Two-factor authentication (2FA) via text message for Twitter non-subscribers will be discontinued.
Users can add an additional layer of security to their online accounts beyond passwords by using 2FA, which double-checks the identity of the individual logging in.
Texting consumers a code or utilising an authenticator app are two popular techniques.
Only Twitter Blue subscribers will be allowed to use text-message authentication starting on March 20, according to a tweet from the Twitter Help account on Saturday.
Several texts Users of 2FA also got a notification in-app advising them to stop using the method before the deadline to save their account access.
Elon Musk, the CEO and owner of Twitter, announced that the authenticator app was more secure and will continue to be offered without charge.
He claimed to a critic of the decision that Twitter had been “scammed” by phone providers and was spending more than $60 million (£49 million) year on “false 2FA SMS messages.”
“We encourage non-Twitter Blue subscribers to consider using an authentication app or security-key method instead,” it said.
“These methods require you to have physical possession of the authentication method and are a great way to ensure your account is secure.”
