The Plesk admin area is secured by an SSL based connection (HTTPS) and out of the box uses a self-signed certificate. This will generate a warning in most browsers, stating that the certificate can't be verified. While this doesn't present a security risk, it can be disconcerting to some clients.

You can purchase an SSL certificate for your plesk domain (eg admin.yourdomainname.com.au) or use the latest Plesk Let's Encrypt extension to secure it for free.
