Where does this even come from, passwords are increasingly insecure and adding another factor, especially authenticator codes, doesn't even require you to give up a single new piece of personal information. The entire thing is just adding a local code that your program of choice remembers and uses to generate the one-time password. No data collection, no proprietary software. Other areas might be doing bad shit for all I know, but this change is entirely a forced security measure because people are too bad at passwords.

After seing the frequent attempted logins on my Microsoft account, I'm "just" a lucky guess away from losing it if I do not have another thing blocking access.
