The [previously used U2F library](https://github.com/fido-alliance/google-u2f-ref-code/) has been deprecated. The new one does not override the browsers `window.u2f` functionality if it is natively supported. It also displays the appropriate errors and falls back nicely in case the browser does not support U2F.
