OpenVPN auth with Fido/U2F via pam-u2f ?

  • Has anyone tried out the Yubico pam module for the Fido U2F protocol?

    Hints on around the web suggest that Yubico will come out with a Bluetooth-enabled version of their 4096-bit Yubikey-4 which would be quite interesting as something that would work both with desktop and mobile devices.

    Only Chrome has it built in as yet but there is a user-contributed plugin for Firefox.
