Hello charbeltarabay, Thank you for posting in GoDaddy community. Intermediate certificates are used as a stand-in for our root certificate. We use intermediate certificates as a proxy because we must keep our root certificate behind numerous layers of security, ensuring its keys are absolutely inaccessible.
Installing Intermediate Certificates
After your SSL certificate is issued, you will receive an email with a link to download your signed certificate and our intermediate certificates.
How you install the certificates depends on the server software you use. In most cases, you can download and install an intermediate certificate bundle. However, for some server types you must download and install the two intermediate certificates individually. Please refer to theInstall SSL certificatesfor the specific process you should follow.
