Answers.Text: Thanks for the response. Yeah they do work between the two systems, we've got that all working great. Crafts hashing system has been matched on the other side so users can use the same password between the two sites for a single sign-on set up. So it's less about importing a heap of existing users from another site, and the risk of them having to reset passwords, and more about keeping everything in sync.

Comments.Text: Why set the already hashed password when it's hashed for you? Is it from an import? If so, you need to make sure the has is the same and import it manually into the database, but that starts leaping into dangerous territory.

Comments.Text: That's right - it's importing from an external system to synchronise passwords. I don't have access to the users raw password, just the hashed password which is hashed using the same password hashing approach as Craft utilises. So it's not possible to save a hashed password without hitting the database directly?

  There’s no API for it; you would need to save it to the database directly.
  
  If any of the passwords are known to you, you should probably start by manually pasting that hashed password into your account’s password column, and verify that it’s actually going to work. Even if the old site was also using mcrypt, it’s still pretty unlikely that they get hashed the *exact* same way (different salts, etc.).
  
  If it doesn’t work out, and you really don’t want to require everyone to reset their passwords, you could save all of your hashed passwords in a separate table, and write your own "login" controller action using a plugin. That controller action could:
  
  * grab the user by their given username/email
  
    ```
    $loginName = craft()->request->getPost('loginName');
    $user = craft()->users->getUserByUsernameOrEmail($loginName);
  
    ```
  * see if that user has a row in your old hashed passwords table
  * if so, fetch their password from post...
  
    ```
    $password = craft()->request->getPost('password');
  
    ```
  * hash that password using the old site’s exact hashing method
  * if the hashed password matches the one in the table...
  * save the posted password on the user account
  
    ```
    $user->newPassword = $password;
    craft()->users->changePassword($user);
  
    ```
  * delete the user’s row in the old hashed passwords table (so we're only doing this once per user)
  * log the user in
  
    ```
    craft()->userSession->login($loginName, $password);
  
    ```
  
  (See craft/app/controllers/UsersController.php - actionLogin() for a full code example of `login()`.)
