This is definitely good advice. My point here is to note that "phones" are not a good 2nd factor, unfortunately, because they're not that durable and are kind of targets of theft. So moving to solely rely on phone sounds like a bad idea. In my case, this was not the end of the world since I use a Yubikey for Google rather than TOTP, so at least my core email services (which represent a huge identity provider) were fine. (This is also the reason why I could afford to wait to get parts and fix the phone rather than get into some panic mode of having all my digital accounts in a state where I might get locked out at any point.)
