The ePass FIDO2-NFC Security Key, model K40 Plus provides a secure, phishing-resistant authentication scheme to web applications. Unlike the traditional second-factor authentication devices, FIDO Security Keys provides a much more convenient solution to add another security layer on traditional password authentication scheme.

A single key can protect unlimited accounts across multiple websites. The public key infrastructure behind FIDO provides strong cryptographic protection against attacks. Each application will be assigned an individual key pair to preserve user’s privacy.

The embedded high-performance NXP security element also helps to provide random and strong key pairs generated for FIDO authentication and protect user's private information against multiple security threats.

Supports PIV credential authentication for logical and physical access for Government employees and contractors or privileged users to access servers, networks, and applications. 

What is PIV?

A Personal Identity Verification (PIV) credential is a US Federal governmentwide credential used to access Federally controlled facilities and information systems at the appropriate security level.

PIV credentials have certificates and key pairs, pin numbers, biometrics like fingerprints and pictures, and other unique identifiers. When put together into a PIV credential, it provides the capability to implement multi-factor authentication for networks, applications, and buildings.

This is the process of creating and using a government-wide secure and reliable form of identification for federal employees and contractors, in support of HSPD-12, Policy for a Common Identification Standard for Federal Employees and Contractors.
