If you’re a former Twitter user still using and rely on a hardware security key for your two-factor authentication (2FA) method, you need to re-enroll it before November 10. As spotted by , X’s account notified users of the deadline in a post last week. The Elon Musk-owned company eventually intends to retire the twitter.com domain, which hardware keys such as YubiKeys remain tied to until they’re re-enrolled.
“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. You can re-enroll your existing security key, or enroll a new one. A reminder: if you enroll a new security key, any other security keys will stop working (unless also re-enrolled),” the account said.
X later clarified that the change only applies to YubiKeys and passkeys, and not 2FA authenticator apps such as Microsoft Authenticator or Authy. Users who fail to re-enroll their affected keys before November 10 will have their accounts locked until they either complete the re-enrollment process, choose a different 2FA method or decide to not use 2FA altogether (which X says it advises against).
To re-enroll your hardware key or add a new one, head to Settings in the X app, then click “Security and account access” and “Manage Passkeys” within the Security section.
Elon Musk Twitter to X in 2023, and last year fully the social network’s core systems to X.com, leaving no trace of the blue bird logo that was once synonymous with the platform.
