How To Create A Root Password In Ubuntu

Introduction

Are you looking to change the root password in Ubuntu?

Changing passwords is a good practice and should be done periodically.

Linux allows multiple user accounts, each having its own password. Users can only change their own password. However, there is always a sudo/root (SuperUser) account. Root users can change the password of any account, including their own. By default, the root user is locked.

There are three (3) ways to change passwords in Ubuntu.

The first two (2) options use the command line, and the other uses Linux's graphical interface (GUI).

Option 2: Change sudo Password with the passwd Command

An alternative is to switch to the root user and then run the passwd command to change the root password.

1. First, open the terminal (CTRL+ALT+T).

2. Switch to the root user with the command:

          sudo –i

Type in your current password and hit Enter. The output you receive should show that you can now run commands as root.

3. Next, change the password by running the command:

          passwd

Type and retype a new password to verify the change.

4. After changing the password, log out of the root user with the command:

          exit

5. Exit out of the terminal with the same command:

          exit

Option 3: Changing Ubuntu Password Using GUI

To change the default root password in Ubuntu without using the terminal or any commands, use the graphical interface.

1. Open the Activities overview by pressing the Windows or Super key.

2. Type settings in the search bar and click on the Settings icon.

3. In Settings, click on the Details card (which is most likely the last one).
