The YubiKey 5C NFC is a hardware security key that provides strong two-factor, multi-factor, and passwordless authentication. Supporting USB-C and NFC, it works across laptops and smartphones, making it versatile for both enterprise and personal security. Unlike typical IoT gadgets, it is purpose-built for identity protection and uses a secure element microcontroller to resist tampering. Its firmware is not upgradable by design, reducing attack vectors.
