X Social Network Now Requires Security Key Re-Enrollment

The social media platform X is now requiring users to re-register their security keys. This new measure affects those who rely on physical authentication devices for account protection, prompting them to update their credentials to maintain secure access.

X.com Transition: A New Era for Account Security

With the looming deadline of November 10, 2025, all users of X—formerly known as Twitter—who rely on hardware security keys or passkeys are facing an urgent task. The root cause is not a security flaw, but rather the definitive transition from the legacy domain twitter.com to the streamlined address x.com, a rebranding orchestrated by Elon Musk. While the name change has been on the horizon for some time, this technical migration carries significant consequences for account access.

The Authentication Reset: A Technical Hurdle

As a direct result of this domain change, any method of two-factor authentication previously registered under the old domain will cease to function after the switchover. This affects physical devices like Yubikeys as well as passkeys saved on computers or smartphones. If no action is taken, users risk being locked out until they complete a new registration process or switch to an alternative verification method.

Several factors explain this decision:

• Re-registering security keys or passkeys via account settings is essential.
• Selecting a different two-factor authentication (2FA) method remains an option.
• Total deactivation of double authentication is strongly discouraged by cybersecurity specialists.

The Case for Stronger Protection

Why such emphasis on keeping two-factor authentication active? According to analysts cited in outlets like Bleeping Computer and Tom’s Guide, both hardware-based and digital passkeys provide far greater defense against phishing campaigns and hacking attempts than traditional passwords. Because these technologies use local cryptographic verification—typically tied to a dedicated device—they are much less susceptible to malware or online scams.

Navigating the Update Process

Although some users may find this transition cumbersome, updating security settings involves a straightforward sequence: log into your account through x.com, deactivate any outdated key or passkey, then enroll a new one. A final step—entering your password to verify your identity—completes the process. While it might be tempting to postpone this task, procrastination could lead to being unexpectedly locked out of what is now Elon Musk’s flagship social platform. Anticipating and adapting to these changes remains the surest way to safeguard your digital identity in this evolving landscape.
