In a significant move marking the culmination of its rebranding efforts, X, formerly known as Twitter, has announced the official retirement of the twitter.com domain. Effective November 10, 2025, users who utilize hardware security keys or passkeys for two-factor authentication (2FA) must re-enroll their credentials under the new x.com domain to maintain uninterrupted access to their accounts.
Transition from Twitter.com to X.com
The transition from twitter.com to x.com has been a phased process. Initially, in May 2024, the platform began redirecting twitter.com to x.com, signaling the start of the rebranding initiative. This change was part of a broader strategy to transform the platform into an everything app, encompassing a wide range of services beyond traditional social media functions.

Impact on Two-Factor Authentication
Two-factor authentication (2FA) is a critical security measure that adds an extra layer of protection to user accounts. Among the various 2FA methods, hardware security keys and passkeys are known for their robust security features. These devices are domain-specific, meaning they are tied to the web domain they were initially registered with. As a result, the shift from twitter.com to x.com necessitates re-enrollment of these security devices to ensure they function correctly under the new domain.
Official Announcement and User Guidance
X’s Safety team has communicated this requirement through official channels, emphasizing the need for users to act promptly. The company stated, By November 10, we’re asking all accounts that use a security key as their two-factor authentication (2FA) method to re-enroll their key to continue accessing X. This directive underscores the importance of re-enrollment to prevent potential account lockouts. ([thecondia.com](https://thecondia.com/x-twitter-domain-shutdown-security-keys/?utm_source=openai))
Steps for Re-Enrollment
To facilitate a smooth transition, users are advised to follow these steps:
1. Access Account Settings: Log in to your X account and navigate to the Settings & Privacy section.
2. Navigate to Security Settings: Within the settings menu, select Security and Account Access, then choose Security.
3. Manage Two-Factor Authentication: Click on Two-Factor Authentication to view your current 2FA methods.
4. Re-Enroll Security Key: If you use a hardware security key or passkey, follow the on-screen instructions to remove the existing key associated with twitter.com and re-enroll it under x.com.
It’s crucial to complete this process before the November 10 deadline to ensure continuous access to your account.
Clarification on Other 2FA Methods
X has clarified that this re-enrollment requirement specifically affects users utilizing hardware security keys and passkeys. Other 2FA methods, such as authenticator apps or SMS-based verification, remain unaffected by this domain transition. Users employing these alternative methods do not need to take any action.

Security Implications and Best Practices
The necessity for re-enrollment highlights the security design of hardware keys and passkeys, which are intentionally domain-specific to prevent phishing attacks and unauthorized access. This specificity ensures that even if a malicious actor obtains a security key, it cannot be used on a different domain. Therefore, re-enrolling these devices under x.com is essential to maintain their protective capabilities.
Users are encouraged to take this opportunity to review their overall account security settings. Ensuring that backup 2FA methods are in place can provide additional security and prevent potential access issues in the future.
Broader Context of the Rebranding Effort
The retirement of the twitter.com domain is a significant milestone in X’s rebranding journey. Since Elon Musk’s acquisition of Twitter in 2022, the platform has undergone substantial changes, including the adoption of the X branding and the vision to evolve into a comprehensive service platform. The transition to x.com aligns with this vision, aiming to offer users a unified and expanded experience.

Conclusion
As X finalizes its transition from twitter.com to x.com, users employing hardware security keys or passkeys for two-factor authentication must re-enroll their devices under the new domain by November 10, 2025. This proactive step is crucial to ensure uninterrupted access and maintain the security integrity of user accounts. By adhering to the provided guidelines and completing the re-enrollment process promptly, users can seamlessly adapt to this change and continue to enjoy the services offered by X.
