A master reseller can create normal resellers and cPanel accounts, so they can run a reseller hosting business of their own. You create them in WHMReseller like a normal reseller, with two extra limits: how many resellers they can create and how much they can share out.
Before you start
- Your MdmHost plan must allow master reseller creation. Alpha level is needed on some setups; check the WHMReseller dashboard.
- The domain, username, password and email for the new master reseller.
- Your plan for their limits: total disk and bandwidth, max cPanel accounts and max resellers.
Note: WHMReseller menu names change slightly between versions. If a label in this guide differs from your screen, look for the closest match in the WHMReseller menu.
Create the master reseller
- Open WHM → Plugins → WHMReseller.
- Click Create Reseller and fill in domain, username, password, email and package as in creating a reseller.
- Set Reseller type to Master Reseller.
- Set Max resellers: how many resellers they can create.
- Set Max accounts: total cPanel accounts for them and everyone below them.
- Set Disk space and Bandwidth for their whole tree.
- Choose privileges, including access to WHMReseller itself.
- Click Create.
How limits flow down
Limits are a tree. If you give a master reseller 100 GB and 100 accounts, everything they give their resellers is taken from those 100 GB and 100 accounts. They cannot give out more than they have, unless you allow overselling.
| Level | Example disk | Example accounts |
|---|---|---|
| You (VIP plan) | Your plan allocation | Your plan allocation |
| Master reseller | 100 GB | 100 |
| Their reseller A | 40 GB | 30 |
| Their reseller B | 40 GB | 30 |
Warning: Avoid giving master resellers overselling unless you monitor them. Over-allocated trees are the most common cause of "out of space" problems on master reseller plans.
Hand over and check
- Log in as the master reseller in a private window.
- Confirm they see WHMReseller and can open Create Reseller.
- Confirm the type list only offers Reseller (they cannot create other master resellers unless you allowed it).
- Share your nameservers and branding guides, for example branding cPanel.
Troubleshooting
Master Reseller is not offered as a type
Your own level does not allow it. On MdmHost, creating master resellers may need alpha access; open a ticket to ask.
The master reseller can create more than you expected
Check whether overselling or unlimited was ticked, then edit limits in managing reseller limits.
Frequently asked questions
What is the difference between master and alpha resellers?
A master reseller creates resellers. An alpha reseller can additionally create master resellers. See the alpha reseller guide for details.
Can a master reseller brand WHM for their resellers?
They can brand cPanel for their own accounts. Their resellers set their own branding in WHM Customization.
Who supports the master reseller's customers?
You do, or the master reseller does, depending on your agreement. MdmHost supports you as the plan owner.
How should I secure a master reseller login?
Use a long random password and ask the reseller to enable two-factor authentication in their cPanel under Preferences → Two-Factor Authentication. WHM uses the same login, so this protects both.
