I understand what your saying, but if I just use the ID, then it makes it extremely easy to login as another user, simply change the ID in your cookie. Atleast if I have email/password aswell it takes someone with access to the network and a sniffer to get the values. If a user changes his email and/or password, then the cookie gets updated, simple. I can't see that its that much of an issue. If we were talking about a credit card number or something else critical then I'd agree. Jim.
