In a web application, the owner is the highest-level user with complete authority over the system. The owner can manage all users, roles, and permissions, configure application-wide settings, and control resources such as projects, properties, or content created within the platform. They are responsible for delegating access by assigning roles like admin or moderator, as well as overseeing billing, subscriptions, and financial aspects of the application. As the primary accountable person, the owner ensures proper usage, security, and compliance, essentially acting as the super admin of the application.
