Remove password field from user registration form

Question

I don't want the password field to be a required user registration field. How can I remove the password field? Is this done by changes in user.module file?

Answer 1

Just Enable "Require e-mail verification when a visitor creates an account." in "admin/config/people/accounts" page. That will remove password fields and provide you extra security also ..

Answer 2

You can use Generate Password module to achieve this goal. This module makes the password field optional (or hidden) on the add new user page (admin & registration). If the password field is not set during registration, the system will generate a password. You can optionally display this password at the time it's created.

For more info go through the documentation of this module.

Answer 3

You need to write form_alter

 function MODULE_form_alter($form, &$form_state, $form_id){
    if ($form_id == "user_register_form") {
          $form['account']['pass']['#access']  = FALSE;

    }       
    return $form;
 }

in your form_submit you can not save blank password in DB so while saving create one temporary password

        $password = user_password(8);

and pass it in user_save. You may also need to alter the validation hook.

Hope this will help you

To add to @CodeSurfer's answer, you can generate a password on the form_alter.

function MODULE_form_alter($form, &$form_state, $form_id){
     if ($form_id == "user_register_form") {
        $form['account']['pass']['#type'] = 'value';
        $form['account']['pass']['#value'] = sha1(user_password());
     }
