That's a very interesting one, and a somewhat difficult appraisal to make accurately.
It's not about a physical item (unless you make it about the boardgame), like a pass-key or movie pass, etc., it's about a virtual item, a secret code that gets you past some barrier. And it's about a virtual item that is difficult to pin down a use for, domain name-wise...
Could be dev'd with some script into an internet tool that helps to invent random good passwords, or as a tool to help hacks crack other peoples' passwords, or you could start thinking laterally and use that name for a site selling or reviewing word processors, or even anything about domain names since there's the word 'word' in there. But I agree with Etab above, I think his suggestion for dev is the strongest.
In other words, a lot of uses but they're all nebulous, no direct meaning/use is spelled out for this word so it's one any domainer/end user has to think about considerably before buying.
That's a two-sided coin of course, because a name with a lot of possible uses can also appeal to a wide variety of buyers.
I like it a lot. Password is used all over the net, every single day, by almost every user, so it's an extremely common and relevant word; the dot.us extension lessens the overall value, but streamlines the possible uses to anything-American so in that way helps to pinpoint the users and clarifies some value.
I'll appraise it as a domain name without content:
to a reseller, I'd say in the range of high xxx to low x,xxx, but wouldn't be surprised if they liked it enough for considerably higher, since it's such a well-used word daily.
to an end user I'd hazard a higher estimate and very large range, anywhere from low x,xxx to high x,xxx simply because it's such a usable word if you've got the right use for it; if you get a motivated end user that has some size to them, of course you go up into the higher brackets of my estimate.
Hope that helps a little
