When Yubico released its Authenticator app for iOS, it only worked with the YubiKey 5Ci, a model that can be plugged in via the Lightning port. This update means you can also use the YubiKey 5 NFC with the authenticator to sign into apps and services simply by tapping the key at the top of an iPhone 7 or later.
