2FA as such? No, it should be supported everywhere that auth is important. Fido U2F and TOTP. Doxxing/insecure (SMS/e-mail) and inaccessible (Google/Apple required)? 110%. Sick of it. More often than not that these are required I'm certain that "2FA" and "for your security" are just pretexts to be able to tie accounts to meat-space individuals. If you are talking about TOTP and want some centralized solution where you're OK with ceding some control, it exists. Authy seems to be the most popular. I'm sure there are other options where you can get it synced between your smartphone and browser extensions, if that is what you prefer.
