How to use email and password for login in Django? ›

Authentication forms

By default, the UserCreationForm only takes the username and password fields (with its verification input). So, we can modify this by creating a new class called RegisterForm which extends the default form. Then, we specify the required fields to create a new user (email, username, and password).

As we all know the default User model in django uses a username to uniquely identify a user during authentication. If you need to replace this username field with other field lets say an email field then you need to create a custom user model by either subclassing AbstractUser or AbstractBaseUser.

You have to declare the email field in your AbstractBaseUser model as unique=True .

For using email/username and password for authentication instead of the default username and password authentication, we need to override two methods of ModelBackend class: authenticate() and get_user():

{% %} and {{ }} are part of Django templating language. They are used to pass the variables from views to template. {% %} is basically used when you have an expression and are called tags while {{ }} is used to simply access the variable.

Sending Emails with the Django Shell

If you want to use django's default authentication backend you cannot make username non unique. You will have to implement a class with get_user(user_id) and authenticate(request, **credentials) methods for a custom backend.

Reason 1: Email is not a guaranteed unique identifier

Email is a means of contacting its owner/recipient. It is no different than a telephone number. Institutions may not enforce that multiple individuals not use the same email address when communicating with the institutions (domestic partners, siblings, etc.

How do I create a unique email name? ›

By not forcing the unique email constraint, you are more prone to having duplicates in your database which may cause other issues down the road if they aren't resolved.

Authentication factors can be classified into three groups: something you know: a password or personal identification number (PIN); something you have: a token, such as bank card; something you are: biometrics, such as fingerprints and voice recognition.

The include tag allows you to include a template inside the current template. This is useful when you have a block of content that is the same for many pages.

Django is an undeniably valuable tool in any developer's skill set — but getting started with it can be challenging. In the below sections, we'll share everything you need to know before you learn Django, as well as the framework's history, structure and setup.

The extends tag is used to declare a parent template. It should be the very first tag used in a child template and a child template can only extend up to one parent template. To summarize, parent templates define blocks and child templates will override the contents of those blocks.

from django.contrib.auth import authenticate, login def my_view(request): username = request.POST['username'] password = request.POST['password'] user = authenticate(request, username=username, password=password) if user is not None: login(request, user) # Redirect to a success page. ... else: # Return an 'invalid ...

Django is a Python-based web framework giving developers the tools they need for rapid, hassle-free development. You can find that several major companies employ Django for their development projects. Here are 9 global companies using Django: Instagram.

Email providers, like Gmail, allow you to drag an image from a folder and drop it into an area inside the compose box that says “attach files here”. Gmail will automatically embed the image and realign it so it's in line with the rest of the plain text.

Avoid using the beginning of your email address as your username. Your username should be simple enough to remember but hard to guess. Never use easy-to-guess numbers with your usernames (for example, address or date of birth). Don't use your Social Security number or ID number as your username.

How to create a custom user in Django? ›

An id field is added automatically, but this behavior can be overridden. See Automatic primary key fields. The CREATE TABLE SQL in this example is formatted using PostgreSQL syntax, but it's worth noting Django uses SQL tailored to the database backend specified in your settings file.

Most people think email names and email usernames are the same things. They're not. An email name (also known as a sender name) is the name that's displayed when you send an email. Your email username, however, is your email address.

If you need an account on a site that you don't want associated with your online reputation, don't use your real name or a common derivative of it. You want to avoid having a Google search of your name lead to these profiles. Try to pick something completely unrelated to your name that you'll be able to remember.

The UserName property holds the name of the user account under which the specified application process is running.

Email Address Tips

Do not use info@. That is an email address that spammers target. Instead, think of something more creative: hello@, contact@, letstalk@. Anything but info@, which will increase your spam levels exponentially!

Yes, you can use email address as Primary Key in databases. Because it is already an unique one. Thats why it is used as Username also in most webapplications.

Yes, it is a bad primary key because your users will want to update their email addresses. Save this answer. Show activity on this post. Another reason why integer primary key is better is when you refer to email address in different table.

Amanda Hesser and Merrill Stubbs, co-founders of Food52, once commented that adding “just” to your emails makes you seem less confident. After taking a look at previous emails I've sent, I really have to agree. Saying things like, “Just checking in” or “Just wanted to ask a question” minimizes your request.

Password-based authentication

Also known as knowledge-based authentication, password-based authentication relies on a username and password or PIN. The most common authentication method, anyone who has logged in to a computer knows how to use a password.

Passwords are the most common methods of authentication. Passwords can be in the form of a string of letters, numbers, or special characters. To protect yourself you need to create strong passwords that include a combination of all possible options.

Common biometric authentication methods include fingerprint identification, voice recognition, retinal and iris scans, and face scanning and recognition.

What is the strongest authentication method? ›

1. Biometric Authentication Methods. Biometric authentication relies on the unique biological traits of a user in order to verify their identity. This makes biometrics one of the most secure authentication methods as of today.

Biometric authentication is the strongest form of authentication.

Authorization. Authentication and authorization are two vital information security processes that administrators use to protect systems and information. Authentication verifies the identity of a user or service, and authorization determines their access rights.

The Django authentication system handles both authentication and authorization. Briefly, authentication verifies a user is who they claim to be, and authorization determines what an authenticated user is allowed to do. Here the term authentication is used to refer to both tasks.

Django provides several validation methods for checking email address validity. The easiest way is to import the validate_email method from the core validators module. This is a standalone function that can be used in any models, forms, or views.

Create an app folder in the django project folder. Add template folder in the django folder and provide its path in django_folder > settings.py . Create file named as urls.py in the app folder and provide its path in django_project > urls.py. Add login decorator to the function in app_folder > views.py.

validate(self, password, user=None) : validate a password. Return None if the password is valid, or raise a ValidationError with an error message if the password is not valid. You must be able to deal with user being None - if that means your validator can't run, return None for no error.

Can we create user without password in Django? ›

Programmatically, you can create / save a new User without a password argument, and it will not raise any exceptions. In fact, you can even create a user without any arguments.

Even though the username field is marked as unique, by default it is not case-sensitive.

The default User model in Django uses a username to uniquely identify a user during authentication. If you'd rather use an email address, you'll need to create a custom User model by either subclassing AbstractUser or AbstractBaseUser .
