Twitter Adds Two-Factor Authentication, How To Enable It Now

Twitter has finally added two-factor authentication and you should enable it right now if you can. We probably don’t need to tell you why, but just in case you forgot about social engineering hacks, you want to enable this feature to protect yourself.

To enable two-factor authentication in Twitter, you first need to verify your phone number and email address. (The only officially supported carrier that works with Twitter in Australia appears to be Telstra; if you do get this working with Optus or Vodafone, let us know in the comments.) With that complete, follow these steps:

  • Visit your account settings page.
  • Select “Require a verification code when I sign in.”
  • Click on the link to “add a phone” and follow the prompts.
  • You’ll be asked to enter a six-digit code sent to your phone via SMS each time you sign in to (Note: That doesn’t mean every time you access Twitter, but just when it requires you to sign in.)

For more information, check out the full post on Twitter’s blog.

  • “This release is built on top of Twitter via SMS, so we need to be able to send a text to your phone before you can enroll in login verification (which may not work with some cell phone providers). ”
    Doesn’t work with Optus.
