Yubico YubiKey 5C FIPS 140-3 USB-C Security Key

Add a dedicated USB-C hardware authenticator where users need to prove possession of a physical security key during sign-in. Yubico 101190 identifies the YubiKey 5C FIPS 140-3, a security key variant intended for environments that require the named FIPS 140-3 product designation. Its USB-C connection makes it suitable for current notebooks, desktops, tablets, and other compatible host devices with USB-C ports. A physical authenticator can strengthen access workflows by requiring the user to have the key present in addition to entering account credentials. This approach is useful for administrative access, remote-user authentication, privileged accounts, and organizations standardizing on hardware-backed identity factors. The compact key format also avoids a dependency on a battery or wireless pairing for use at the host connection. Within the YubiKey 5 family, this version is distinguished by its USB-C connector and FIPS 140-3 designation. Select it when the target endpoint uses USB-C and the deployment calls for this specific FIPS-labelled YubiKey 5C variant. Validate application, identity-provider, and endpoint compatibility with the authentication methods configured in the environment before deployment.
