X marks the lock

X marks the lock: If you use a physical security key (like a YubiKey) for 2FA on X, you’ve got until Nov. 10 to reenroll, or your account gets locked. Why? X is cutting ties with the old Twitter.com domain, which means you’re basically reregistering your key under X.com. Authenticator and SMS 2FA folks? No action needed.
