6/21/2023 0 Comments Fido2 u2f![]() ![]() I know FIDO2 is what allows "Universal Second Factor" (U2F) devices like YubiKey USB dongles to work as a physical multifactor authentication (MFA) devices. I seem to recall that the new Passkeys feature that Apple announced at WWDC 2022 to be in Apple's Fall 2022 OS updates (iOS 16, macOS 13 Ventura, Safari 16, etc.) seems to be built, at least in part, on industry standard authentication schemes such as FIDO2. To put it more precisely, can Apple's new Passkeys feature allow Apple devices to basically use their built-in Secure Enclaves like built-in U2F devices, replacing external USB security dongles like YubiKeys? So your two factor authentication (2FA) factors become "something you have" (an Apple device with your Passkey private keys in the Secure Enclave), and "something you are" (your face/fingerprint biometrics)?
