Here's what I do:

Mark your "change password request" objects with a unique Id (I use 
UUID>>asString36).  Send an e-mail to the user with a URL which contains 
an ID encoded in its path.

Create a root component and implement initialRequest:.  This method gets 
the WARequest instance as an argument.  From that you can get the path 
elements (I think I use "request nativeRequest pathParts last" to get 
the last one).  Now you have the id so you can pull the change password 
request object out of your database.
