Secure Shel allows you to manage your network service to control any unsafe situation. In Linux and Unix as operating systems, the root user acts as a superuser who can do many things that an ordinary user cannot. To connect to your system remotely and perform administrative tasks, you must log in as root. In this article, you will learn how to enable root login via SSH in Debian 10.

Linux does not allow logging into the server as root via SSH protocol and has been disabled from the main ssh configuration file by default. Therefore, you receive an error message (due to security reasons) while trying to log in as root. The error message is “Permission denied, please try again.” Join us with this article to review the process of enabling root login via ssh.
Log in as
When you log in with the root account, you are a special user with administrative rights. However, you need to be sure of your knowledge about the commands you execute, as any sloppy or malformed command will render the entire operating system unusable. That’s why security reasons don’t allow you to log in as root and you have to enable it. In Debian, it is originally enabled as a security precaution, which means that you cannot log in directly as root via SSH.
Allow SSH root login in Debian
Because the PermitRootLogin parameter controls the ssh root permission, you must change its values. The parameter is /etc/ssh/sshd_config and the value of PermitRootLogin is “without-password”. Therefore, it must be PermitRootLogin to Yes to allow root login.

Then, find PermitRootLogin and change its value to “Yes”. If the line exists and is commented with a “#”, delete the “#”.
Now, you can save the updated /etc/ssh/sshd_config file and restart the SSH server. Use the following command to do this:
systemctl reboot sshd
i.e. if you don’t see any new errors, you should be able to access your Debian server using the root user account via SSH protocol
In this article, you learned how to enable root login via SSH in Debian 10. As you know, by default SSH root login is disabled in Debian as it does not recommend using root password via ssh.
