Yubico YubiKey 5C NFC FIPS USB-C Security Key for Two Factor Authentication (2FA) & Passwordless Login, FIDO2/WebAuthn, U2F, OTP, Smart Card (PIV) & OpenPGP – NIST FIPS 140-2 Certified Hardware Security Key

The YubiKey 5C NFC FIPS is a high-security hardware authentication key designed to protect digital identities, enterprise systems and government infrastructure. As cyber threats such as phishing attacks, credential theft and account takeovers continue to increase, organizations require stronger authentication solutions beyond traditional passwords. The YubiKey 5C NFC FIPS provides a reliable hardware-based security solution that enables strong multi-factor authentication and passwordless login. This security key is validated to the FIPS 140-2 standard, which is a U.S. government cryptographic security certification required by many government agencies and regulated industries. The device is validated at Overall Level 2 with Physical Security Level 3, ensuring that it meets strict compliance requirements for high-assurance authentication environments. The YubiKey 5C NFC FIPS features both USB-C connectivity and NFC capability. The USB-C interface allows direct authentication on modern laptops, desktops and tablets, while NFC tap authentication allows secure login on compatible smartphones. This flexibility enables users to authenticate securely across both desktop and mobile environments. The device supports multiple authentication protocols including FIDO2/WebAuthn, FIDO U2F, Yubico OTP, OATH-TOTP, OATH-HOTP, Smart Card (PIV) and OpenPGP. This broad protocol support allows the key to work with thousands of websites, applications and enterprise identity systems. Organizations can secure employee accounts, cloud platforms, VPN access and administrative systems using a single authentication device. One of the major benefits of the YubiKey 5C NFC FIPS is passwordless authentication. Using the FIDO2 standard, users can log into supported services without entering a password. Authentication is completed by inserting the key into the device or tapping it via NFC and touching the sensor. This method uses secure public-key cryptography and ensures that private keys never leave the hardware device, making it extremely resistant to phishing attacks. The YubiKey is designed for durability and reliability. It is constructed using glass-fiber reinforced plastic and engineered to withstand daily use. The device is water resistant, dust resistant and crush resistant, ensuring consistent performance in professional environments. The compact design allows it to be easily attached to a keychain so it can be carried wherever secure authentication is required. Compatibility is another key advantage of the YubiKey ecosystem. The YubiKey 5C NFC FIPS works with major operating systems including Windows, macOS, Linux, ChromeOS, Android and iOS. It integrates with widely used services such as Google accounts, Microsoft accounts, AWS, Salesforce and many password managers. Millions of users and organizations worldwide trust YubiKey hardware security keys to protect digital accounts and sensitive information. By combining FIPS-validated cryptographic security, strong authentication protocols and a durable hardware design, the YubiKey 5C NFC FIPS provides one of the most secure authentication solutions available for modern enterprise and government environments.
