Two-factor authentication made easy
Two-factor authentication (2FA) is also referred to as two-step verification (2SV). It adds an extra layer of security to your account that you, and only you, can access in order to prove your identity.
Millions of people use YubiKeys for 2FA because they’re the easiest to use, super secure, and affordable. Plug in your YubiKey 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.

Different services use different types of security protocols. YubiKeys are capable of performing multiple protocols, so you can use the same key for almost an unlimited number of services.
