It’s commonly used by system administrators to manage user accounts efficiently and securely.

Learn To Configure Linux Users’ Passwords with chpasswd Command

Once you are done, press ctrl+d to complete your task.

Also, you can use the -c option to change your encryption method. By default, chpasswd uses the PAM method. For example, to change it to None, you can run:

chpasswd -c NONE

Step 3 – Update Users’ Passwords via chpasswd Password File

Another method to update and configure Linux Users’ Passwords with chpasswd Command is to use a file with the current users and their updated passwords.

First, you need to create a file with your desired text editor like Vi editor or Nano editor:

vi mypasswords.txt

At the file, you must add the users with the new passwords in Linux servers as shown below:


When you are done, save and close the file.

Then, you can verify the password file content with the command below:

cat mypasswords.txt

At this point, you must run the chpasswd command in Linux to redirect data from the mypasswords.txt file:

chpasswd < mypasswords.txt

This will read your passwords from the file.


The chpasswd command provides an efficient way to update passwords for user accounts individually or in bulk. By accepting username and password pairs from standard input or a specified file, you can easily update your users’ passwords in Linux. Hope you enjoy it.
