"If the password is invalid, authenticate() returns None" [1]
The password field in the User model contains "...a hash of, and
metadata about, the password. (Django doesn't store the raw password.)" [2]
So authenticate is returning None because you're trying to login with a
hashed version of the password, not the raw version. Try this instead:
user = authenticate(username=username, password=password)
Look at the second code example under [1] for an example of how to do this.
