How to

Setup Two-Factor Authentication without a Phone Number

Written by Hassan Abbas

Twitter supported two-factor authentication (2FA). But this service always required you to include a phone number as an additional form of identification. But now Twitter has changed its 2FA system to eliminate that dependency.

While using Twitter, you should be using two-factor authentication. 2FA requires you to enter a password and use a secondary means of proving your identity: something you know your password, with something you have, like a phone, security key, or authentication app.

Recently Twitter included made that a phone number. The problem is that SIM swapping are on the rise, making it possible to hijack phone numbers. In fact, the interesting thing happened to Twitter CEO which may explain the company’s decision to roll out this change for all users.

Twitter’s engineers eliminate the requirement for you to add a phone number to your Twitter account as a secondary means of identification.

Now you can use a mobile security authentication app instead. Google Authenticator, AuthyLastPass and others offer this functionality. These apps generate one-time passwords that stay in lock-step with a server using an algorithm.

according to Twitter security engineer Jared Miller:

If you’re using a physical security key like the Yubikey, unfortunately, you’ll still need to fall back on a mobile security authentication app. He explains that physical security keys are not supported outside of Twitter’s Web interface, and acknowledged it’s an imperfect solution: “We know this might not be ideal but we’re going to keep working on it!”
