Important Update on 2FA Authentication for X
X is retiring the Twitter domain for 2FA authentication to ensure domain trust, according to Christopher Stanley, a security engineer at X, xAI, and SpaceX.
Users who have enabled two-factor authentication using a hardware key like YubiKey must re-enroll their keys before November 10 to avoid being locked out.
By November 10, we’re asking all accounts that use a security key as their two-factor authentication (2FA) method to re-enroll their key to continue accessing X.
This change only affects hardware key 2FA authenticators and does not impact other 2FA authenticators like Google Authenticator, Microsoft Authenticator, or Authy.
