from .decorators import uthenticated_user
from app.models import *
# Create your views here.
#uthenticated_user
def login(request):
if request.method=='POST':
email=request.POST['email']
password=request.POST['password']
user=authenticate(request,email=email,password=password)
if user is not None:
login(request,user)
return redirect('user_home')
else:
messages.error(request,'There was a problem logging in. Check your email and password or create an account')
return redirect('login')
else:
return render(request,'registration/sign-in.html')

As i know, authenticate is only taking username and password. You can try to find username by email firstly and then authenticate him:
#uthenticated_user
def login(request):
if request.method=='POST':
email=request.POST['email']
password=request.POST['password']
# New code
try:
username = User.objects.get(email=email).username
except User.DoesNotExist:
username = None
user=authenticate(request,username=username,password=password)
if user is not None:
login(request,user)
return redirect('user_home')
else:
messages.error(request,'There was a problem logging in. Check your email and password or create an account')
return redirect('login')
else:
return render(request,'registration/sign-in.html')
