Four hours ago, platformsby Zoe Schiffer tweeted a scoop: Twitter would start 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/mo on Android; $11/mo on iOS) or switch your account to use a much more reliable authenticator app or physical security key, Twitter will simply turn off your 2FA after March 20.
I know which one I would choose.
This is how Twitter is trying to justify this change as well, but I wouldn’t be surprised if there’s a simpler reason: it costs money to send SMS messages, and Twitter doesn’t have a lot of money right now. The company had been removing SMS even before Elon Musk took over.
