This is a fork of that uses the U2F JS API v1.1

To use this to test U2F support in Firefox using its built-in software token, do the following:

  1. Open the Firefox advanced preferences in about:config.
  2. Search for "webauth"
  3. Enable (value=True) these two:
    • security.webauth.u2f
    • security.webauth.u2f_enable_softtoken
  4. Reload this page and click buttons!




Facet ID to use.
