X, the social media platform formerly known as Twitter, quietly announced that the twitter.com domain would be shutting down and that the company would require anyone using a security key (YubiKey or password) to perform two-factor authentication (2FA).
Last week security account X published that all accounts that use a security key as a 2FA method must re-register their security key by November 10 to continue using X. The company also noted that you can re-register using the same security key or create a new one.
After November 10 if any users have not re-registered their securitytheir accounts will be locked until they re-register, switch to a different 2FA method, or decide not to use 2FA at all.
Of course this led to speculation that the company's authorization infrastructure was compromised. However, security account X posted a message explaining that the security keys were currently registered to the old domain. The new security keys will be tied to the x.com domain, allowing the brand to move away from twitter.com.
Users also noted that a lot would break if X decided to ditch the domain name entirely, with some noting that much of the social media platform's back end still uses the old Twitter.com domain. 9To5Mac noted that automatically replacing X twitter.com with x.com in tweets resulted in accounts from companies such as Grok AI posting tweets that may initially seem nonsensical.
To add some context, Twitter has (slowly) switched to X branding. last May, completion owner Elon Musk a vision of shaking up a long-standing platform.
