To set up an additional user with root privileges for handling WHM as a Reseller, follow these steps:
1. Log in to your server via SSH and execute the following commands:
useradd secondroot
passwd secondroot
usermod -aG wheel secondroot
echo "secondroot:all" >> /var/cpanel/resellers
Note: Replace "secondroot" with your desired username.
2. Log in to WHM with your root credentials and perform these steps:
Navigate to "Home".
Click on "Resellers".

- Select "Edit Reseller Nameservers and Privileges".

In the "Edit Reseller Nameservers and Privileges" section, ensure the new user’s ACL settings match those of the root user.

3. Save your changes.
Now you can log in to WHM using the new user account.
