The Full Stack Web Development - Access Control & Logout

The video tutorial covers implementing access control in a web application using authentication. It begins with creating a function to ensure users are authenticated before accessing certain routes. The tutorial then demonstrates how to display user information by setting up global variables through middleware. It also covers implementing a logout feature with flash messages to inform users of successful logout. The video concludes with a summary of the complete login system using Passport, highlighting its integration into any application requiring authentication.
