How to Create a Sudo User on Fedora

Sudo allows us to provide superuser privileges to a normal user with restrictions. It allows users to run programs with the privileges of other users. One can configure sudo to give root privileges to specific commands only.

This tutorial helps you to create a new user with Sudo privileges, allow sudo access to the existing accounts or remove sudo privileges from any account.

Create User with Sudo Access

The adduser is the default system command to create new users on your Fedora system. In Fedora systems, a default group is created with the name “wheel” having sudo privileges. So we can assign sudo privileges to any user by adding them to the wheel group.

Let’s create a new user “tecadmin” and also add them to a group “wheel”.

sudo adduser -G wheel tecadmin 

Make sure to use -G in the capital, which is used for supplementary groups of the new account.

Next, set a strong password for the new account.

sudo passwd tecadmin 

Assign Sudo Privileges to User

Use the usermod command for making changes in the existing accounts. In this case, a user tecadmin already created on your system. Now add this user to a secondary group wheel. That will provide sudo privileges to your existing account.

To add user to wheel group, type:

sudo usermod -a -G wheel tecadmin 

This will just add tecadmin user to the wheel group. One can verify the same in the /etc/group file.

Remove Sudo Privileges from User

The gpasswd is an command-line utility for managing /etc/groups and /etc/shadow. With the help of this command, you can add or remove any user from groups.

Use the following command to remote remove tecadmin account from wheel group.

sudo gpasswd -d tecadmin wheel 

We also recommend viewing the /etc/sudoers file and remove any user-specific entries.
