Four hours ago, Platformer’s Zoe Schiffer tweeted a scoop: Twitter would begin charging for SMS two-factor authentication.
Now, it’s official: You have to pay for the privilege of using Twitter’s worst form of authentication. In fact, if you don’t start paying for Twitter Blue ($8 a month on Android; $11 a month on iOS) or switch your account to use a far more reliable authenticator app or physical security key, Twitter will simply turn off your 2FA after March 20th.
I know which one I would choose.
That’s how Twitter is trying to justify this change, too, but I wouldn’t be surprised if there’s a simpler reason: it costs money to send SMS messages, and Twitter does not have a lot of money right now. The company had been phasing out SMS even before Elon Musk took over.
