What is Twitter Multi-factor Authentication?
Twitter Multi-Factor Authentication (MFA), also known as 2FA (Two-Factor Authentication), is a security feature that provides an additional layer of protection to your Twitter account.
To enable Multi-Factor Authenticationon your Twitter account, users need to follow the below steps –
Go to your account settings and select “Security and account access”. From there, you can choose to enable MFA through a third-party authentication app or via text message.
While the terms MFA and 2FA are often used interchangeably, it’s worth noting that MFA is a broader term that can encompass more than two factors of authentication, such as biometric data, smart cards, or USB keys.
Why Twitter Discontinued Multi-factor Authentication?
Two-Factor Authentication is now exclusively available for Twitter Blue subscribers only, regular users can no longer secure their Twitter accounts with an extra layer of security.
if you are a Non-Blue member of Twitter and have been using the text messages for 2FA, you must switch to an authenticator app or security key by March 20 or have the 2FA disabled completely on your Twitter account.
