Social media platform X announced that its security keys and Passkeys are currently bound to "twitter.com." To "retire" the domain, it requires accounts using hardware security keys or Passkeys to re-register to "x.com" within two weeks. Otherwise, the keys will become invalid and the accounts will be locked. X emphasized that this move is not related to the security incident and does not affect other 2FA methods such as the Authenticator app. An official statement stated that those who have not re-bound their accounts after November 10th will need to re-register, switch to a different 2FA method, or disable 2FA to unlock their accounts.
