Social network X, formerly known as Twitter, is taking another step in its gradual erasure of its original identity. The company has confirmed that the twitter.com domain will be officially shut down by November 10. Users who use hardware security keys or passkeys to log in will have to "re-register" their devices by then, or they will simply lose access to their accounts.
The change was announced by the official X Safety account, which initially offered no explanation. The company only stated that all users using security keys for two-factor authentication (2FA) must re-register. Otherwise, their keys will become inactive after a specified period.

As soon as this information appeared, a wave of speculation about a possible security incident immediately began. However, X quickly issued a statement that this was not a data leak or infrastructure compromise. According to the company, the reason is purely technical - the security keys are currently tied to the twitter.com domain, and in order to continue to function, they must be transferred to a new domain x.com "This change is not related to any security issues. It only affects YubiKeys and passkeys - not other methods like authenticator apps. Re-registering will only update your connection to x.com, as we plan to phase out the twitter.com domain.",” the company said.
Elon Musk's steps confirm that the transition to the X brand is to be complete, including domains and internal systems. But as is often the case with Musk's changes, users are warning that it could be a real mess. Disconnecting the original domain will likely disrupt the functionality of a number of integrated services, from embedded tweets to APIs. Ironically, X is causing problems of its own. Automatic rewriting of links from "twitter.com" to "x.com" in posts has already led to several bizarre situations, when even the company accounts themselves shared broken links or meaningless texts.
