The <code>root</code> user is super powerful. With it, you can do anything to the system. Certainly, it is convenient to use, but it is considered bad practice because of security reasons. It could also lead to a fatal loss if you make a mistake with the <code>root</code> user. Instead, it is better to use a non-root user with <code>sudo</code> privilege to manage your system. Here is how to create one.
<ul>
<li>Create a new user, enter the password and its confirmation. If you are asked any additional information, you can fill it or just leave it.</li>
</ul>
<pre><code>adduser johndoe
</code></pre><ul>
<li>Add the created user to <code>sudo</code> group</li>
</ul>
<pre><code>usermod -aG sudo johndoe
</code></pre>Now, you can log in to the system using <code>johndoe</code> user and its password.
If you want to confirm whether the created user is in <code>sudo</code> group, use the following command:
<pre><code>groups johndoe
</code></pre>It will list the groups <code>johndoe</code> belongs to.
If necessary, you can also copy the SSH Key Authentication of the <code>root</code> user so that the created user can also log in using ssh key. To do so, use the following command:
<pre><code>rsync --archive --chown=johndoe:johndoe ~/.ssh /home/johndoe
</code></pre>Note: Above, we assume that you are logged in as the <code>root</code> user

The `root` user is super powerful. With it, you can do anything to the system. Certainly, it is convenient to use, but it is considered bad practice because of security reasons. It could also lead to a fatal loss if you make a mistake with the `root` user. Instead, it is better to use a non-root user with `sudo` privilege to manage your system. Here is how to create one.


- Create a new user, enter the password and its confirmation. If you are asked any additional information, you can fill it or just leave it.

```
adduser johndoe
``` 

- Add the created user to `sudo` group

```
usermod -aG sudo johndoe
``` 

Now, you can log in to the system using `johndoe` user and its password.

If you want to confirm whether the created user is in `sudo` group, use the following command:

```
groups johndoe
``` 

It will list the groups `johndoe` belongs to.

If necessary, you can also copy the SSH Key Authentication of the `root` user so that the created user can also log in using ssh key. To do so, use the following command:
```
rsync --archive --chown=johndoe:johndoe ~/.ssh /home/johndoe
```

Note: Above, we assume that you are logged in as the `root` user
