Given the ubiquity of both NFC and USB-C, I feel that this version is the best overall, giving the widest compatibility with the least amount of hassle. The company also sells different versions of this device: with standard USB and NFC with a Lightning connector and USB-C with USB-C only and two Nano versions that you leave permanently connected. It has a USB-C connector on one end, NFC built-in. The Yubikey 5C NFC is a tiny USB device, a little bigger than a coin, that you can fit onto a keychain or keep in your wallet. It’s more secure than using a code generator, works with practically every service and device, and is well priced. This tiny USB-C device can plug into a computer or use NFC with a smartphone, acting as the two-factor authenticator. Generating these one-time codes can be a real pain, which is where the Yubico Yubikey 5C NFC comes in. Two-factor authentication is an essential add-on for any online account, requiring a special one-time code that only you know in addition to a password.

Two-factor security This key generates two-factor authentication codes in a more a secure and phishing-resistant way to an authenticator app.
