Twitter improves security safegaurds

            Twitter improves their security safeguard after some recent attacks.Twitter Inc began introducing new technology  to shore up security for users, responding to a spate of recent attacks on prominent accounts including those owned by the Associated Press and Financial Times.


        Twitter said in a blog post it has begun to introduce "log in verification," a form of two-factor authentication in security industry parlance. The feature asks users to confirm their identity after a typical log-in, by sending a six-digit code to smartphones that must then be typed in to complete a sign-on.

          The micro blogging service, considered one of the most important communications platforms today, has not done enough to help protect users' accounts, critics say. That criticism intensified after a fake tweet sent from the AP's account in April about a non-existent White House explosion briefly roiled U.S. financial markets.

Repeated hacking incidents have raised questions about Twitter's credibility and reliability just as it is beginning to assume a central role in a fast-changing media landscape, with the volume of tweets rising to more than 400 million a day.
