Add, Delete And Grant Sudo Privileges To Users In Fedora 36
======
Create sudo user in Fedora

Using `sudo` program, we can elevate the ability of a normal user to run administrative tasks, without giving away the `root` user's password in Linux operating systems. This guide explains how to add, delete and grant sudo privileges to users in Fedora 36 desktop and server editions.

I've divided this guide in three sections. The first section teaches you how to create a new user. In the second section, you'll learn how to give sudo access to the existing user. And in the last section, you will know how to remove sudo access from a user. I've also provided example commands in each section, so you can understand it better.

First, we will start with giving sudo access to a new user.

### 1. Create A New User In Fedora

Login to your Fedora system as `root` user or `sudo` user.

We can use either `useradd` or `adduser` commands to create users in Linux.

For the purpose of this guide, I am going to create a new user called **"senthil"** using `adduser` command.

To do so, I run the following command with `sudo` or `root` privilege:

```
$ sudo adduser senthil
```

Next, I am going to set a password to the newly created user "senthil" with `passwd` command:

```
$ sudo passwd senthil
```

![Create A New User In Fedora][1]

We just created a normal user called "senthil". This user has not been given sudo access yet. So he can't perform any administrative tasks.

You can verify if an user has sudo access or not like below.

```
$ sudo -l -U senthil
```

**Sample output:**

```
User senthil is not allowed to run sudo on fedora.
```

![Check If An User Has Sudo Access][2]

As you can see, the user "senthil" is not yet allowed to run sudo. Let us go ahead and give him sudo access in the following steps.

### 2. Grant Sudo Privileges To Users In Fedora

To add a normal user to **sudoers** group, simply add him/her to the `wheel` group.

For those wondering, the `wheel` is a special group in some Unix-like operating systems (E.g. RHEL based systems). All the members of `wheel` group are allowed to perform administrative tasks. Wheel group is similar to `sudo` group in Debian-based systems.

We can add users to sudoers list in two ways. The first method is by using `chmod` command.

#### 2.1. Add Users To Sudoers Using Usermod Command

```
Usermod
```

To grant sudo privileges to a user called "senthil", just add him to the `wheel` group using `usermod` command as shown below:

```
$ sudo usermod -aG wheel senthil
```

Here, `-aG` refers append to a supplementary group. In our case, it is `wheel` group.

Verify if the user is in the sudoers list with command:

```
$ sudo -l -U senthil
```

If you output something like below, it means the user has been given sudo access and he can able to perform all administrative tasks.

```
Matching Defaults entries for senthil on fedora:
    !visiblepw, always_set_home, match_group_by_gid, always_query_group_plugin,
    env_reset, env_keep="COLORS DISPLAY HOSTNAME HISTSIZE KDEDIR LS_COLORS",
    env_keep+="MAIL QTDIR USERNAME LANG LC_ADDRESS LC_CTYPE",
    env_keep+="LC_COLLATE LC_IDENTIFICATION LC_MEASUREMENT LC_MESSAGES",
    env_keep+="LC_MONETARY LC_NAME LC_NUMERIC LC_PAPER LC_TELEPHONE",
    env_keep+="LC_TIME LC_ALL LANGUAGE LINGUAS _XKB_CHARSET XAUTHORITY",
    secure_path=/usr/local/sbin\:/usr/local/bin\:/usr/sbin\:/usr/bin\:/sbin\:/bin\:/var/lib/snapd/snap/bin

User senthil may run the following commands on fedora:
    (ALL) ALL
```

![Add A User To Sudoers Group Using Usermod Command][3]

As you see in the above output, the user "Senthil" can run ALL commands on any host.

#### 2.2. Add Users To Sudoers By Editing Sudoers Configuration File

The another way to add users to sudoers list is by directly adding him/her to the sudoers configuration file.

Edit sudoers configuration file using command:

```
$ sudo visudo
```

This will open `/etc/sudoers` file in your **Vi** editor or whatever you have in your `$PATH`. Scroll down until you find following entry:

```
root    ALL=(ALL)       ALL
```

Right after the above entry, add the following line:

```
senthil ALL=(ALL)       ALL
```

![Add Users To Sudoers Group By Editing Sudoers Configuration File][4]

Here, the line `ALL=(ALL) ALL` refers the user "senthil" can perform any commands on any host. Replace "senthil" with your own username. Save the file and close it.

That's it. The user has been granted sudo access.

#### 2.3. Verify Sudo Users

Log out from the current session and log back in as the newly created sudo user. Alternatively, you can directly switch to the other user, without having to log out from the current session, using the following command:

```
$ sudo -i -u senthil
```

![Switch To New User In Fedora Linux][5]

Now, verify if the user can able to perform any administrative task with `sudo` permission:

```
$ sudo dnf --refresh update
```

![Run Dnf Update Command With Sudo][6]

Great! The user can able to run the `dnf update` command with sudo privilege. From now on, the user can perform all commands prefixed with sudo.

### 3. Delete Sudo Access From A User

Make sure you logged out of the user's session and log back in as `root` or some other sudo user. Because you can't delete the sudo access of the currently logged in user.

We can remove sudo privileges from an user without having to entirely delete the user account.

To do so, use `gpasswd` command to revoke sudo permissions from a user:

```
$ sudo gpasswd -d senthil wheel
```

**Sample output:**

```
Removing user senthil from group wheel
```

This will only remove sudo privilege of the given user. The user still exists in the system

Verify if the sudo access has been removed using command:

```
$ sudo -l -U senthil
User senthil is not allowed to run sudo on fedora35.
```

![Delete Sudo Access From A User Using Gpasswd Command][7]

#### 3.1. Permanently Delete User

If you don't need the user any more, you can permanently remove the user from the system using `userdel` command like below.

```
$ sudo userdel -r senthil
```

The above command will delete the user "senthil" along with his  `home` directory and mail spool.

### Conclusion

This concludes how to add, delete and grant sudo privileges to users in Fedora 36 operating system. This method is same for other RPM-based systems as well.
