After a series of nasty hacks of high-profile accounts, Twitter just
turned on a feature that’s becoming the new normal in Web application
security: two-factor authentication.
As the video above shows, Twitter users can now sign up to have a unique code sent to their phone by text message whenever they log in from a new computer. That ensures that any hacker who tries to steal your password, say with a phishing attack or keylogging spyware, would also have to compromise your phone, too, creating a serious security barrier.
