Millions of people use YubiKeys for 2FA because they're the easiest to use, super secure, and affordable. Plug in your Yubico Yubikey 4C Nano USB C Authentication Device and tap it to log in to your computers, networks, and online services. Keep one on your keychain with the key to your house/car, and a second YubiKey in a safe place as a backup.
