I think those things are incompatible, or at least Twitter really gives that impression. Great recommendation /s
While no passwords were exposed, we encourage everyone who uses Twitter to enable 2-factor authentication using authentication apps or hardware security keys to protect your account from unauthorized logins.
So it actually does not imply adding a phone number, which is seemingly what you have tried to imply with the cut-off quote provided.
It actually does.
The sentence you quoted contains the link "enable 2-factor authentication", which goes to a page where adding a phone number is the FIRST method described.
"There are three methods to choose from: Text message, Authentication app, or Security key..... If you don’t already have a phone number associated with your account, we’ll prompt you to enter it."
