About the Company

Yubico

Two-factor authentication hardware key provider

Yubico provides physical security keys, called YubiKey, to enable strong two-factor authentication for individuals and organizations. The keys are plugged in or tapped to prove the user’s identity, and they work with multiple standards (FIDO/U2F, smart card, and one-time passwords) while offering developer tools to integrate into apps and services. Compared with software-only methods, Yubico offers multiple form factors, broad platform compatibility, and enterprise support to serve various security needs. Its goal is to make login more reliable and protect data by making strong authentication easy to deploy across many industries.
