How do I implement claims-based authentication in ASP.NET MVC?

To implement claims-based authentication in ASP.NET MVC, you can use the built-in Identity framework. First, ensure you have the necessary packages installed.

What are claims and how do they differ from roles?

Claims are key-value pairs associated with a user, providing specific information about them, while roles are broader categories that define a user's permissions.

Can you show me a code example for adding claims?

Sure! You can add claims like this: var claims = new List<Claim> { new Claim("ClaimType", "ClaimValue") }; and then create a ClaimsIdentity.

How do I access these claims in my controllers?

You can access claims in your controllers using User.Claims or User.FindFirst("ClaimType") to retrieve specific claims.
