RIP Twitter. 

X, the platform formerly known as Twitter, will retire its old domain. This comes with a warning for you: If you don’t update your account’s security settings soon, you could be locked out. 

The shift marks another step in Elon Musk’s ongoing rebrand of the social network over the last two years. Musk, who bought Twitter in October 2022 and later renamed it X, has made sweeping changes to the platform’s features and policies.

The company notified users that anyone using hardware security keys or passkeys tied to twitter.com must reenroll them under the new x.com domain. The deadline is Nov. 10. After that date, affected accounts may be temporarily locked until the update is completed.

X emphasized that the move isn’t related to a data breach or security issue but is a necessary step in the platform’s domain transition, marking the end of Twitter’s last remnants.

«This change is not related to any security concern, and only impacts Yubikeys and passkeys, not other 2FA methods (such as authenticator apps),» the company’s Safety account stated on X. Because security keys enrolled as a two-factor authentication method are currently tied to the former domain, reenrolling your security key will associate them with the new domain. 

For most users, the change will go unnoticed. But if you rely on physical security keys, such as YubiKeys, or use passkeys for password-less login, you could be caught off guard if you don’t take action before the cutoff date.

How to reenroll your X account

1. Check your login method. If you use a hardware security key or passkey, it’s likely tied to twitter.com.
2. Reenroll your key or passkey. Go to Settings & privacy > Security and Account access > Two-factor authentication and add your method under x.com.
3. Update your saved credentials. Make sure your logins now point to x.com instead of twitter.com.
