One key. Two form factors. The Standard and Nano deliver a one-time passcode (OTP) with a simple touch of a button. No SMS-like passcodes to retype from one device to another. Our most basic YubiKey identifies itself as an external keyboard, which eliminates the need for client software or drivers. The nearly indestructible key holds tight onto its secrets, and its design ensures it will never be a vector for viruses or malware, just like the rest of our YubiKeys.

How it works

Two-factor authentication is becoming the go-to technology for protecting your applications and accounts from the epidemic of password thefts. YubiKey thwarts hackers with a unique hardware device that plugs into a USB port. Elegant in design, simple in operation.

The YubiKey

The YubiKey is a second authentication method based on a unique physical token which cannot be duplicated or recorded, providing a credential based on something only an authorized user possesses. Used with a standard username and password, the YubiKey provides strong, two-factor authentication to any site, service or application.

Any System, Any OS

Any computer which can use a USB keyboard can also use the YubiKey, regardless of the computer hardware, operating system or system drivers. The YubiKey AES Key information can never be extracted from a YubiKey device – only programmed to it. Further, only the YubiKey security-related codes are directly read from the YubiKey when in use. No transfer of non-security related data means the YubiKey will never be a vector for viruses, Trojans, or other malware.

Durable, Rugged, Secure

The YubiKey hardware itself consists of injection-molded plastic encasing the circuitry which makes up the YubiKey, while the exposed elements consist of military-grade hardened gold. The YubiKey does not contain an internal battery or any moving parts – meaning that a YubiKey will never stop functioning due to lack of power, mechanical issues, or internal damage due to exposure.

FIPS certification

The YubiKey Standard and YubiKey Nano have been granted FIPS 140-2 certification (#2267), validating that the design and security functionality meets the highest security standard.
