Today, Twitter has rolled out an update that allows users to add a phone number to the account. The idea is simple. Every time a users signs-in there is added code that is asked. That code is sent to users via a text message.
So even if someone manages to guess a password, they would not be able to get the verification code from the users phone.
How to activate Twitter’s two-step authentication feature
- Visit your Twitter profile on the browser and sign-in. Now on the right-hand corner you will see a gear shaped symbol.
- Hover over it and it shows you the options to look up settings. Under Settings >> Account users can see a new option to titled Account Security.
- We can add a phone number and also select the option to turn-on two step verification.
