Step 5. Create and activate a Customer User

Customer User is a user account linked to a specific customer. Customer users have read-only access and can view only the entities assigned to their customer.

In this step, you will create a Customer User account and activate it to verify secure, customer-level access to assigned devices and dashboards.

Create a user account for the Customer:

1. In the Customers list, click Manage customer users for your customer.
2. Click + Add user in the top-right corner.
3. Enter the user’s email address. Optionally, specify the first name, last name, phone number, preferred UI language, and unit system.
4. Choose the user activation method:
   • Display activation link — generates an activation link that you can copy and share manually.
   • Send activation mail — sends the activation link to the specified email address (requires a configured mail server). For this guide, select Display activation link.
5. Click Add.
6. Copy the activation link and store it securely — you will use it later to activate the new user account.
7. Click OK to finish.

A Customer User account has been created.

Use the activation link from the previous step to complete account setup and sign in as a Customer User.

1. Open the activation link in a new browser tab and press Enter.
2. Create a password by entering it twice, then click Create password.

After activation, you will be logged in to the ThingsBoard user interface.

As a Customer User, you can:

• view assigned devices and their telemetry data on dashboards;
• monitor alarms related to assigned devices;
• acknowledge and clear alarms.
