My urls.py looks like this:

from django.urls import path
from . import views
from django.conf import settings
from django.contrib.auth import views as auth_views
from django.contrib.auth.views import (
    login, logout, password_reset, password_reset_done, 
password_reset_confirm
)
from django.conf.urls.static import static

app_name = 'client'

urlpatterns = [
    path('register/', views.register, name='register'),
    path('login/', login, {'template_name': 'Clientes/login.html'}, 
name='login'),
    path('mail/', views.mail, name='mail'),
    path('profile/config', views.config_view, name="config"),
    path('profile/dashboard', views.dashboard_view, name="dashboard"),

    path('reset-password/', password_reset, name="reset_password"),
    path('reset-password/done/', password_reset_done, 
name="password_reset_done"),
    path('reset-password/confirm/', password_reset_confirm,

    path('profile/', views.ProfileView.as_view(), name='profile'),
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
