Q.What is superlogout?.

Superlogout : a website you can use to instantly logout of all active online accounts
If you visit a Internet Cafe for surfing, use public Wi-Fi or have this odd habit of logging out of all online accounts at the end of each day. We bring to you a website called Superlogout.

Superlogout which can be visited here (be warned you get logged out instantly from all online accounts) is a great tool for people who surf the Internet using public Wi-Fi or Internet Cafes.

Q.what does superlog does?

As soon as you visit Superlogout, it will automatically get to work logging you out of a few dozen major services including Amazon, Google, Netflix, Steam, Tumblr, and YouTube. Once you’re logged out, the site will display a green “OK” next to each service.

For some reasons the developer of Superlogout has not included Facebook, but it’s a quick way to log out of many sites at once.
Logging out of your account when you’re done using a computer other than your own is just good security. If you use multiple accounts and want to simplify the process, Super Logout can log you out of over 30 major services at once.
As soon as you visit the site below, it will automatically get to work logging you out of a few dozen major services including Amazon, Google, Netflix, Steam, Tumblr, and YouTube. Once you’re logged out, the site will display a green “OK” next to each service. The list isn’t comprehensive (notably, Facebook is absent), but it’s a quick way to log out of many sites at once.

Q.how does it work?

It’s actually pretty clever. The “keep me logged in” feature you see on many websites is made possible by allowing websites to store a very small amount of private data within your browser, in the form of “cookies”. When I first came across Super Logout, I wondered if maybe the creator had figured out some way to exploit the browser such that it would delete the cookies stored by other websites, but that’s not how it works.

I read through the javascript to see how it does:

  • A big array of websites and their corresponding “log me out” URLs:
  • A couple of functions which are called from a loop in order to load every URL in the above list
  • A CSS class called “hidden”, which is used to hide all the additional websites being loaded within iframes and <img> tags by the functions above:
NOTE: it’s not exploiting any security vulnerabilities; it’s telling your browser to go fetch each URL in a carefully-crafted list and load it in a tiny page element hidden slightly outside of the upper left corner of the window and log out off all the website ie deleting the cookies stored in the browser’s preference list
