Rebinding Security Keys to X by November 10 Required

X Holdings Corp., led by Elon Musk, announced users must re-register security keys for ‘x.com’ by November 10, 2025, after retiring the ‘twitter.com’ domain.

This update, unrelated to security issues, impacts Yubikey and Passkey users, prompting potential disruptions in two-factor authentication processes.

Significant User Action as X Mandates Security Key Updates

X Holdings Corp., under Elon Musk’s ownership, has signaled a significant security update. The rebranding from “twitter.com” to “x.com” by November 10, 2025, mandates users to re-register hardware security keys tied to their accounts. The X Safety team released their official notice emphasizing how the change is unrelated to prior security incidents.

“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… To clarify: this change is not related to any security concern, and only impacts Yubikeys and passkeys—not other 2FA methods (such as authenticator apps). 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 Safety, Official X Account, source

Community and developer reactions have surfaced concerns over this domain shift. Key figures have not directly commented on potential systemic impacts. However, users have reported glitches linked to auto-replacements of domain text, which suggest minor technical errors stemming from the migration process.
