this isn't unix :) the single most-important reason to switch users (do something as root) does not exist here, hence nobody bothered. when you set up a proper file/cpu/auth server on which you're going to have more than one users then you can always log in as the administrative user (bootes, in most cases) remotely or on the console of the server and administer. if you only have a standalone, single-user machine you're considered its owner. in short, you'll need to set-up a standalone cpu/auth server to get passwords. the instructions are on the wiki. have you read "plan 9 from bell-labs" and "security in plan9"? they contain some of the rationale for this setup.
