Introducing Soft U2F, a software U2F authenticator for macOS

In an effort to increase the adoption of FIDO U2F second factor authentication, we’re releasing Soft U2F—a software-based U2F authenticator for macOS.

Soft U2F currently works with Google Chrome and Opera’s built-in U2F implementations, as well as with the U2F extensions for Safari and Firefox.

When a site loaded in a U2F-compatible browser attempts to register or authenticate with the software token, you’ll see a notification asking you to accept or reject the request. You can experiment on Yubico’s U2F demo site:

And as of today, you can download the Soft U2F installer and configure it for use with your GitHub account.
