X announced the end of the twitter.com domain; necessary actions must be taken by November 10
Company X has announced that users who use two-factor authentication (2FA) must re-register their hardware security keys and passwords by November 10. Users who refuse to comply with this requirement risk having their accounts blocked. This change is related to the reissuance of authentication keys in the new system, as the existing keys are linked to the twitter.com domain.

It is worth noting that the change is not related to security issues. It only affects Yubikey keys and passwords, not other 2FA methods such as mobile authenticators. Removing support for the twitter.com domain could cause numerous problems for users, as automatically replacing links to the new x.com domain could cause issues even in company accounts. In this regard, the company's specialists plan to conduct testing over the next two weeks to avoid possible disruptions.
