# Companies and Users
This article explains the concepts of company and user on the WebAccess/DMP (WADMP) platform. We will explain the differences between signing up to WADMP and having an account created for you by an administrator. We will also explain the concept of parent and child companies.
There are two ways to become a user of WADMP:
- Signup at WADMP (opens new window) by creating an account.
- The company administrator creates an account for you.
In both cases, the user will receive an email from the platform to confirm their email address. Then, using the 1st option, the user is the administrator for their company with the following permissions.
As you can see, you have permission to view, add, edit, and delete every entity on the system.
Using the 2nd option, the permissions are set by the company administrator.
A user may be a member of one or more companies. Therefore, the user permissions may be different for each company. For example, a user may have to create and view user permissions on "Company A" but only view user permission on "Company B".
Note: You cannot assign permission that you do not have yourself.
When you log in to WADMP, you can manage devices and users for all companies you belong to and have permission to do so.
Click on a company to filter devices belonging to that company.
The company can only exist with at least one Company admin. When registering on WADMP for the first time, you will be asked to enter your company details. You are automatically the administrator for this company. You may also be added to an existing company by that company's administrator.
Once you have signed up to WADMP, you can create users and add them to companies with a set of permissions. You may also create other companies and assign users to those companies.
You can create a maximum of three root companies. Parent companies may have many child-companies. Child-companies may also have child-companies. There are no restrictions on the number of levels of child-companies you can create.
Example of Company hierarchy:
|Root and Parent
|Parent and Child
Having created your companies, you can now begin to manage and monitor devices. To control a device, you must first claim it to your company. See Claim my device (opens new window)
Having claimed your device, you can now configure and monitor it.
# System Administrator
The System Administrator is the administrator of the platform. In addition to the standard permissions, the Sysadmin can also Register and Delete devices and claim devices to any company.
Contact your Sysadmin if you have any issues that your company administrator cannot resolve.
