title: password field data gets clear after submitting
body: <p>I am uisng Django's <code>auth_user</code> table for username and password.To change the password field i did the below in forms.py</p>
  
  <pre><code>class UserRegisterForm(forms.ModelForm):
      password = forms.CharField(widget=forms.PasswordInput())
      class Meta:
          model = User
  </code></pre>
  
  <p>After changing my password field widget to <code>PasswordInput</code>,whatever password i enter gets cleared if i press save button.I tested it,the data gets saved in db,i am able to login using the same username and password.</p>
  
  <p>template.py</p>
  
  <pre><code>&lt;tr&gt;
      &lt;td&gt;Password&lt;/td&gt;&lt;td&gt;{{registerform.password}}*                                
  &lt;/tr&gt;
  </code></pre>
  
  <p>Clarification:Before changing the password widget,the value entered are displayed in the field as same and not cleared in the field if i save.</p>
  
  <p>After changing the password widget i am getting this issue.Password is showing in bullet point symbol but if i hit save button,entered password gets cleared from that field(field become empty but it is saving in model)</p>
  
  <p>What would be the problem for this.</p>
  
  <p>Thanks  </p>
