The only way(s) I can think of that you can do this is brute force it - which depending on the number of users and their level of sophistication may not be worth it (I have found that using dictionaries and some minor processing on a non-sophisticated user base that about 40% are crackable without breaking a sweat). The only other way is to capture the password when a user logs in and do whatever processing needs to be done at that point in time which is what I guess André was alluding to.

Yes, but as he mentioned edit handler I suggested looping the $_POST variable and find the password value when the user edits his profile. Just make sure you don't do anything when it is the default star values :)
