How to add your SSH key on a dedicated server?Every SiteGround customer using a dedicated server has root SSH access to the server.
If you have a dedicated server with us and you wish to be able to connect via SSH to it, you should first generate an SSH key pair for it. More information on how to do this is available in the following articles:

How to generate an SSH key in Linux
Once you have generated your public and private SSH keys, you should add the public key through your WHM.
To do so, log in to your server's WHM panel as root and go to Manage SSH Keys located in the Security section. Click the Import Key button. Type in a name and a passphrase for the key and paste your public key in the corresponding field. You don't have to paste your private key. Click Import to import your key.
