Unity Organizations allow you to organize your game development projects, teams, and services. An Organization can consist of a single user, or multiple users collaborating across one or more projects.
You can create or belong to as many Organizations as you like. To keep your activities for different companies or personal use separate, Unity recommends using a separate Organization for each entity. Separating your activities through Organizations also facilitates seamless personnel changes. For example, if an employee leaves your company, you can reallocate their seat because the subscription is tied to the Organization instead of the user.
To view a list of Organizations associated with your Unity ID, sign in to the Unity ID portal and select Organizations from the left navigation bar.
