YubiKey 4 Nano

The YubiKey is the original and leading FIDO U2F authenticator, proven at scale by global enterprises and consumers.

The YubiKey 4 Nano is the smallest USB authentication key. It includes FIDO U2F, strong crypto and touch-to-sign, plus One-Time Password, and smart card functionality.

To authenticate with a FIDO U2F certified YubiKey 4 Nano, the user simply plugs it in, and touches the gold edge. Manufactured in the USA and Sweden, with best practice security processes. YubiKey 4 Nano is crush-safe, water-resistant, and fits nicely in your USB port for semi-permanent installation and convenience.

YubiKey 4 Nano also secures access to a wide range of IT applications, and works out of the box with hundreds of services.


Yubico is the leading contributor to FIDO standards. Its flagship product, the YubiKey, is an innovative USB and NFC authentication key. The product secures access to computers, networks, and services, and is loved by millions in 160 countries, including 9 of the top 10 internet companies.
Founded in 2007 with the mission of making secure login easy and available for everyone, Yubico co-created the FIDO U2F protocol together with Google. And Yubico’s CTO, Jakob Ehrensvard, introduced the concept of an authenticator that works across any number of services, with no shared secrets — which is the core innovation and foundation behind all FIDO standards.
