When you first connect an open Wi-Fi network such as a public one you are often greeted by a webpage which asks for some login information or sign-up details before you can proceed to use the internet. This is commonly called a splash page, hijack page or more correctly a ‘captive portal’ and is used to control access to the internet. These pages may be branded with logos and sponsor information and typically offer one of three types of access:
- Open access with just a ‘click to accept terms and conditions’
- Open access after entering some basic information such as an email address
- Authenticated access using a code or username/password approach
Post login the user may be redirected to a ‘landing’ page (often a page the provider wants to promote) or directed onwards to the original requested page.
