X Users Locked Out Due to Security Key Migration Issues

Users of X, formerly known as Twitter, are facing significant login issues following a mandatory two-factor authentication (2FA) change implemented on October 24, 2025. The platform, now owned by Elon Musk, required users relying on passkeys or hardware security keys, such as YubiKeys, to re-enroll using the new x.com domain. This change is part of X's effort to retire the older twitter.com domain, which began redirecting to x.com in May 2024. However, the migration has resulted in numerous users being locked out of their accounts, unable to complete the re-enrollment process.

The core issue stems from the fact that passkeys and security keys are cryptographically tied to the twitter.com domain, preventing a straightforward transfer to x.com. Users must manually un-enroll from the old domain and re-enroll with the new one. Many have reported being caught in endless verification loops or receiving error messages that prevent them from accessing their accounts. As of November 10, the deadline for re-enrollment, numerous users reported being locked out entirely, with some expressing frustration over the inability to log in despite following the required steps.

While X has not officially acknowledged the widespread issues, reports indicate that the company's engineers are working to revert the recent changes in an effort to restore service. Users have shared their experiences on social media, highlighting the confusion and frustration caused by the migration process. One user noted, "I got stuck in the same infinite loop - completely locked out now," while another mentioned, "I actually managed to re-enroll my YubiKey on my mobile through NFC, and it just keeps looping through 'you must re-enroll' even though I've done the re-enrollment."

Critics have pointed out that the migration process disproportionately affects users who prioritize security, as those relying on hardware keys are now facing access issues. The irony of a security migration causing significant lockouts has not gone unnoticed, with many users expressing dissatisfaction with X's handling of the transition. The situation has raised concerns about the platform's technical stability and its ability to manage user security effectively.

While many users are experiencing significant issues, some reports suggest that a majority of users remain unaffected and can still access the platform without problems. This discrepancy raises questions about the scale of the outage and the effectiveness of X's communication regarding the changes. Additionally, the lack of an official response from X regarding the ongoing issues leaves a gap in understanding the company's plans to resolve the situation.

As X's engineers work to address the login issues, users are advised to monitor updates from the company and follow the re-enrollment process as outlined. The situation remains fluid, and further developments are expected as the platform navigates the fallout from this security key migration.
