The YubiKey 4 is the strong authentication bullseye the industry has been aiming at for years, enabling one single key to secure an unlimited number of applications. Yubico’s 4th generation YubiKey is built on high-performance secure elements. It includes the same range of one-time password and public key authentication protocols as in the YubiKey NEO, excluding NFC, but with stronger public/private keys, faster crypto operations and the world’s first touch-to-sign feature. With the YubiKey 4 platform, we have further improved our manufacturing and ordering process, enabling customers to order exactly what functions they want in 500+ unit volumes, with no secrets stored at Yubico or shared with a third-party organization. The best part? An organization can securely customize 1,000 YubiKeys in less than 10 minutes. For customers who require NFC, the YubiKey NEO is our full-featured key with both contact (USB) and contactless (NFC, MIFARE) communications.




The YubiKey 4 and YubiKey 4 Nano can be used for securing access to a wide range of applications, including remote access and VPN, password managers, computer login, FIDO U2F login (Gmail, GitHub, Dropbox, etc), content management systems, and much more.

FIDO U2F is an emerging open authentication standard, with native support in platforms and browsers. U2F breaks the mold for high security public key authentication, removing the complexity of drivers, specialized client software, and the traditional costly CA model. With FIDO U2F, one single YubiKey 4 or YubiKey 4 Nano supports any number of online services, with no user information or encryption keys shared between the service providers.
