NOTE: This guide is for giving SSH access to individual cPanel accounts on a VPS or Blaze. If you're on a Personal, Business or Reseller plan, log in to https://control.crucial.com.au/clientarea.php and submit a support ticket requesting SSH access.
Accessing SSH from an individual cPanel account is far safer than using the root login as a cPanel user is limited to accessing and editing files on that specific account. It's useful for a developer who wants to use tools like Git or Composer to build a website.
Step 1 - Log in to WHM and click on List Accounts
Step 2 - Click on the + next to the domain and click Modify Account
NOTE: Here you can see the Username and IP Address to use to log into SSH. You can also change the password which is the same for SSH, cPanel and FTP.
Step 3 - (1) Tick Shell Access then (2) Click Save
