WW, 2 questions.

1. Is this authentication based off of IP address? If my IP address changes, will it get all screwed up? I think it's based purely off of cookies and IP address won't matter as long as you have the cookie on the machine, just wanna make sure.

2. How long does authentication last? Does it have to be renewed or anything like that? If I set it to work at home, and I go to work and log in and then log out, will I still have access at home? I think as long as cookies stick around authentication will stay as well, and since logging out clears your cookies, logging out at work would only clear my cookies at work.

Thanks.
