A YubiKey is a small device that you register with a service or site that supports two-factor authentication. Two-factor authentication means that each time you log in, the service will request proof that you have your YubiKey in addition to your regular username and password.

Yubico products work with hundreds of services and applications for individuals, businesses, and developers. View here our featured solutions for businesses, plus links to technical and integration documentation.


YubiKey Nano is the world’s smallest one-time password token, smaller than a SIM card, providing the same authentication and security properties of a standard YubiKey. It is designed to stay inside the USB-slot once inserted, as it cleanly fits inside of a USB port.
