Django: Trouble With Logging User Using Bootstrap Login.html

I'm using Django 3.0.2 + Boostrap. I have created a registration/login.html page. The contents of this page are shown below.

The page renders correctly and most of it works OK. However, I am unable to login to my website through this page. I keep getting Your username and password did not match. Please try again. I can login to the admin website without any issues if I use the same username/password. I am not sure what is wrong with my login.html. Any ideas?

{% extends "base.html" %}

{% block content %}

{% if form.errors %}
<p>Your username and password did not match. Please try again.</p>
{% endif %}

{% if next %}
    {% if user.is_authenticated %}
    <p>Your account does nohave access to this page. To proceed,please login with an account that has access.</p>
    {% else %}
    <p>Please login to see this page.</p>
    {% endif %}
{% endif %}

Your input types are missing the name attribute. As per the Mozilla docs:

A string specifying a name for the input control. This name is submitted along with the control's value when the form data is submitted.

So the name is submitted with the form. But what if there is no name attribute? Same Documentation explains:

Consider the name a required attribute (even though it's not). If an input has no name specified, or name is empty, the input's value is not submitted with the form.

So your username and password are not sent to the backend.

You need to provide the name attributes to your input types.

<form class="user" method="post" action="{% url 'login' %}">
      {% csrf_token %}
      <div class="form-group">
           <input type="text" class="form-control form-control-user" id="exampleInputUserName" placeholder="Username" `name="username"`>
       </div>
       <div class="form-group">
            <input type="password" class="form-control form-control-user" id="exampleInputPassword" placeholder="Password" name="password">
       </div>
       <input type="submit" class="btn btn-primary btn-user btn-block" value="Login">
       <input type="hidden" name="next" value="{{ next }}">
</form>

It is front-end issue, not particularly related to Django.
