Do you log into X with a security key? Re-enroll it by Nov. 10 - or else

"In an X post from Friday, the network's Safety account said that anyone using a security key as their two-factor authentication (2FA) method must re-enroll that key by November 10. If you miss that deadline, your existing security keys will stop working, and you'll be locked out of your account. At that point, you can still re-enroll, select a different 2FA method, or opt not to use 2FA."

"To re-enroll, fire up the X website or mobile app. Select the More button, click the option for Settings and privacy, go to Security and account access, select the option for Security, and then click "Two-factor authentication." Select the option for Security key. Make sure the security key is plugged into your computer or mobile device, and then follow the steps to enroll the key."

"If you no longer want to use the security key, you can choose the "Authenticator app" option instead. For this, you can use an app like Microsoft Authenticator or Google Authenticator to generate codes to use each time you need to sign in to X on a different device. Just don't pick the option for SMS text messages, as that's the least secure type of 2FA and one vulnerable to hacking."

Any X account using a physical security key for two-factor authentication must re-enroll the key by November 10. Failure to re-enroll will cause existing security keys to stop working and lock users out of their accounts. Users can re-enroll through the X website or mobile app via Settings and privacy → Security and account access → Security → Two-factor authentication, selecting Security key and following the enrollment steps. Users can instead choose an authenticator app like Microsoft or Google Authenticator. SMS-based 2FA is discouraged because it is the least secure and vulnerable to hacking.
