Feel free to suggest a workable 2FA.  Personally, I use a Yubikey where I can.
Oath seems to be a reasonable approach for technically minded people, but I'm
not sure that it scales well to the people who own the long tail domains in the
40 million .coms.   I can get oathtool to behave the way I want, but I'm not
sure the owner of joes-bait-tackle-and-gunshop.com will be able to deal with

Unless you get it down to the SMS "wait for a msg, type in the 6 digit number"
level, it's going to be a tough start...
