The YubiKey prevents unauthorized access to user accounts with unmatched security, usability, and affordability. Proven and trusted with the world’s largest brands – including Google, Facebook, and Saforce.com employees – and millions of global users.
The YubiKey is a hardware authentication device manufactured by Yubico that supports one-time passwords, public-key encryption, and authentication. It is the Universal 2nd Factor (U2F) protocol developed by the FIDO Alliance. It allows users to securely log in to their accounts by emitting one-time passwords or using a FIDO-based public/private key pair generated by the device. YubiKey also allows for storing static passwords for use at sites that do not support one-time passwords. Facebook uses YubiKey for employee credentials, and Google supports it for both employees and users. Some password managers support YubiKey.
