Having the option of logging in to your server with SSH is essential for some web administrators, but logging in your server with root credentials via SSH is always unsafe. By the word root credentials, I mean that you should not remotely login with your server with root user name, rather use a less privileged user to login to your server and then use the “su” command to login as a root user.
So, the purpose of this post is to show you:
- How to disable SSH with root username?
- How to enable a normal user to login with SSH?
- How to use root username after login with less privilege user name?
