Users

Synnax uses role-based access control (RBAC). Each user is assigned a role that determines what resources they can view, edit, or delete.

Registering Users

Select a role during registration. The new user can then log in with the registered username and password.

Synnax provides five built-in roles that cover common access patterns. Built-in roles cannot be deleted or renamed.

Role	Description	Key Capabilities
Owner	Full control of deployment, including user registration and security	All actions on all resources; user management; security settings
Engineer	Full access to system configuration except user management	Create/edit channels, projects, schematics, line plots, tasks, devices, ranges, tables, Arc code; view users and roles
Operator	View projects and visualizations; control hardware and data acquisition	Control hardware tasks; edit ranges and framers; view all resources; cannot modify system configuration
Host	For machines running the Synnax driver	Manage devices, tasks, and Arc automations
Viewer	Read-only access to all resources	View all resources; no edit or delete capabilities

Right-click the user in the Users Toolbar and select Change role. In the dialog, select a role and click Assign.

You can also drag a user onto a role in the resource tree.

Root users cannot have their roles changed, and users cannot change their own roles.
