Twitter announced on Wednesday that it will start charging its users for SMS-based two-factor authentication. The move is part of the company’s efforts to increase security and make sure that users are using the strongest form of authentication available.

According to Twitter, only paid subscribers will be able to use texts for two-factor authentication. This means that users who are not paying for the service will have to use other methods of authentication, such as Google Authenticator.

The move has been met with some criticism, as some users feel that it is unfair to charge for a service that was previously free. However, Twitter has argued that the move is necessary in order to protect users from potential security threats.

In response to the announcement, Twitter has also released a guide on how to keep your account secure without giving Elon Musk any money. The guide provides advice on how to use Google Authenticator to enable two-factor authentication.

Overall, the move has been seen as a positive step towards improving security for Twitter users. However, it remains to be seen how users will react to the change and whether or not they will be willing to pay for the service.
