X Sets Nov. 10 Deadline to Re-Enroll Security Keys as Twitter.com Is Retired

X says the move aligns security credentials with x.com rather than responding to a breach.

X is finally saying goodbye to Twitter.com, and users must act fast to keep access.

Overview

  • Users who rely on YubiKeys or passkeys must re-enroll them via Settings > Security > Two-factor authentication to keep access.
  • Accounts not updated by November 10 will be locked until users re-enroll, choose another 2FA method, or disable 2FA.
  • Authenticator apps and SMS-based codes are not affected by the change.
  • X explains that keys registered to twitter.com will not work on x.com because security credentials are bound to the domain used at enrollment.
  • Retiring twitter.com may also disrupt links, embeds, and third‑party integrations that still reference the old domain.
