It would probably be just as easy to use a plain field as a Validator for what you describe. Say you have a field named "myfield". You could then have a button with a script something like:

on click do
 if myfield.text ~ "the password"
  go[someOtherCard]
 end
end

Or perhaps you could give the field a script and enable a button when it contains the correct text?

on change val do
 myButton.locked: !val~"the password"
end

This thread has some additional discussion about implementing a password/search system that might be useful.
