That was a recent change (http://code.djangoproject.com/changeset/13498) and
is why I pointed to the 1.2 docs instead of the dev ones in answering. For
anyone using an official release, it is necessary to pass render_value=False
to get the desired behavior; for anyone using current trunk, it is not
necessary but also not harmful. For a while it will be safest for anyone
really desiring this behavior to pass render_value=False, that way the code
will work as intended on both current and older levels of Django.

Oh sorry, the documentation is correct in the development docs:

http://docs.djangoproject.com/en/dev/ref/forms/widgets/#django.forms.PasswordInput

Note that the docs indicate the default value for render_value is True
but in the code it is False:

http://code.djangoproject.com/browser/django/trunk/django/forms/widgets.py#L232

Use this widget for the field:

http://docs.djangoproject.com/en/1.2/ref/forms/widgets/#django.forms.PasswordInput

with render_value=False
