Using built in ASP.NET membership to secure web services.

Is it possible to use the built in ASP.NET membership provider to secure a web service?

I have a SQL Server database already setup with my membership and now I want to provide a web service that only members are allowed to use. Is it possible to authenticate against this (if so how?) or do I need to have a seperate type of authentication for the web services?

From stackoverflow

• definitely possible. you can use ASP.NET membership provider in conjunction with WCF (i used this for a project last year). and (thats the fun part) its merely just some configuration you have to do. it also works with ASP.NET RoleProvider´s

• I think that I can do something like this. I didn't have a server to upload and test right now, but will mark this as the answer if it works:

      [WebMethod]
      public string HelloWorld(String username, String password)
      {
          bool isAuthenticated = Membership.ValidateUser(username, password);
  
          if (isAuthenticated)
              return "Hello World";
          else
              return "You do not have access to this resource.";
      }
