How to Turn on Two-Factor Authentication for Twitter

  Twitter logo

Two-factor authentication (2FA) is a great security tool, as it makes it difficult for attackers to enter your account. Most applications make it easy to activate 2FA, and Twitter is no exception. Here's how to enable it.

To begin, you must log in to your Twitter account, either on the Twitter website or on the Twitter application for Android, iPhone or iPad. The process is almost identical for both, except for the starting point.

The 2FA process for Twitter configures SMS messages by default. If you want to use an authentication application, you must perform this process and then switch from using SMS to using an authentication application.

If you are happy to use SMS messaging for your 2FA, you can stop here. Follow the instructions below to change from SMS verification to verification of an authentication application.

Use an authentication application for 2FA

Before making the change, make sure you have downloaded and logged into an authentication application on your smartphone. We recommend Authy, but you will find a good amount of options available in the Google Play Store and Apple App Store.

To use an authentication application, log in to Twitter (if you have not already done so). Then, follow the instructions at the top of the page to access your verification settings (Account> Security> Login verification).

As with the SMS configuration, the process is almost identical if you are using the Twitter website or the mobile application.

In the "Verification methods" section, click on the "Mobile security application" option.
