Yubico Security Key C NFC

The Yubico Security Key C NFC is a hardware-based authentication device designed to provide phishing-resistant multi-factor authentication (MFA). It is a core product of Yubico, a global leader in cybersecurity standards. The device supports various protocols including FIDO2, WebAuthn, and U2F, allowing users to secure their online accounts with a physical touch.

Originally founded in 2007 by Stina and Jakob Ehrensvärd in Stockholm, Sweden, the brand has since expanded globally. Yubico maintains a high standard of security by controlling its entire supply chain and manufacturing its keys exclusively in Sweden and the United States. This geographical proximity to its main offices ensures rigorous oversight of the production and programming processes.

In September 2023, Yubico went public on the Nasdaq First North Growth Market in Stockholm through a merger with the Swedish investment company ACQ Bure. As of 2026, Yubico AB remains the ultimate owner and operates as a publicly-traded entity, continuing its mission to set the gold standard for secure digital identity protection worldwide.
