A Django Blog In VS Code — Self-Service Django Password Reset
How To Create A Blog in VS Code — Part X — DjangoSeries Episode # 13
How do you implement password reset functionality for regular site users?How do we make a password reset page?
In this tutorial, we will use the Django Password Reset Form to allow users to reset their own passwords using the self-service password reset tool. This allows users to reset their passwords as needed.
We will take a look at configuring the Google SMTP service provider and finally how to use the send_mail() function in Django which helps us send emails.
Here’s the user and server communications in graphic:

Motivations
Self-service password reset eliminates the need to talk to a service provider and users have access to it regardless of the time of day, password self-service is typically available 24/7 via desktop or mobile devices; self-service password reset expedites problem resolution for users and thus reduces service desk call.
Let’s get started!
Here is my Django Conventions Table:
What we want is a password_reset page where the user can enter their email address, and be sent a cryptographically secure email with a one-time link to a reset page
This is the complete set of views and URLs provided by the Django auth app:
accounts/login/ [name='login']
accounts/logout/ [name='logout']
accounts/password_change/ [name='password_change']
accounts/password_change/done/ [name='password_change_done']
accounts/password_reset/ [name='password_reset']
accounts/password_reset/done/ [name='password_reset_done']
accounts/reset/<uidb64>/<token>/ [name='password_reset_confirm']
accounts/reset/done/ [name='password_reset_complete']We will only be using the last four URLs related to password reset.
00#Step — This is a continuation of this post.
PASSWORD_RESET — : Modus operandi V(iew) U(rls) T(emplate)
01#Step — V(iew): Django already has all the views as CBVs:
django.contrib.auth.PasswordResetView
django.contrib.auth.PasswordResetDoneView
django.contrib.auth.PasswordResetConfirmView
django.contrib.auth.PasswordResetCompleteView02#Step — U(rls): GoTo django_project\urls.py, and add these lines:
from django.contrib.auth import views as auth_views
...urlpatterns = [
...
path('password_reset/', auth_views.PasswordResetView.as_view(template_name="users_hub/password_reset.html"), name='password_reset'),
...
]
03#Step — T(emplate): Create inside a template user_hub\templates\user_hub\password_reset.html, and add these lines:
PASSWORD_RESET _DONE— : Modus operandi U(rls) T(emplate)
This next route is just going to be the page for when our password reset form is submitted successfully (2 IN GRAPH)
04#Step — U(rls): GoTo django_project\urls.py, and add these lines:
from django.contrib.auth import views as auth_views
...urlpatterns = [
...
path('password_reset_done/', auth_views.PasswordResetDoneView.as_view(template_name="users_hub/password_reset_done.html"), name='password_reset_done'),...
]
05#Step — T(emplate): Create inside a template user_hub\templates\user_hub\password_reset_done.html, and add these lines:
PASSWORD_RESET _CONFIRM — : Modus operandi U(rls) T(emplate)
06#Step — U(rls): GoTo django_project\urls.py, and add these lines:
from django.contrib.auth import views as auth_views
...urlpatterns = [
...
path('password_reset_confirm/<uidb64>/<token>/', auth_views.PasswordResetConfirmView.as_view(
template_name='users_hub/password_reset_confirm.html'), name='password_reset_confirm'),
...
]
Just be aware of these points:
1- <uidb64> is the user’s primary key encoded using the secret key in settings; it stands for User ID urlsafe_base64_decode;
2- <token> it’s an instance of django.contrib.auth.tokens.PasswordResetTokenGenerator;
3- We will have to accept those URL parameters there because it expects those so now the view that we want to.
07#Step — T(emplate): Create inside a template user_hub\templates\user_hub\password_reset_confirm.html, and add these lines:
PASSWORD_RESET _COMPLETE— : Modus operandi U(rls) T(emplate)
08#Step — U(rls): GoTo django_project\urls.py, and add these lines:
from django.contrib.auth import views as auth_views
...urlpatterns = [
...
path('password_reset_complete/', auth_views.PasswordResetCompleteView.as_view(
template_name='users_hub/password_reset_complete.html'), name='password_reset_complete'),
...
]
09#Step — T(emplate): Create inside a template user_hub\templates\user_hub\password_reset_done.html, and add these lines:
10#Step — T(emplate): Create inside user_hub\templates\user_hub\password_reset_done.html, and add these lines:
Here is the complete django_project/urls.py:
11#Step — Let’s try to run the server and see what’s going on…Type on Terminal:
python manage.py runserver
Let Google know to expect sign-ins from a Python application
12#Step — GoTO django_project/settings.py, and at the very end, type:
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'EMAIL_HOST = 'smtp.gmail.com'EMAIL_PORT = 587EMAIL_USE_TLS = TrueEMAIL_HOST_USER = os.environ.get('EMAIL_USER')EMAIL_HOST_PASSWORD = os.environ.get('EMAIL_PASS')
Note:
Invalid login: 534–5.7.9 Application-specific password required.If you receive this error when attempting to connect your inbox to the platform it indicates that you have 2 factor authentication enabled under the inbox you are attempting to connect, and will need to create an App password under your Google account in order to get it connected to the platform. In order to create an app password, please follow our guide on how to do this here.
13#Step — Again, Point your browser URL to:
http://127.0.0.1:8000/password_reset/You would see:
Just one more thing that we need to do we haven’t actually created a link anywhere.
Just do it!
14#Step — GoTo the login template and put that there:
Right after the submit button:
<div class="form-group"><button class="btn btn-outline-info" type="submit">Login</button> <small class="text-muted ml-2">
<a href="{% url 'password_reset' %}">Forgot Password?</a>
</small></div>
And here is the result:
Ok, at that point the user would go through that whole process.
Finally in the next tutorial we will upload our project to HEROKU.
Do not miss your chance to be the next Django Webmaster!
See you around. Bye!
