Where/how to get a two-factor authenticator that works everwhere?

23July2018.
Where to get a 2-factor authenticator that
works on lap top pc with W10 upgrade, and
on/together with a cellphone (there are internet
somewhere there inside the phone, but I never
used it).- I know you have TOPT/HOPT, DUO/DuoPush,
winauth, Azure, Google authenticator, HMAX, RFC
authenticators, U2F, 1password, Yubikey etc.
But I would like to manage log-ins without a smartphone.
The 2-factor log-in (text-code via phone) on Coinbase stopped
working. On a cryptocurrency exchange you couldn`t do
anything without a U2F.
