How to Set Up App-Based Two Factor Authentication on Twitter for Free. Twitter has announced that it will soon stop supporting SMS based two-factor authentication (2FA) for users that are not subscribed to Twitter Blue. Users will have up to March 20 to disable text-based login authentication codes on their accounts, according to the microblogging service. This means that several users who rely on receiving SMS codes to protect their account will have to subscribe to Twitter Blue. For those who do not want to subscribe, Twitter will continue to support alternative 2FA methods at no extra cost.
