Together with a new updated Mac app with built-in Notification Center integration, released by Twitter, it also announced a system-wide two-factor authentication solution for heightened account security. Two-factor authentication uses your password and an additional method to verify your identity.
Such a login verification feature can be selected to require entry of a six-digit code, in addition to their standard password, to gain access to their Twitter accounts. To receive it, people have go to account settings and select “Require a verification code when I sign in.”
Then the user has to confirm his e-mail and verify the phone number. Thus, when signing into Twitter on a new device or new app, he’ll receive an SMS with a six-digit code. After using it to enter the system new device can be fully used to communicate. Users will receive a six-digit code each time they sign in to Twitter.
“With login verification enabled, your existing applications will continue to work without disruption,” Twitter said. “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.”
With the two-factor authentication, most hacks are expected not to work as they wouldn’t have access to password for the account. The additional security measure complicates the login process, but Twitter believes it’ll be welcomed by most its users. The Associated Press’ account was cracked, when hackers sent out a message claiming the White House had been bombed.
