just requires adding the key to HMAC on slot 1 or 2 (tap vs long-hold key-inputs) using the personalization tool, or using gpg(2) to card-edit for OpenPGP.
None of these require YK software to operate.










Huh, kinda cool. I mean it makes sense too since it’s got that “copying someone’s homework” benefit for updates too.
