Disabling direct root login over SSH is an important security practice for any cPanel server. Allowing remote root access increases the risk of brute-force attacks and unauthorized logins. By disabling root login, administrators must first log in using a normal user account and then switch to root privileges securely. This approach also allows administrators to access WHM/cPanel without the root password, improving security while maintaining full administrative control over the server. This guide explains how to disable root SSH login on a cPanel server safely without locking yourself out. Why Disable Root SSH Login? The root user has complete control over the server. If attackers gain root access, the entire system can be compromised. Security benefits include: Important Step Before …
