there is a module Password Expire http://drupal.org/project/password_expire that seems to overlap some features of this module.
Shouldn't that module be integrated here?
If not; I think it should be wise to mention the existence of that module here and argue the differences.
Same issue for some other password modules that seem or might overlap; integrate them all? If not; document the differences on this project page?
It's for every user every time again an enormous lot of work to find out which password modules should be used, if there is not an explanation about the differences. And easiest for many new users would be just one module that has it all...
Same for password_change http://drupal.org/project/password_change for more security; Drupal would be more user friendly if this all is in one module
