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

▤ Summary

X requires anyone using a security key for two-factor authentication to re-enroll that key by November 10. The change comes from the retirement of the twitter.com domain, which means keys tied to the old domain will stop working. Users can re-enroll through the X website or app, switch to an authenticator app, or choose another 2FA method. X says the update affects security keys and passkeys tied to twitter.com, not other authentication methods. The notice creates a near-term action for users who rely on hardware security keys to keep account access uninterrupted.
