Auth

In the world of web development, security is paramount. You need to protect your application and its users from unauthorized access and malicious attacks. Authentication and authorization are two fundamental security mechanisms that work together to achieve this goal.

Think of authentication as verifying who someone is, like checking their ID at the door of a club. Authorization, on the other hand, determines what they are allowed to do once they are inside, like whether they have access to the VIP area or the dance floor.
