All-in-one configurable security key
Different services use different types of security protocols. YubiKeys are capable of performing multiple protocols, so you can use the same key for almost an unlimited number of services.
In 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
The 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.

The skinny on universal 2n factor (U2F)
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 supports any number of online services, with no user information or encryption keys shared between the service providers. Learn more about FIDO U2F.
