Recently, it was announced that Twitter would only offer SMS-based two-factor authentication (2FA) to its Twitter Blue members (those who are willing to pay $8 a month on Android or $11 a month on iOS). To tell you the truth, my first reaction was: just as well. If you want to use 2FA to secure your social media or another account, using text messaging is not the way to go. You’re much better off using either a third-party authenticator app or a hardware security key.
