Answer 1

save this content in forms.py

from django import forms
from django.contrib.auth.forms import AuthenticationForm
from django.forms.widgets import PasswordInput, TextInput


class MyAuthForm(AuthenticationForm):
    class Meta:
        model = User
        fields = ['username','password']
    def __init__(self, *args, **kwargs):
        super(MyAuthForm, self).__init__(*args, **kwargs)
        self.fields['username'].widget = forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'Username'})
        self.fields['username'].label = False
        self.fields['password'].widget = forms.PasswordInput(attrs={'class': 'form-control', 'placeholder':'Password'}) 
        self.fields['password'].label = False

and save this content in main urls.py

from users.forms import MyAuthForm

urlpatterns = [
   ...
   path('', auth_views.LoginView.as_view(template_name='users/login.html', authentication_form=MyAuthForm), name='login'),
   ...
]
