Going through my own inbox for Facebook emails, it attaches my email address in the n_m parameter, the bcode parameter, and a mid parameter to all the links it gives me. This includes links to my friends' profiles, events, group posts, etc.

As far as an expiration on the auto-login, I rarely click on the links Facebook provides in my email. (I like to get the notification to remind me to go on Facebook later.) The last one I got was about 25 hours ago. I didn't use the link before and it did not log me in when I clicked it just now.
