The YubiKey works with hundreds of enterprise, developer and consumer applications, out-of-the-box and with no client software. Combined with leading password managers, social login and enterprise single sign on systems the YubiKey enables secure access to millions of online services.

A single YubiKey has multiple functions for securing your login to email, online services, apps, computers, and even physical spaces. Use any YubiKey feature, or use them all. The versatile YubiKey requires no software installation or battery so just plug it into a USB port and touch the button, or tap-n-go using NFC for secure authentication.

Smart cards are another supported protocol on the YubiKey. The YubiKey identifies itself as a smart card reader with a smart card plugged in so it will work with most common smart card drivers. The YubiKey allows three different protocols to be used simultaneously – PIV, as defined by the NIST standard for authentication; OpenPGP for encryption, decryption, and signing; and OATH, for client apps like Yubico Authenticator
