What is Authorize attribute?

The 'Authorize' attribute in an ASP.NET application is a powerful tool that helps us to have full control over who can access the resources in our ASP.NET MVC application and who can not. If someone who is not authenticated for access and tries to access action or controller that are under Authorize attribute, will be redirected to either the login page or an appropriate access-denied page.

Authorize Attribute Properties:

PropertiesDescription
RolesGets or sets the roles required to access the controller or action method.
UsersGets or sets the user names required to access the controller or action method.
