Ubuntu, a popular open-source operating system, is known for its robust security measures. One such measure is the use of a root password for performing administrative tasks such as installing software. However, what happens when you forget this password? This guide will walk you through the process of recovering your root password in Ubuntu.
To recover your root password in Ubuntu, open the Terminal and type "sudo passwd root". Enter a new UNIX password when prompted, and confirm it. This will set or reset your root password.
Understanding Ubuntu’s Root Password
By default, Ubuntu does not set a password for the root user. Instead, it uses a mechanism called
sudo (Super User DO) to provide administrative privileges to regular users. When installing software or performing other administrative tasks, you’re typically asked for your own user password, not a separate root password.
Recovering Your Root Password
If you’ve forgotten your root password or need to set one up, you can do so using the Terminal. Here’s how:
- Open Terminal. You can do this by pressing
Ctrl + Alt + Tor by searching for ‘Terminal’ in your applications menu.
- In the Terminal, type the following command:
sudo passwd root
This command uses
sudo to run the
passwd command with root privileges. The
passwd command is used to change the password of a user. In this case, we’re changing the password for the root user.
- After running the command, you’ll be prompted to enter a new UNIX password. This will be your new root password. You’ll need to enter it twice to confirm.
[sudo] password for user:
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
With these steps, you’ve successfully set or reset your root password.
Using Root Privileges
Now that you’ve set your root password, you can use it to perform administrative tasks. However, it’s important to note that logging in as the root user is not typically recommended. Most tasks can be performed using
gksudo, which temporarily elevate your privileges for a single command or action.
sudo, simply prefix your command with
sudo and then enter your own password when prompted. For example, to install a software package, you might use:
sudo apt-get install package-name
Disabling the Root Account
If you want to disable the root account for security reasons, you can do so with the following command:
sudo passwd -dl root
-dl option disables the password login for the root account, effectively disabling the account itself.
Recovering your root password in Ubuntu is a straightforward process, but it’s important to remember that using the root account should be done with caution. For most tasks, using
gksudo is a safer and more secure option. Always remember to protect your passwords and use them responsibly.

The root password in Ubuntu is used to perform administrative tasks and gain superuser privileges. It allows users to make system-wide changes and install software.
Yes, you can recover your root password by following the steps mentioned in the guide above. Using the Terminal, you can set a new root password.
Logging in as the root user can be risky as it grants full access and control over the system. It is recommended to use
gksudo for specific tasks, as it provides temporary elevated privileges and adds an extra layer of security.
Yes, you can disable the root account by using the command
sudo passwd -dl root. This disables the password login for the root account, effectively making it inactive.
If you encounter any issues during the password recovery process, you can refer to the official Ubuntu documentation for further assistance. They provide comprehensive guides and troubleshooting steps for various scenarios.
