Twitter adds security step through text code

5/23/2013

NEW YORK — Twitter is adding an extra security measure to users’ accounts in an effort to prevent unauthorized logins.

Twitter said in a blog post Wednesday that users will be able to enroll in a login verification program. For those who sign up, Twitter will send a six-digit code using a text message each time they sign in to Twitter.com. Besides their user name and password, users will have to enter the code as well to log in.

Microsoft Corp., Google Inc., and Facebook Inc. already allow two-step verification as an option. Twitter has been criticized for not having this option, especially following recent breaches of Twitter accounts belonging to major news organizations and other companies.
