Authentication and authorization are two fundamental concepts in the realm of security, especially in computer applications.
Authentication- Authentication is the process of verifying the identity of a user, device, or entity in a computer system.
- Purpose- To confirm the identity of the user or entity.
Authorization- Authorization is the process of determining what an authenticated user is allowed to do. It specifies the permissions for resources in the system.
- Purpose- To control access to resources and actions based on user privileges.
There are lot of way to perform this in application like OAuth2.0, OIDC But all of these are paid platform for large number or advance services.
So, To achieve these Services without any cost keycloak come in the picture.
