How to allow users to change their own passwords in Django?

This tutorial shows how to do it with function based views:

View file:

from django.contrib import messages
from django.contrib.auth import update_session_auth_hash
from django.contrib.auth.forms import PasswordChangeForm
from django.shortcuts import render, redirect

def change_password(request):
    if request.method == 'POST':
        form = PasswordChangeForm(request.user, request.POST)
        if form.is_valid():
            user = form.save()
            update_session_auth_hash(request, user)  # Important!
            messages.success(request, 'Your password was successfully updated!')
            return redirect('change_password')
        else:
            messages.error(request, 'Please correct the error below.')
    else:
        form = PasswordChangeForm(request.user)
    return render(request, 'accounts/change_password.html', {
        'form': form
    })

Url file:

from django.conf.urls import url
from myproject.accounts import views

urlpatterns = [
    url(r'^password/$', views.change_password, name='change_password'),
]

And finally, the template:

<form method="post">
  {% csrf_token %}
  {{ form }}
  <button type="submit">Save changes</button>
</form>

Its without need to go to shell enter passwd and reenter passwd

 python manage.py changepassword <username> 
  or
/manage.py changepassword <username>

Using shell

python manage.py shell
from django.contrib.auth.models import User
users=User.objects.filter(email='<user_email>') 
  #you can user username or etc to get users query set
  #you can also use get method to get users
user=users[0]
user.set_password('__enter passwd__')
user.save()
exit()

This is the command i used, just in case you are having problem in that throw AttributeError: Manager isn't available; 'auth.User' has been swapped for 'users.User'.

python manage.py shell -c "from django.contrib.auth import get_user_model; 
User = get_user_model(); 
u = User.objects.get(username='admin'); 
u.set_password('password123');
u.save()"

Per the documentation, use:

from django.contrib.auth.hashers import makepassword

The main reason to do this is that Django uses hashed passwords to store in the database.

password=make_password(password,hasher='default')
obj=User.objects.filter(empid=emp_id).update(username=username,password=password)

I used this technique for the custom user model which is derived from the AbstractUser model. I am sorry if I technically misspelled the class and subclass, but the technique worked well.

Authentication is the one way and after that reset the password

from django.contrib.auth import authenticate
user = authenticate(username='username',password='passwd')
try:
  if user is not None:
     user.set_password('new password')
  else:
     print('user is not exist')
except:
  print("do something here")
