Yubico was founded in Sweden 2007 with the mission to make secure login easy and available for everyone. In 2011, Stina, CEO & Founder, and Jakob, CTO, moved to Silicon Valley to make the dream happen. In close collaboration with the leading internet companies and thought leaders we created native support for our security keys in the major online platforms and browsers, enabling a safer internet for billions of people.
A global authentication leader
Our team is located in 7 countries, and our security keys, manufactured in Sweden and USA, have won the trust of the largest enterprises and millions of users across the globe. We are a privately held company, backed by renowned Swedish and US investors, and have grown profitably for the past 6 years.
Security keys for users and servers
The company’s core invention, the YubiKey, is a small USB and NFC security key securing access to any number of IT systems and online services. To protect secrets on servers, we also created the YubiHSM, the world’s smallest hardware security module. For easy integration with any IT system, we offer developers open source servers, support and hosted validation services.
A decade of standards innovation
Yubico pioneered the design of the first one-time password authenticator to work with a simple touch and with no client software, and we made it compatible with the open authentication standard OATH. We then further secured and simplified the PIV smart card standard by adding touch-to-sign and built-in attestation. And in close collaboration with Google and Microsoft, we co-created the FIDO Universal 2nd Factor (U2F) and FIDO 2 open authentication standards. Our work has been contributed to open identity standards organizations W3C, IETF, FIDO Alliance and OpenID.
The origin of our brand
We named our first product the YubiKey, with the vision of enabling your ubiquitous key to securely access any number of IT systems. In Japanese, the word “yubi” means “finger”, and by touching the YubiKey with your finger you verify your human presence, and that you are not a remote hacker. Our green logo reflects a growing team, providing IT access keys, enabled by open standards, and with respect for people and the environment.

Cryptographic module validation for YubiKey
Cryptographic module validation testing is performed using the Derived Test Requirements [DTR] for FIPS PUB 140-2, Security Requirements for Cryptographic Modules. The DTR lists all of the vendor and tester requirements for validating a cryptographic module, and it is the basis of testing done by the CST accredited laboratories.
