What is the difference between YubiKey and Security Key by Yubico?

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.

The Security Key by Yubico is the more affordable option that supports FIDO2/WebAuthn and FIDO U2F protocols only. Some common services that use these are Google and Microsoft accounts, Dropbox, X, Coinbase and 1Password.
