title: Django form 'autocomplete'='off' does not work
body: <p>I've seen lots of answers on SO and none of them works in my case. My model form looks as follows:</p>
  
  <pre><code>class ChangePasswordForm(forms.Form):
      current_password = forms.CharField(
          max_length=64,
          widget=forms.PasswordInput(
              attrs={'placeholder': 'Current Password', 'autocomplete': 'off'}))
  
      new_password = forms.CharField(
          min_length=6,
          max_length=64,
          widget=forms.PasswordInput(
              attrs={'placeholder': 'New Password', 'autocomplete': 'off'}))
  
      confirm_password = forms.CharField(
          min_length=6,
          max_length=64,
          widget=forms.PasswordInput(
              attrs={'placeholder': 'Confirm New Password', 'autocomplete': 'off'}))
  </code></pre>
  
  <p>Still current_password, new_password and confirm_password are populating on the form. I've checked on Safari and Google Chrome and I still have the same issue. Can anyone tell me what am I doing wrong?</p>
