Twitter has announced that only Twitter Blue subscribers will be able to use two-factor authentication via SMS. The restriction will be introduced on March 20.
Users who do not wish to sign up for a subscription can enable two-factor authentication (2FA) through the Google Authenticator app. 2FA is optional, but is generally recommended by Twitter, as it’s more difficult to hack into an account.
Now, according to an official statement from the social network, Twitter is limiting two-factor authentication because it is less secure. As Variety noted, it’s unclear why this method of protection is still available to subscribers.
Earlier, Twitter announced an innovation: it increased the limit on the number of characters in posts on the social network. Now, instead of the standard 280, there are 4,000 available to users, but this only applies to owners of blue marks.
