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.

Our newest 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 (released 11/18/14). 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.

Where you can use YubiKey NEO or NEO-n

The YubiKey NEO and NEO-n can be used for securing access to a wide range of applications, including remote access and VPN, password managers, computer login, Gmail login, content management systems, popular online services, and much more. Find out more about the range of open source and enterprise solutions on our YubiKey for Business and YubiKey for Individuals pages.

FIDO U2F breaks the mold for high security public key hardware devices, removing the complexity of drivers, clients software and the traditional costly CA model. With FIDO U2F, one single YubiKey NEO or NEO-n can be used with any number of online services, with no user information and encryption keys shared between the service providers. In the near future, large scale online services will support FIDO U2F, enabling users to own and control their single and secure online identity for any number of services. Please note, current U2F standards do not support NFC for mobile devices. For more information, you can access the full U2F Specifications on the FIDO Alliance website.

Can I use one NEO with LastPass and Gmail along with other apps?

Yes! The same YubiKey NEO or NEO-n can be used for a multitude of apps at the same time, including LastPass as well as Gmail. The YubiKey NEO can be configured for U2F and other modes using the NEO Manager.

How does the NEO work with my mobile device?

YubiKey NEO has NFC contactless technology capabilities so you can use your NEO on any Android device that supports NFC. U2F is not yet supported over NFC. Please note that the YubiKey NEO-n, in the smaller form factor, does not support NFC.

Can my NEO work over NFC with my iPhone 6?

Not currently, but once Apple opens up support for NFC to third party developers it may be possible. Please subscribe to our bi-monthly newsletter and blog to stay up-to-date on the latest information.

What are my benefits when using the OTP+U2F+CCID configuration?

When using the YubiKey NEO or NEO-n in OTP+U2F+CCID mode, users can access every feature of their device to secure their online accounts. On the same YubiKey, at the same time, users can use U2F to secure their Gmail account, access services like LastPass, as well as secure their communication using applets loaded on their device, such as the OpenPGP applet.

Please visit our applications page to see the many applications and use cases that NEO supports.

Can the YubiKey NEO be used as a Smart Lock device for Android Lollipop?

Yes, the YubiKey NEO can be used as an NFC tag registered for Smart Lock on Android Lollipop devices. For more information, see the Android support page.

Note: Android’s SmartLock features uses a static 7 byte ID, which does not conform to Yubico’s security threshold standards. We recommend users consider this feature a convenience and not a strong authentication replacement.

Can I use my U2F-enabled NEO device to enable strong two-factor authentication for my enterprise?

Any online service or application can integrate with the U2F protocol. One of our key partners, Duo Security, is the first to offer enterprise server solutions supporting U2F. You can learn more about Duo Security and U2F.

How many services can the YubiKey NEO/NEO-n be associated with?

There is no practical limit to the U2F secured services the YubiKey NEO/NEO-n can be associated with. During the registration process, the key pairs are generated on the device (secure element) but the key pairs are not stored on the YubiKey NEO/NEO-n. Instead, the key pair (public key and encrypted private key) are stored by each relying party/service that initiated the registration. Therefore, this approach allows for an unlimited number of services to be associated with the YubiKey NEO/NEO-n.

How can I setup my Linux instance for use with U2F?

We advise everyone to install the Yubikey NEO manager software. The latest version of this software can be found here:

Step 1:

If you have a Yubikey NEO or Yubikey NEO-n, ensure you have unlocked the U2F mode by following these instructions:

  1. If you have a Security Key by Yubico (blue color) U2F is enabled by default (only U2F mode is supported on this product!)

Step 2:
download or create a copy of the file named 70-u2f.rules into the Linux directory /etc/udev/rules.d/.

If this file is already there, please ensure that the content looks like exactly the one provided on (link above).

Save your file. Reboot the machine.

Step 3:
Ensure that you are running Chrome 38 or above. From version 39 of Chrome you will be able to use the Yubikey NEO or NEO-n in U2F+HID mode.

NOTICE: This applies only to Yubikey NEO and NEO-n, the Security Key by Yubico only supports U2F mode enabled by default.

When can I purchase a YubiKey NEO with FIDO U2F or can I upgrade my current NEO?

YubiKey NEO and NEO-n devices have shipped with firmware version 3.3 since Oct. 1, which includes U2F support along with other protocols including Yubico OTP and smart card functionality. YubiKey NEOs are not upgradable based on best security practices. There is a no upgrade policy for our devices since nothing, including malware, can write to the firmware.
