Underneath the covers, role-based authorization and claims-based authorization use a requirement, a requirement handler, and a pre-configured policy. These building blocks support the expression of authorization evaluations in code. The result is a richer, reusable, testable authorization structure.

Adding role checks. Role based authorization checks: Are declarative. Are applied to Razor Pages, controllers, or actions within a controller.

Read more on the official docs: Role-based authorization in ASP.NET Core. Claims-based authorization# In claims-based authorization, we still use the [Authorize] attribute. The difference now is that we provide a Policy name/string to it. The policy is statically configured and, at the minimum, it verifies if the logged-in user has a claim of

Claim-based authorization checks: Are declarative. Are applied to Razor Pages, controllers, or actions within a controller. Can not be applied at the Razor Page handler level, they must be applied to the Page. Claims in code specify claims which the current user must possess, and optionally the value the claim must hold to access the requested

Differences Between Role-Based and Claim-Based Authorization in ASP.NET Core Identity: Scalability: Claims-based authorization scales better in more complex and dynamic environments. Management: RBAC is easier to manage in simpler systems, while claims-based is more suited for environments where user attributes and context are critical

Role-based claims authorization in ASP.NET Core Identity is a powerful way to manage user access in an application. It combines the simplicity of Role-Based Authorization with the flexibility of Claims-Based Authorization. This approach allows us to assign roles to users and then use claims to specify the permissions or capabilities of those roles.

https://dotnettutorials.net/lesson/claims-based-authorization-in-asp-net-core-identity/
This is usually done using attributes like [Authorize (Policy = "PolicyName")]. So, in ASP.NET Core Identity, a claims policy implements authorization based on claims associated with the current user. Claims are key-value pairs associated with a user and represent properties of the user, such as their name, role, email, or any other custom

Roles vs Claims vs Policy A role is a symbolic category that collects together users who share the same levels of security privileges. Role-based authorization requires first identifying the user, then ascertaining the roles to which the user is assigned, and finally comparing those roles to the roles that are authorized to access a resource.

Authorization Policy. Authorization Policies are the backbone of the ASP.NET Core Authorization Framework. Even when you use claim-based or role-based authorization, you are actually using Policy-based Authorization. A Policy defines a collection of requirements, that the user must satisfy in order to access a resource.

Let's see how we can use the role-based authorization in the asp.net core web app. In the Program.cs file, we have the following line indicating the default identity is added to the application (this is added to my project by default because I've created a brand new one with Individual Accounts)

Authorization types. ASP.NET Core authorization provides a simple, declarative role and a rich policy-based model. Authorization is expressed in requirements, and handlers evaluate a user's claims against requirements. Imperative checks can be based on simple policies or policies which evaluate both the user identity and properties of the

This line begins configuring the authentication services within the ASP.NET Core dependency injection system. The string "BasicAuthentication" specifies the application's default authentication scheme. This is useful when multiple schemes are present, and you want to set one as the application's default.

Using roles without claims. To use roles without claims, there are a couple of changes we would need to make. Regarding adding the user to a role upon registration, the code would be very similar: 1 2 3. var addClaimResult = await _userManager.AddClaimAsync(user, new Claim(ClaimTypes.Role, "admin"));

Claim-Based Authorization in ASP.NET Core MVC Views. Implementing claim-based authorization in ASP.NET Core MVC views involves checking for specific claims within the current user's identity and then rendering content based on the presence or absence of these claims. This can be done directly in the Razor views.

There is a a great explanation video of Barry Dorrans, talking about the advantage of using claims over roles. He also states that roles, are still in .NET for backward compatibility.
