The YubiKey provide a simple and intuitive authentication experience that users find easy to use, ensuring rapid adoption and organizational security. FIDO2 supports not only today’s two-factor authentication but also paves the way for eliminating weak password authentication, with strong single factor hardware-based authentication. The YubiKey 5 Series helps organizations accelerate to a passwordless future by providing support for the FIDO2 protocol. Users have the broadest options for strong authentication including not only two-factor authentication, but also support for single factor passwordless login and multi-factor authentication in conjunction with user touch and PIN. It offers multi-protocol support including FIDO2, Yubico OTP, OATH HOTP, U2F, PIV, and Open PGP. The YubiKey offers superior security by combining hardware-based authentication and public key cryptography to effectively defend against phishing attacks and eliminate account takeovers. The key lets you log in to many well-known websites and apps, including Gmail, YouTube, Twitter, Dropbox, Office 365, and Xbox Live.The YubiKey 5 Series is a hardware based authentication solution that provides superior defense against phishing, eliminates account takeovers, and enables compliance requirements for strong authentication. No matter how you connect it to your PC, the Security Key NFC supports the FIDO U2F and FIDO2/WebAuthn authentication standards, which isn't surprising, as Yubico contributes to both.

That's still cheaper than Google's Titan USB-C/Security Key, which is $35-if you can find it in stock.

The Security C NFC costs five dollars more than the USB-A option ($29 versus $24). Hardware authentication company Yubico is addressing that need with an inexpensive security key that allows logins via USB-C-or with just a tap of the key to a PC or phone.

So security keys that serve as a form of multi-factor authentication or passwordless login need to play well with the port. The European Union even wants to force the use of USB-C. Because of its power delivery, high transfer rates, and Thunderbolt capabilities, USB-C has become ubiquitous on modern devices.
