My school's wifi network is open, but requires a login with student account name/password in the browser.
What confuses me is that it asks for this login every time the network is accessed (or every few hours while continuously connected). Is there a reason it has to do that? Why can't the network just remember my computer/phone and let it in every time? (And if this has to do with the browser login, I'm pretty sure I've used similar logins in the past in hotels, and those networks remembered my devices)
Is this set-up due to a security concern?
