From now on, only paying members of the Twitter Blue service can continue to enjoy SMS two-factor authentication on the platform, an essential feature for keeping your account secure. Fortunately, there's another solution out there – and one that's still free of charge – to help keep your account safe from hackers.
As of March 20, 2023, only Twitter Blue subscribers can use two-factor authentication via SMS to log in to their favorite social network. This type of authentication is a must to help prevent your account getting hacked.
Fortunately, Twitter users still have the option of using a mobile authentication application to receive a verification code to enter each time they log in. This is the easiest alternative, even if it requires installing a separate application, like Google Authenticator or Microsoft Authenticator.
Then, go to the settings of your Twitter account, head to the security section and then to two-factor authentication. To be able to sign in via an authentication application, you'll first be asked to link this service to your Twitter account, simply by scanning a QR code. Once this first code is validated, you will then have to open your authentication application each time you log in to Twitter to get your six-digit validation code. Note that this code is automatically renewed every 30 seconds, for security reasons. In addition to Twitter, this two-factor authentication method also works with most online networks and services.
