The Yubikey Neo is a USB dongle for securing access to a wide range of applications, including remote access software, password managers, or to log onto your PC. In addition, many popular cloud services, such as Gmail and Dropbox, will also work with the Yubikey for two-factor authentication.
But what if you have already blocked off your USB ports with the Lindy USB port blocker? That’s where the nifty NFC capability of the Yubikey Neo comes in — you can authenticate wirelessly with an NFC-equipped laptop or Android smartphone.
