Elon Musk’s X botched its security key switchover, locking users out

Reports indicate that X’s mandatory migration of passkey and hardware security key 2FA from twitter.com to x.com has left many users locked out or stuck in re-enrollment loops after a November 10 deadline, while authenticator app users are unaffected. Because passkeys/security keys are bound to the original domain, users must manually re-enroll on x.com, but many are encountering errors. X has not commented on the disruption.
