Security Keys Authentication




Supported in 2.10.0+

This feature is only available in the Windows Workforce Access Client 2.10.0 and above

This document describes how to enable Smartkeys (Security Keys) enrollment and authentication for HYPR Workforce Access Client.





A Personal Identification Number (PIN) is a set of characters used to unlock the smart card for use. For example, the Windows operating system allows numbers or letters for a PIN. Mac OS only supports numbers for PINs. The PIN is a decentralized secret the user should not share. The PIN is bound and used to unlock an authenticator. In the case of a hardware security key, such as a Yubico YubiKey, the PIN resides on the YubiKey and unlocks the authenticator that uses public/private key encryption to perform authentication.


A PIN Unblocking Key (PUK) is a code that is used by users or applications to reset a PIN that has been lost, forgotten, or locked because of too many failed attempts. The PUK is part of the PIV standard that the YubiKey follows.


Personal Identity Verification or frequently associated together as a "PIV Card" is commonly the reference to United States Federal smart card that contains the necessary data for the cardholder to be granted to Federal facilities and information systems and assure appropriate levels of security for all applicable Federal applications. It is also a general means of reference for Smartcards and associated protocols & standards used for authenticating users securely.
