How to Enable Root User on Ubuntu 24.04
You enable the root user on Ubuntu 24.04 by setting a password for the root account.
The root account, often called the superuser, holds unrestricted administrative privileges on your Ubuntu system. It allows you to execute any command, modify any file, and manage all aspects of your operating system without needing to preface commands with ‘sudo’.
By default, this powerful account is disabled on Ubuntu distributions like 24.04 because its password isn’t initially set. This is a security measure, promoting the use of ‘sudo’ for administrative tasks.
However, if you prefer direct root access for convenience or specific workflows, enabling it is straightforward. Follow these steps to regain full superuser control.
Enable root
The user account added during installation is set an administrative account that can use the sudo command. It’s easy to use this account to enable the root user account.
To enable the root account, run this sudo command.
sudo -s
Type your password when prompted.
Then, run the command to set the root user password.
sudo passwd root
When prompted, enter and confirm a new password for the root account.
New password:
Retype new password:
passwd: password updated successfully
With the root user password set, the account is automatically enabled.
Run the command below and type the root password to switch to the root user.
su -
You will know it’s the root user when the prompt begins with root and ends with #.
root@Ubuntu:~#
Restrict the su command
When you enable the root account, you should also restrict who can use the [su] command to switch users including root.
To do that, run the command below to open the su config file.
nano /etc/pam.d/su
Uncomment the highlighted line in the file.
# Uncomment this to force users to be a member of group adm
# before they can use `su'.
auth required pam_wheel.so group=adm
Exit and save.
Then, add the user who should be allowed to use the su command to the [adm] group.
usermod -aG adm richard
That should do it!
