X Tells Security Key Users to Re-enroll by Nov 10, 2025
🔐 X is asking users who registered passkeys or hardware security keys (for example, YubiKey) as their two-factor authentication method to re-enroll their key by November 10, 2025. The company says current key enrollments are tied to the twitter[.]com domain and must be associated with x[.]com before the legacy domain can be retired. Accounts not re-enrolled will be locked until users re-enroll, choose a different 2FA method, or opt out of 2FA.
