X.com Domain Change: Prevent Account Lockout by November 10th
X (formerly Twitter) is changing its website domain from Twitter.com to X.com.
If you use a special key or code to protect your account (like a security key or passkey), you need to update it.
If you don't update it before November 10th, you might not be able to log into your account.
To update, go to your security settings on X.com and re-register your key or passkey.
This change is not due to any security problems, but because of the domain switch.
If you do get locked out, you can get back in by re-registering your security key, choosing a different way to protect your account, or turning off the extra security.
X is retiring the Twitter.com domain.
Users relying on hardware security keys or passkeys for two-factor authentication must re-register on X.com.
Failure to re-enroll before November 10th may result in account lockout.
The change is related to the domain transition, not security concerns.
Users can regain access by re-enrolling, selecting a different 2FA method, or disabling 2FA.
