Can't log in to the webgui using unraid docker

Ive been able to login as “nobody” with password “mineos” but was wondering if i could either change this to something else with root privileges or if there is another login I could use/make?

There should be an account called mc by default that you may have created a password during installation. You can create any account with sudo privileges and it will work fine. The new account won’t have access to any other account unless you add it to the mc group.
