I am looking for an implementation similar to that of what is seen on banking sites. If a user comes to the site I want them to have to pass some form of registration IE (answer a question or enter in some key). If the user closes the browser and comes back to the site again from that machine they would just be able to provide login credentails to get in.
I am not sure if this is accomplished in ASP.NET by a cookie or what type of implementation. Any insight or examples of something similar would be greatly appreciated.
