X is transitioning from twitter.com to x.com, affecting users with hardware security keys and Passkeys. They must re-register these credentials by November 10 to maintain access. Other 2FA methods remain unaffected, making this a routine administrative change, not a security response.

Abstract generation in progress

X has announced plans to sunset the twitter.com domain and transition users to x.com as part of its broader brand evolution. This shift extends to security features—specifically, any security keys or Passkeys currently linked to the twitter.com domain will need to be re-registered to x.com within a two-week window. According to reports from PANews citing 9to5Mac, this technical migration is a routine administrative step accompanying the platform’s domain consolidation, not a response to any security vulnerability.

Understanding the Impact on Your Authentication

The change affects users who have configured hardware security keys or Passkeys for account protection. These authentication methods, which are currently bound to twitter.com, will cease functioning unless users complete the rebinding process. X clarified that this transition has no connection to any security incidents and does not impact other two-factor authentication options like the Authenticator app or SMS verification. If you use these alternative 2FA methods, no action is required on your part.

The November 10th Deadline: What Happens Next

Users have until November 10th to migrate their security credentials to the new x.com domain. After this deadline, accounts protected solely by legacy security keys or Passkeys will be locked until users take one of three actions: re-register their security credentials to x.com, switch to a different 2FA method, or disable two-factor authentication entirely. X recommends users who want to maintain their current security setup complete the rebinding immediately to avoid account access issues.

Taking Action: Your Next Steps

To ensure continuous protection and platform access, users should log into their account settings, navigate to security options, and update their Passkeys and hardware security keys to the new x.com domain before the November deadline arrives. This proactive approach ensures a seamless transition during X’s ongoing platform modernization.
