How about actually displaying this message to users, instead of just posting it on your feed? You displayed a vague message asking if we want to improve our security. Now many accounts are locked out today, seemingly due to some bug setting up Yubikeys.

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. You can re-enroll your existing security key, or enroll a new one.
A reminder: if you enroll a new security key, any other security keys will stop working (unless also re-enrolled).
