title: Accessing WiFi internet that has additional authentication
body: <p>My university runs their wifi authentication in a 2-step process. First you connect to the wifi network and then when you open a web browser, you have to type in some additional information about yourself to access the internet.</p>
  
  <p>1) The university system has some way of detecting whether a device has been previously authenticated (so it doesn't ask you everytime for credentials), how is this done? Is it by MAC address?</p>
  
  <p>2) Suppose I'm trying to run a home server that doesn't have a web browser. How can I get to the internet? Do I need to install a web browser to go through the 2nd step of authentication?</p>
