X, the platform we all still accidentally call Twitter sometimes, just announced something pretty major. They’re officially saying goodbye to the twitter.com domain for good. And if you use certain security features to protect your account, you need to take action before November 10, or you might find yourself locked out. Let me break down what’s happening and what you need to do.
What’s Changing
X is asking all users who use hardware security keys as their two-factor authentication method to re-enroll their credentials by November 10, 2025, or they’ll be locked out of their accounts. This isn’t just a suggestion. It’s a requirement.
Why the sudden urgency? Well, the security keys currently in use are tied to the old twitter.com domain, and since X is moving everything to x.com, users need to re-register their security keys with the new domain. It’s kind of like updating your address when you move to a new house. Your keys need to know where home is now.
The good news is this change is not because of any security incident but merely a technical requirement from the domain change. So nobody’s been hacked, and your data isn’t at risk. This is just part of X’s complete transition away from its Twitter identity.
Who Needs to Worry About This
Before you panic, let me clarify something important. This change only impacts those using security keys or YubiKeys, and does not impact people using other two-factor authentication methods.
So if you’re using your phone to get text codes or an authenticator app to log in, you’re totally fine. You don’t need to do anything. Go ahead and grab that coffee you’ve been thinking about.
But if you do use a physical security key, like a YubiKey, or if you use passkeys for password-less login, then yes, you absolutely need to take action. Some users may have switched to security key access back in 2023 when X removed SMS authentication as a free option, so you might be using this method without even realizing it.
How to Update Your Security Settings
Okay, so you’ve determined you need to update your security key. What now? Don’t worry, it’s actually pretty straightforward.
Go to Settings and privacy, then Security and Account access, then Two-factor authentication, and add your security key method under x.com. That’s it. You can either re-enroll your existing security key or set up a new one. The platform will walk you through the process.
X says they’ll automatically prompt affected users when they log in, so hopefully you’ll get a clear notification. But honestly, I wouldn’t wait around for that. It’s better to be proactive and check your settings yourself rather than risk getting locked out right when you need to access your account.
What Happens If You Don’t Update in Time
Let’s say you miss the November 10 deadline. What then? After November 10, if you haven’t re-enrolled a security key, your account will be locked until you re-enroll, choose a different two-factor authentication method, or elect not to use 2FA.
Basically, you won’t lose your account permanently, but you will be locked out temporarily. You’ll need to go through the re-enrollment process to get back in, or you’ll have to switch to a different security method entirely. X still recommends keeping some form of two-factor authentication active to protect your account, which honestly is good advice for any online platform.
