Elon Musk-led social media platform X has announced that it will officially retire the Twitter.com domain on November 10, completing one of the most visible stages in its rebranding process. While the change will have little impact on most users, a small section of the platform’s community could be locked out of their accounts if they fail to update their security settings in time.
The platform’s X Safety account posted a notice warning that users who rely on hardware security keys or passkeys for two-factor authentication (2FA) must re-enrol their credentials under the X.com domain before the November 10 deadline.
The company clarified that this change is “not related to any security concern” and affects only Yubikeys and passkeys. “Security keys enrolled as a 2FA method are currently tied to the Twitter.com domain. Re-enrolling your security key will associate them with X.com, allowing us to retire the Twitter domain,” X stated.
It added that after November 10, any account that hasn’t been updated will be temporarily locked until users either re-register their key, choose another 2FA method, or disable two-factor authentication altogether. However, the company continues to recommend keeping 2FA enabled for better protection against cyber threats.
Those affected need to re-register their credentials under the new domain. To do this, users can open the X.com app or website, go to Settings → Privacy and Security → Account Access → Two-Factor Authentication, and re-enrol their security key or passkey.
If users end up being locked out after the change, they can regain access by re-registering their key, switching to another authentication method, or disabling 2FA — though the latter option is discouraged.
The domain switch is symbolic for Musk. He first launched X.com in 1999 as an online banking start-up, which later merged with Confinity and evolved into PayPal. Musk reacquired the X.com domain from PayPal in 2017, calling it “a name with great sentimental value.”
After buying Twitter in 2023, Musk quickly began turning the social media giant into what he called “X — the everything app,” envisioning it as a one-stop destination for communication, content, and payments.
The decision to retire Twitter.com marks another major step in that direction — a symbolic full circle for Musk’s two-decade-old dream of building an online platform under the X.com banner.
