1. Users of Elon Musk's X social media platform are experiencing issues with a mandatory two-factor security change that has resulted in endless loops and account lockouts, affecting those who use passkeys or hardware security keys as their method of authentication.

2. On October 24, X asked users relying on these methods to re-enroll using the x.com domain due to a retirement of the older twitter.com domain. However, the problem lies in that passkeys and security keys are tied to the old domain and can't be transferred to x.com, requiring manual un-enrollment and re-enrollment.

3. This issue is the latest controversy for X, which was purchased by Elon Musk and has since experienced mass layoffs and numerous controversies under his ownership. Despite these issues, Musk himself appears unaffected and continues to post as usual on the platform.
