YUBICO YubiKey NEO

The YubiKey NEO is the strong authentication bullseye the industry has been aiming at for years, enabling one single key to secure an unlimited number of applications.
The NEO keys with the 3.3 firmware support U2F + OTP and CCID at the same time on the same key when running Version 39 of the Chrome browser. Users have long sought this multi-functionality, and now it is here.
In a single device, the Yubikey NEO has both contact (USB) and contactless (NFC, MIFARE) communications. It uniquely supports One-Time Passcodes, smart card functionality, including OpenPGP and PIV, and the emerging FIDO Alliance Universal 2nd Factor (U2F) protocol. The YubiKey NEO can be configured for U2F and other modes using the NEO Manager.
