When you in WHM, you can set it so you can make a SSH Key instead of using a password.
I would love to be able to login to WHM with the username root and the key which I use for SSH, therefore its secure. But allow Resellers to be able to access WHM via their cPanel the normal way via the logo.
However be able to turn it off via their reseller WHM, and set them a Key up. It means only people who are allowed to log into WHM can and stop hackers.
Its my opinion when running a hosting business.
