Social media platform X, formerly known as Twitter, is experiencing widespread technical disruptions as it transitions its security infrastructure, leaving millions of users who rely on hardware security keys and passkeys unable to access their accounts.

The company announced on October 24 that, as part of its migration from twitter.com to x.com, users with physical security keys and passkeys must manually re-register their credentials under the new domain. Accounts that use authentication apps are not affected by the change.

X explained that security keys and passkeys are digitally tied to the domain where they were originally registered, preventing an automatic transfer to x.com. While the move aims to enhance security and finalize the platform’s domain transition, it has inadvertently created significant user friction.

Despite warnings that accounts not re-registered by November 10 would be locked, many users reported persistent errors, infinite login loops, and in some cases, complete inaccessibility. Online forums and social media channels have seen a surge of complaints from frustrated users struggling to regain access.

The disruption adds to a series of challenges for the platform since Elon Musk’s acquisition, including large-scale layoffs, system inconsistencies, and ongoing public controversies. X management has not released an official statement on the current issues, although Musk himself continues normal activity on his account.

Security experts say the problems underscore the complexity of digital authentication systems, particularly during transitions of core infrastructure such as domain-linked security keys. Users are strongly advised to follow X’s updated instructions to complete the re-registration process and avoid prolonged account lockouts.

X is reportedly working to resolve the technical issues while urging affected users to carefully follow guidance available on the platform to regain full access. (ILKHA)
