What is the ‘super user’ in Matomo?

Super Users are the only users that can perform all administrative tasks such as adding new websites to monitor, adding users, changing user permissions, activating and deactivating plugins and even installing new plugins from the Marketplace.

By default in Matomo (Piwik) there is one super user which was created during the installation process. As of Matomo 2.1, you may give Super User permission to other users.

The Super User has superpower!
