I still have an account so I can see replies and such. Elon made SMS codes part of Twitter Blue, but authentication apps and security keys are free. It might be one of the only somewhat sensible things he’s done with the site, seeing as it’s pretty expensive to send out codes over SMS.
Authentication code apps are free.
