Elon Musk’s Twitter started a security ruckus over the weekend with the sudden decision to turn off text message/SMS method of two-factor authentication (2FA) for anyone not subscribed to its paid Twitter Blue service.
“While historically a popular form of 2FA, unfortunately we have seen phone-number based 2FA be used – and abused – by bad actors. So starting today, we will no longer allow accounts to enroll in the text message/SMS method of 2FA unless they are Twitter Blue subscribers,” Twitter announced late Friday.
