The FIDO U2F Security Key by Yubico is a specially designed YubiKey, relying on high-security, public-key cryptography. Durable and conveniently sized, just slide it out of its protective sleeve, insert it into any USB port, and it works with any website that supports the FIDO U2F protocol, such as Facebook, Google’s Gmail, Google Cloud and G Suite, GitHub, Dropbox, and Dashlane. And all it takes is a simple touch of a button!
Each Security Key has an individualized secure chip which performs cryptographic functions triggered by a simple touch of the key. You never see the details, but behind the scenes FIDO U2F Security Key provides a unique public and private key pair for each application it protects. Only those keys can correctly complete the cryptographic challenge required for login.
The secure chip is of the same class as those used in SIM Cards, electronic passports, military electronic IDs and chip-and-pin credit cards. Like those devices, the chip is specially “hardened” so it’s extremely difficult to steal the secrets hidden inside. The secrets contained in the Security Key belong to the end-user exclusively and are never transferred, copied or stored by a service provider or any other application provider.
This is not a biometric device, instead it uses a capacitive sensor activated by the small bit of electricity the human body naturally produces.
