If you are a shared hosting plan and add the domain name to your hosting as either an addon or parked domain, you will not get another cPanel username or password. Each cPanel has a single username and password.
If you are on a VPS or Dedicated hosting plan, you can create a new cPanel account for that domain name. As you do that, you will get to assign it a cPanel username and password to be used exclusively for that cPanel account on your server.
