يوبيكو Yubico

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.

Has the capability for 2 identities (“Slots”) when programmed with the Personalization tool. This YubiKey comes with a lifetime subscription for the YubiCloud validation service, pre-configured in identity slot 1 and slot 2 blank. The free personalization tool (for Windows, Mac OS X and GNU/Linux) allows re-configuration for other schemes.
