koahana auth module: get unhashed user password value

Question

I have a form to allow a user to edit their details however the password associated to the user model is hashed. What is the best way to unhash this so I can add it to the form?

// get user
$user = ORM::factory('user', $id);

// in the form
<input id="password" type="password" name="password" value="<?php echo $user->password; ?>" />

Answer 1

You can't unhash a hash. That's the point of the hash. This is a bad idea. You should never repopulate or email someone their password.

Answer 2

Think of a hashed password as a one way street. It is okay to go down it one way but not the opposite way. I also agree with zombor that this is a bad practice.
