Lecture 365:- Authentication and Authorization
Authentication and authorization are two important concepts in web development. They are often used together to control access to resources on a web application.
Authentication is the process of verifying the identity of a user, typically through a username and password. When a user logs in to a web application, the application will authenticate the user by verifying their credentials against a database of registered users. Once the user has been authenticated, they are typically issued a token or session ID that is used to identify them in subsequent requests.
Authorization, on the other hand, is the process of determining whether a user has access to a particular resource or action within the web application. Once a user has been authenticated, the application will use their token or session ID to determine what resources they are authorized to access. This is typically done by comparing the user's permissions to the permissions required for the resource or action in question.
In summary, authentication verifies a user's identity, while authorization determines what resources or actions they are allowed to access.
