Twitter has introduced two-factor authentication to better protect your Twitter account.

The feature well known at Google is henceforth available for Twitter members. This means when you sign in to twitter.com, there’s now a second check to make sure it’s really you. Twitter
will ask to register a verified phone number and a confirmed email address. 

To implement the feature, follow these steps:

1.     Visit your account settings page.

2.     Select “Require a verification code when I sign in.”

3.     Click on the link to “add a phone” and follow the prompts.

4.     After you enroll in login verification, you’ll be asked to enter a six-digit code that Twitter sends to your phone via SMS each time you sign in to twitter.com.

‘’This release is built on top of Twitter via SMS, so we need to be able to send a text to your phone before you can enroll in login verification (which may not work with some cell phone providers). However, much of the server-side engineering work required to ship this feature has cleared the way for us to deliver more account security enhancements in the future.’’  Has said, Jim O’Leary (@jimio), Product Security Team.
