As documented here, wordpress cookies name have HASH part. I wonder to know what is its use-case?

  • It's there in the docs you linked: "It’s quite hard to reverse a hash (bordering on practical infeasibility with today’s computers). [...] WordPress uses the two cookies to bypass the password entry portion of wp-login.php."
