Twitter Inc. has announced today that they’ve enabled two-step authentication for users of their social networking service. Like most other services offering two-step authentication, you need to give Twitter a secondary point of contact before you can enable it — in this case, a mobile phone number.

Once enabled, when you access your Twitter account from a new device or from a new location, you will need to enter an authentication code that is sent via text to your phone before you can log in or pair your new app / device.

The process to set up Twitter’s two-step authentication is rather straight forward:

  1. Visit your Twitter account settings page
  2. Select “Require a verification code when I sign in”
  3. Click on the link to “add a phone” and follow the prompts

After you enrol in login verification, you’ll be asked to enter a six-digit code that Twitter sends to your phone via SMS each time you sign in.
