Step 4. Share data with Customer

ThingsBoard supports multi-tenancy, allowing you to securely share devices and dashboards with different customers while keeping their data fully isolated.

Customer in ThingsBoard is a logical container used to isolate data and provide controlled access for external users under a tenant.

In this step, you will:

• create a Customer;
• assign a device and dashboard to the Customer;

This demonstrates how ThingsBoard ensures secure data isolation between customers.
