Twitter accounts at risk: Users must re-authenticate by November 10 as platform moves to X.com

Elon Musk, owner of X (formerly Twitter), announced the final phase of Twitter’s transition to X, marking the end of the platform’s association with the iconic blue bird. This change involves a complete migration of user authentication systems from twitter.com to x.comeffectively retiring the old domain in November.

According to the platform’s official Security account, all users with two-factor authentication (2FA)(including access keys or physical security keys) must re-register their credentials before November 10 to ensure that your authentication methods are correctly linked to the new domain. Users who do not complete this process by the deadline risk temporarily losing access to their accounts until they update their authentication method, select an alternative 2FA option, or disable two-factor authentication entirely.

By November 10, we will ask all accounts that use a security key as a two-factor authentication (2FA) method to re-register their key to continue accessing X. You can re-register your existing security key or enroll a new one.

Authenticator apps will continue to work as usual and no changes are expected for those using them as their primary login method.

However, the interruption of twitter.com domain can cause a variety of interruptions. Old links, embedded content, and automated services that still reference the old domain may stop working or cause errors. Developers and content creators who rely on older integrations may need to update their systems to maintain functionality.

The move is part of Musk’s broader strategy to transform Twitter into X, a platform designed to go beyond social media, integrating messaging, video, payments and other digital services under a single ecosystem. While the rebrand began in 2023, the migration of authentication and core infrastructure to x.com marks one of the last technical steps to complete the transformation.
