Login-based license management is enabled per production instance of your Tableau Server deployment. You only need one Tableau Server or Tableau Online site to authorize an individual Tableau Desktop or Tableau Prep Builder.
You only need to manage one or more product keys for on-premises Tableau Server, or in the case of Tableau Online, you don’t need to manage any product keys at all. Users with Explorer or Viewer roles cannot use this feature. If you’re using Role Based Subscriptions with Tableau Server or Tableau Online, you can simplify your license management using login-based license management to eliminate separate Tableau Desktop and Tableau Prep Builder product keys. Login-based license management, helps you manage licensing for users with Creator roles on Tableau Server and Tableau Online.
