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.
The YubiKey is a hardware authentication device manufactured
by Yubico that supports one-time passwords, public-key encryption and
authentication, and the Universal 2nd Factor (U2F) and FIDO2 protocols
developed by the FIDO Alliance. It allows users to securely log into 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. Yubico also
manufactures the Security Key, a device similar to the YubiKey, but focused on
public-key authentication.
The Yubikey implements the HMAC-based One-time Password
Algorithm (HOTP) and the Time-based One-time Password Algorithm (TOTP), and
identifies itself as a keyboard that delivers the one-time password over the
USB HID protocol. The YubiKey NEO and YubiKey 4 include protocols such as
OpenPGP card using 2048-bit RSA and elliptical curve cryptography (ECC) p256
and p384, Near Field Communication (NFC), and FIDO U2F. The YubiKey allows
users to sign, encrypt and decrypt messages without exposing the private keys
to the outside world. The 4th generation YubiKey launched on November 16, 2015.
It has support for OpenPGP with 4096-bit RSA keys, and PKCS#11 support for PIV
smart cards, a feature that allows for code signing of Docker images.
Founded in 2007 by CEO Stina Ehrensvärd, Yubico is a private
company with offices in Palo Alto, Seattle, and Stockholm. Yubico CTO, Jakob
Ehrensvärd, is the lead author of the original strong authentication
specification that became known as Universal 2nd Factor (U2F).
