Chiave di sicurezza YubiKey Yubico 5C Nano FIPS 2048 bit RSA

The YubiKey Yubico 5C Nano FIPS is a compact, hardware-based security key designed to provide strong authentication for accounts and services. FIPS 140-2 validated (Overall Level 2, Physical Security Level 3) and supporting 2048-bit RSA cryptography, this key defends against phishing and account takeovers while meeting NIST SP800-63B authenticator assurance level AAL3. It is compatible with Windows, macOS, Chrome OS and Linux and supports multiple authentication protocols including Yubico OTP, OATH HOTP, U2F, PIV and OpenPGP.

Advantages

The YubiKey 5C Nano FIPS delivers hardware-backed security without batteries or network dependence, offering fast, reliable authentication up to several times quicker than OTP or SMS methods. Its small form factor makes it convenient to carry while maintaining enterprise-grade cryptography (2048-bit RSA) and FIPS 140-2 validation for regulated environments. Broad protocol support reduces integration complexity and helps lower helpdesk incidents related to password reset and account lockout.

Suitable for

• Protecting Google, Microsoft and other cloud accounts
• Secure access to corporate laptops and desktops (Windows, macOS, Linux)
• Compliance-focused deployments in government and regulated industries
• Services and applications supporting FIDO U2F/UAF, PIV or OpenPGP

How to use

Insert the YubiKey 5C Nano FIPS into a USB-C port or use device-specific methods to register the key with your account or service. During account setup, choose the hardware security key or security key option and follow the provider’s prompts to register the device. For systems using PIV or OpenPGP, follow the administration tools’ steps to generate or import keys and configure authentication policies.

Recommendations

Store a spare registered YubiKey in a secure location to avoid account lockout if the primary key is lost. Ensure service providers support the required protocols (AAL3 / FIPS) and follow organizational policies for key provisioning and lifecycle management.
