Super Logout Logs You Out of Dozens of Services at the Same Time
Logging out of your account when you’ve finished using a computer other than yours is just good security. If you have multiple accounts and want to streamline the process, Super Logout can log you out of over 30 essential services at the same time.
Once you visit the site below, it will automatically start logging out of several dozen major services including Amazon, Google, Netflix, Steam, Tumblr, and YouTube. After logging out, a green OK button will be displayed next to each service on the site. The list is not exhaustive (Facebook is missing in particular), but it is a quick way to log out of many sites at the same time.
