Social media platform X has issued a directive to users who utilize two-factor authentication (2FA) through passkeys and hardware security keys, such as Yubikeys, to re-enroll their devices by November 10, 2025. This measure is essential to ensure uninterrupted access to their accounts.
The re-enrollment process can be completed using the existing security key or by registering a new one. Failure to comply by the specified date will result in account lockouts. In such cases, users will need to re-enroll their security key, select an alternative 2FA method, or opt out of 2FA altogether. However, X strongly recommends maintaining 2FA to enhance account security.
This initiative is part of X’s broader strategy to phase out the twitter[.]com domain. Following its acquisition by Elon Musk in October 2022, Twitter underwent a rebranding to X in July 2023. The company has clarified that this change does not affect users who employ other 2FA methods, such as authenticator apps.
The necessity for re-enrollment arises because security keys are currently linked to the twitter[.]com domain. By re-enrolling, users will associate their security keys with the x[.]com domain, facilitating the retirement of the Twitter domain.
X also offers 2FA via text messages, but this option has been restricted to non-Premium subscribers since March 20, 2023.
To re-enroll a security key, users should follow these steps:
1. Navigate to Settings and privacy > Security and account access > Security > Two-factor authentication.
2. Select Security key > Manage security keys > Delete existing keys.
3. Choose the Security key option > Enter X password > Enter confirmation code sent via email.
4. Click Start > Insert key into the computer’s USB port or connect via Bluetooth/NFC > Once inserted, touch the button on the key.
5. Follow the on-screen instructions to complete the setup.
By adhering to these guidelines, users can ensure continued access to their X accounts and maintain robust security measures.
