FIDO U2F is an emerging open authentication standard, with built-in support in platforms and browsers. U2F breaks the public authentication matrix with high security, removing the complexity of drivers, specialized client software and the traditional costly CA model. With FIDO U2F, a single YubiKey 5 NFC supports an unlimited number of online services, without user information or encryption keys shared by the service providers. The U2F protocol reached an important milestone in June 2015 with new transport protocols that support mobile devices. U2F works on mobile devices with NFC – Google Authenticator v4.44 and GitHub have both implemented the new transport protocol in December 2015.
