NFC Security Key
a single device, the YubiKey NEO has both contact (USB) and contactless
(NFC, MIFARE) communications. It supports one-time password, smart card
functionality, including OpenPGP and PIV, and the emerging FIDO Alliance Universal 2nd Factor (U2F) protocol.
If NFC is not required, or if the smaller Nano form factor is preferred, we recommend customers purchase the YubiKey 4 or YubiKey 4 Nano, our latest generation YubiKey, which include stronger and faster crypto.
Where You Can Use YubiKey NEO
YubiKey NEO 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, popular online services, and much more. Find out
