Two-factor authorization (2FA) is considered a more secure way to sign into an app or website. It requires that two layers of information be presented. Typically, after punching in a username and password the user receives a code on his phone via Text/SMS that he enters into the app or site to gain entry. Considering that most people carry their phones with them wherever they go, this is probably one of the easiest ways to implement 2FA although it might not be the most secure.
If you want to keep SMS 2FA on Twitter after March 20th, you’ll need to subscribe to Twitter Blue
Twitter adds that “We encourage non-Twitter Blue subscribers to consider using an authentication app or security key method instead. These methods require you to have physical possession of the authentication method and are a great way to ensure your account is secure.”
Subscribing to Twitter Blue will cost you $8 per month ($84 for a year) and besides getting to use Text/SMS 2FA, you can enjoy features like Edit Tweet. The latter gives you a 30-minute window to make limited changes to a tweet that you’ve posted. Another feature available to subscribers is an increase in the maximum number of characters allowed in a tweet from 280 to 4,000. Another feature will give prioritization to replies that you send to tweets that you’ve interacted with.
Other perks for Blue members include the Reader feature that makes long tweets look better, and one that allows members to upload longer video content of up to 60 minutes in length (no more than 2GB in size). And with Top Articles, you get to see the most shared articles from Twitter users you follow.
