Twitter has announced that it will soon stop supporting SMS-based two-factor authentication (2FA) for users who are not subscribed to Twitter Blue. Users have until March 20 to disable text-based authentication codes for 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 don’t want to subscribe, Twitter will continue to support alternative 2FA methods at no additional cost.
While Twitter has explained that the reason for shutting down free access to SMS-based 2FA was because the phone number mechanism was being abused by “bad actors,” the microblogging service’s post also says that access to SMS-based 2FA for Twitter Blue subscribers “may vary by country and carrier.”
If you don’t want to pay Twitter a hefty monthly fee, Twitter Blue costs up to Rs. 900 per month in India – for SMS based two-factor authentication to protect your account, you can switch to a more secure option to protect your account through authentication apps.
