Update your Twitter two-factor authentication

What’s happening?

Effective 20 March 2023, we will no longer support two-factor authentication using text messages for non-Twitter Blue subscribers, in favor of authentication apps and security key methods. At that time, if you have text message 2FA still enabled, you will be prompted to disable it before you can continue to use your account. Please note the availability of text message 2FA for Twitter Blue may vary by country and carrier.

What will happen to accounts that don’t switch 2FA methods before March 20?

After 20 March 2023, we will be doing two things:

(1) For users who have seen Twitter’s in-app prompt to change their text message/SMS method of 2FA (pictured), we will disable the text message 2FA method automatically. These users will continue to be able to login; they just won’t have 2FA on their account unless they have switched to using an authentication app or security key.

We are prompting users to consider enabling an alternative form of 2FA before that happens. It’s not mandatory to use 2FA for the majority of accounts, so we are not forcing this. However, most businesses require 2FA as a standard practice.

(2) Users and businesses who have not seen the prompt will be required to actively unenroll themselves from the text message 2FA method. These accounts will still be able to log-in, but they will be immediately prompted to complete the task. This will ensure users and businesses who haven't seen the in-app prompt do not have 2FA disabled without their awareness.

How do I sign-up for two-factor authentication on Twitter?

1) App Authentication (secure): follow this step-by-step guide.

2) Security Key (safest): see our guidance on security keys and an example of how we rolled them out at Twitter.
