If I am understanding what you are doing, I'd be able to change someone
else's password if I knew the page to visit.  If you give me a public URL to
test I can show you how.  :)

That may be, but it's not really an accurate representation of what you are
doing.  If you are sending it via email, I could see it getting double
URLencoded perhaps...  To simulate your problem, you might try saving the SK
as a session var too, then going through the entire email process, clicking
the link in the email, and THEN outputting and comparing the session SK with
the URL SK values.

I am not sure what the difference would be, but doing that would likely
expose it to you.
