1Password has that :-) So if you auto-fill on a login page, it will place your username, password, and 2FA codegen into the site's authentication fields. It will not auto-suggest a login if you're not on the site it originated from - which is often enough to cause people to take a second look at the URL (which really helps thwart phishing). Plus, it sends your authentication info to the browser via a secure connection to the 1Password browser extension, so (a) your credentials can't be keylogged, and (b) they never touch the clipboard, so they can't be stolen from there either. But all of that is also true of non-MFA logins from 1Password. So again, I don't see the added benefit of MFA if you're already using 1Password with long random passwords.
