There are many ways to authenticate and authorize API requests in an ASP.NET MVC application. Here are a few common methods:

  • Basic authentication is a simple method that uses a username and password to authenticate users. The username and password are sent in clear text over the network, so this method is not very secure.
  • Digest authentication is a more secure method than basic authentication. It uses a hash of the username and password to authenticate users. The hash is not sent in clear text over the network, so this method is more secure than basic authentication.
  • OAuth is an authorization framework that allows users to grant third-party applications access to their data. OAuth is a more secure and flexible method than basic or digest authentication.
  • Token-based authentication is a method that uses tokens to authenticate users. Tokens are short pieces of data that are generated by the server and sent to the client. The client then sends the token back to the server with each request. This method is more secure than basic or digest authentication because the tokens are not sent in clear text over the network.

Once a user has been authenticated, you can use authorization to control which resources they can access. Authorization can be based on the user's role, group, or other criteria.

Here are some common ways to implement authorization in ASP.NET MVC:

  • Attribute-based authorization uses attributes to control access to resources. The attributes are applied to the controller actions or methods that you want to protect.
  • Role-based authorization uses roles to control access to resources. The roles are assigned to users, and you can use the roles to control which resources users can access.
  • Claims-based authorization uses claims to control access to resources. Claims are statements about a user, such as their name, email address, or role. You can use claims to control which resources users can access.

The best method for authenticating and authorizing API requests in an ASP.NET MVC application will depend on your specific requirements. You should consider the security requirements of your application, the number of users, and the complexity of your authorization needs.
