Remove personal password mac

Hi I am wondering how to diasable password based access on the Mac client so that the only way to connect for unattended access is via my account.  I am able to grant easy access, and i can disable the random password, but I have been unable to disable the personal password.  Instructions on the forum seem to reference the steps on Windows, but I don't see the same options on Mac. Simply leaving the personal password fields blank does not seem to be allowed.
