Re: Standardise 2FA
The Yubikeys support most of the 2FA standards that are currently in use (at least, dongle based methods). They are also programmable, so additional methods could be added.
I've been using keys for about 6-7 years for providing 2FA on LastPass and for Microsoft, Google and a few other services. Just holding the key against my smartphone to unlick LastPass is great - worked with my old Lumias and with my Android phones.
