Can I use an email instead of a username to log in?

Yes, but Django's default User model forces the username field. To use email as the primary login, you must create a Custom User Model by inheriting from `AbstractUser` or `AbstractBaseUser` before running your very first database migration.

How do I log a user out?

Simply import and call the `logout(request)` function in your view. This function will completely destroy the session data on the server and delete the session cookie from the user's browser.

What is a Session Cookie?

A cookie is a tiny text file stored in the user's browser. Django generates a random 'Session ID' (e.g., 'xyz123') and saves it in the cookie. Every time the user clicks a link, their browser sends that ID back to the server, allowing Django to remember who they are.
