I just registered an account at Stack Exchange.com. So far I only joined two network sites (meta, and cross validated). I somehow understand how the login system works for the network sites. What I don't get is why I get automatically logged in although I explicitly logged out of all sites.
It goes like this: I log out explicitly of any site and of Stack Exchange.com. When I now click on 'log in' at Stack Exchange.com and choose 'log in with Stack Exchange account' it automatically logs in without asking for my password. The only thing I can do is to delete my browser history.
I find this very troublesome, since this makes using a shared or public computer (which I do from time to time) very unsafe.
Does anyone know what's up with this?
