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 user, also known as the superuser, possesses complete administrative control over your Ubuntu system. This means you can execute any command and modify any file without prefixing commands with `sudo`.
Ubuntu 24.04, like other distributions, disables direct root login by default. This security measure encourages the use of `sudo` for individual administrative commands.
However, if you require direct root access for specific tasks or workflows, you can enable it with a few straightforward commands.
Set a password for the root account using `sudo passwd root`. Then, switch to the root user with `su -`. This grants full administrative privileges to your Ubuntu system.
Enable root
You can enable the root user on Ubuntu 24.04 by first using a sudo command to switch to the root user.
Go ahead and run this `sudo` command.
sudo -s
You’ll be prompted for your password, so type that in.
Next, run the command to set the root user’s 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’ll know it’s the root user when the prompt begins with root and ends with #.
root@Ubuntu:~#
Restrict the su command
After enabling the root account, it’s smart to limit who can use the ‘su’ command to switch to other 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!
