X Security Keys Re-Enrollment Deadline - Accounts Locked After Nov 10
X is requiring users who use hardware security keys or passkeys for 2FA to re-enroll by November 10, 2025, as the platform retires the twitter[.]com domain. Failure to re-enroll will lock accounts until users re-enroll, switch 2FA methods, or disable 2FA. Authenticator apps are unaffected.
CORTEX Protocol Intelligence Assessment
Business Impact: Account access interruptions could affect brand and customer operations using X for communications. Technical Context: Security keys were bound to twitter[.]com; re-enrollment binds keys to x[.]com to maintain FIDO assertions.
