Re: Cookies as the second factor

["Robin Wood" <dninja () gmail com>]

Javascript could be used to generate the cookie which is then passed
back to the server with each request. This would save having to make
sure a value was posted or passed on the query string on each request.

Don't have time to think about how good this would be for
authentication but I think techincally it can be done.
