hedgehog, 8 months ago The site likely didn’t support passkeys. But passkeys are basically webauthn passwordless login, and per the yubikey docs they support that. See www.yubico.com/authentication-standards/fido2/ and fidoalliance.org/passkeys/#faq for more info. See also support.apple.com/guide/iphone/…/ios specifically the bit about adding a passkey to a physical key.
