In Matomo (Piwik), you can create an infinite number of users and websites to track. For each user, you can set permissions to “view”, “write”, “admin” or “no permission” for a specific website, or for all websites at once. The permission system in Matomo is simple and makes it very easy to manage from a small number of websites and users to hundreds of websites and thousands of users. Learn more in the Manage Users documentation.
