I conceive that people don't usually have multiple passwords since if they do set a new password, chances are they forget the old password and either 1. they can't recall the old password anymore 2. they re-encrypt old chatlogs with new password. Either case, they won't be entering old passwords when searching.

I agree multiple popups are quite annoying and if there is really a need to have the user enter multiple passwords, the better way should be increasing the number (which is not fixed and can grow dynamically) of textboxes for passwords in the popup window when the search is to begin.
