YubiKey 5 is our most versatile security key supporting authentication to a wide range of services and applications using not only FIDO protocols but also OTP, OATH and Smart card/PIV. It also comes in additional form factors incl. Lightning and Nano, and can be used with the Yubico Authenticator app.
