Twitter has stated that it would shortly stop offering SMS-based two-factor authentication (2FA) for users who do not have a Twitter Blue subscription. According to the microblogging site, users will have until March 20 to disable text-based login authentication codes on their accounts. This implies that many users who rely on SMS codes to safeguard their accounts will have to sign up for Twitter Blue. Twitter will continue to enable alternate 2FA options at no additional cost for anyone who does not wish to subscribe.
While Twitter has stated that the rationale for discontinuing free access to SMS-based 2FA was due to "bad actors" abusing the phone-number system, the microblogging service's post also states that access to SMS-based 2FA for Twitter is still available. Twitter Blue subscribers "may vary by country and carrier."
