When will duo support u2f keys in Firefox? A yubikey has worked in firefox for months using an add-on, and with firefox 57 released a few weeks ago the u2f support is native; it works with many 2fa systems but not yet with duo.
the current message is:
“Your browser does not support U2F token authentication.
Please use a U2F compatible browser.”
i have heard of people using a user-agent switcher to spoof chrome, then supposedly duo will work with u2f keys, but i have not tested this and prefer not to use this regularly.
