Twitter has announced a new security feature which resembles the two-factor authentication offered on websites such as Facebook, Google, and Dropbox. The new feature makes sure that the person logging into your Twitter account is really you, helping you protect your account from phishing and other security breaches.
The new authentication method utilizes your cell phone, making sure you’re really you by sending you a code via text message, which you will have to enter every time you log into Twitter. To activate the secure sign-in, head over to your Twitter Settings page and scroll down to find the new “Require a verification code when I sign in” option. In order to check the option, you’re going to need to add a cell phone number to your Twitter account.
Once your phone number is added and verified, enable the code verification, and you’re done. Unlike other websites that offer a similar feature, Twitter’s two-factor authentication is limited to text messaging, and doesn’t make use of designated apps such as Google Authenticator.
In addition, it seems that Twitter is not yet set up to support this feature worldwide. When I tried enabling it for my account using my local cell phone, I got an error message telling me my carrier was not yet supported, and that I should hold tight and wait until it is. If your carrier is supported, however, this I a feature worth enabling to protect your account from unwanted logins. Just keep in mind that every time you log in to Twitter, you’re going to need your cell phone handy to type in the code.
