Starting from March 20, 2023, two-factor authorization (2FA) via SMS on Twitter will be available exclusively to those users who have purchased a paid Twitter Blue subscription . For gadgets on Android, it costs $8 per month, and for iOS devices – $11 per month. It is reported by The Verge.

Other 2FA methods, including using a physical security key, will continue to be free.

Twitter explains the innovation by the fact that 2FA by SMS is allegedly not a very reliable way to verify your identity. The social network refers to an incident where the account of the then head of the social network, Jack Dorsey, was hacked four years ago. The hackers then cloned Dorsey’s SIM card and were able to bypass 2FA via SMS in this way.

But The Verge believes that Twitter is actually giving up 2FA for SMS because the IT company has to pay by SMS. Twitter, which is currently going through a financially difficult period, is trying to save money in this way, according to the publication.

To recap, billionaire Elon Musk said that the social network Twitter will share its own profits from advertising with users of the resource. This enticing promise was made by the head of Twitter to users on his page on the social network.
