In this article, we will see how to disable SSH root login to your server.

This is an open opportunity for hackers as they can brute force your root password and potentially get access to your server if the password can be guessed. That’s the reason the SSH login needs to be disabled.

1) Login to the server through SSH.
2) Open the file “/etc/ssh/sshd_config” (SSH configuration file) in any of the text editor using the command :

4) Save and close the file. Restart the SSH and save the changes by executing any one of the commands below :
systemctl restart sshd
service sshd restart
Now onwards, any attempt to SSH to the server with the root account will automatically be denied.
Now, you will not be able to SSH to the server with the root account.
