Hi Axel,
An installed application and a registered URL namespace are two distinct
concepts. A URL namespace can only be defined by setting the app_name
attribute in your urlconf. In this case, you haven't set a URL namespace
for your authentication app, so your urls are not namespaced.
Also, the urlconf parameter to reverse() should point to the root urlconf,
not to the urlconf in which your current url is defined. Since it defaults
to the root urlconf defined in your project, it's easiest to omit it in
most cases. If you don't, and use 'authentication.urls' as your root
urlconf, the generated url will miss the 'authentication/' part of your
url.
To reverse the password_change url, simply use this:
reverse('password_change')
