Operating System and Software Versions
- Operating System: – Ubuntu 18.04 Bionic Beaver Linux
Privileged access to your Ubuntu System as root or via
sudo command is required.

Change password using Command Line
In the first example we will be changing password for the currently logged in user
linuxconfig using the
passwd command. No special privileges are required.
passwd command with no additional options or arguments will change the password for the current logged in user. Open up terminal and enter:
Please note that you will be prompted to enter your current password first after which you will be required to enter and retype your new password. You will not be able to see the password you are typing on the terminal. However, the terminal is reading your keyboard input regardless, so just keep typing.
Using the next example we will change the password for a different user called
john. In this case we need to use the
sudo command and specify the user’s name for whom we wish to change the password:
$ sudo passwd john
After executing the above
passwd command you will be first asked to enter your current administrative sudo password, followed by the new user password.
