I am looking forward to FIDO being more popular since 2FA has the flaw that both sides need to keep the seed code encrypted and secure. There has been cases where the website did a poor job with this security.
FIDO uses a different process that supposedly eliminates this problem. Alas i do not know the tech behind it.
FIDO doesn't work on mobile, so you wouldn't be able to login to any sites using it while on your phone.
Well that sucks. Thanks for the info.
