How to use two-factor authentication to log in to Twitter, with no SMS code

TWITTER recently announced the end of free two-factor authentication, which works by sending users a secret, temporary code via SMS. Fortunately, there's another free solution available to help protect your Twitter account from hackers.

As of March 20, 2023, only Twitter Blue subscribers will be able to 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 connect 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.
