Twitter has finally implemented a two-step authentication feature to keep its users’ accounts more secure. The extra security measure is the use of a phone to verify a user.

“With login verification enabled, your existing applications will continue to work without disruption. If you need to sign in to your Twitter account on other devices or apps, visit your applications page to generate a temporary password to log in and authorize that application,” writes Jim O’Leary, twitter Product Security Team. “Of course, even with this new security option turned on, it’s still important for you to use a strong password and follow the rest of our advice for keeping your account secure.”

“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),” he added. “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. Stay tuned.”Source: Blog.Twitter.com
