SoftU2F for Window

Introducing Soft U2F for windows - A software implementation for u2f authenticator for Windows.

TL;DR Do I need this software?

Likely No - if you are a normal Windows user

Microsoft will officially implement a FIDO2 authenticator as a feature of Windows Hello to improve the security by going password less

Maybe Yes - if you are interested in Windows Driver/Desktop application development

What is a SoftU2F

If you care about web security, you might have heard of the secure hardware YubiKey as the MFA authenticator for your online account, which brings your credential secuirity to a hardware level. A SoftU2F is a software implementation of the u2f protocol which is being used by YubiKey. It leverages on the operating system security hardware/API and simulates the behavior of a hardware secure key at the OS driver level to provide a secure and convinient approach of MFA authentication.

There is already a macOS version created by Github team years ago: https://github.com/github/SoftU2F
