Continue reading the guide below to learn different methods to change user password Linux and common errors that can occur during the process.
Keeping your Linux system secure is crucial, and managing passwords effectively is a big part of that. If you need to change your password, reset a forgotten password, or update a root password, there are straightforward methods to help you. In this post, I’ll guide you through various ways to manage passwords in Linux, ensuring your system stays secure. You’ll learn how to change user passwords using different commands, force password resets, and follow best practices to maintain robust security. Let’s dive in and get your system secure!
Importance of Regularly Updating Passwords
Regularly updating passwords is a key practice for maintaining robust security in any system. Here are some of the main reasons why frequent password changes are essential:
- Prevent Unauthorized Access: Changing passwords regularly helps protect against unauthorized access. Hackers often use old passwords from previous data breaches to gain entry into systems.
- Mitigate Security Risks: Frequent updates minimize the risk of using compromised passwords, reducing the chances of security breaches.
- Protect Sensitive Data: Regular password updates help ensure that sensitive information remains secure and inaccessible to unauthorized users.
- Enhance System Security: Keeping passwords fresh strengthens the overall security of the system, making it harder for attackers to exploit vulnerabilities.
How to Change User Password Linux
To change user password Linux, open the terminal and type passwd username, replacing username with the actual username. Enter the current password if prompted, then type the new password twice to confirm. For changing another user’s password, use sudo passwd username. This method ensures secure password updates for maintaining system security.
That was the quick answer. Keep reading for the detailed steps to Linux change user password using this and three more methods.
1. Using the passwd Command
The passwd command is the most commonly used method to change user passwords in Linux. Its purpose is to provide a straightforward and efficient way to update passwords, ensuring account security and preventing unauthorized access. Follow these steps to change password in Linux:
- Open a Terminal window.
- Type the following command and press Enter:
passwd usernameReplace username with the username of the account whose password you want to change. You will be prompted to enter the current password.
- Next, enter the new password and confirm it when prompted. Note that the password characters will not be displayed as you type for security purposes. Once you’ve successfully changed the password, a confirmation message will be displayed.
2. Utilizing the chpasswd Command
The chpasswd command streamlines the process of changing passwords for multiple users simultaneously. It offers the benefit of time-saving efficiency when managing a large number of user accounts, making it ideal for system administrators or situations that require bulk password changes. Follow these steps to change password Linux:
- Access your command prompt and create a text file, such as
passwords.txt.
- Enter the username-password pairs in the following format:
username1:password1
username2:password2Replace username1, username2, and so on, with the actual usernames, and password1, password2, and so forth, with the desired passwords.
- Save the file and remember its location.
- In the Terminal, type the following command and press Enter:
sudo chpasswd < passwords.txtReplace passwords.txt with the path to the file you created.
- The
chpasswdcommand will read the file and change the passwords for the specified users accordingly.
3. Employing the usermod Command
The usermod command serves a dual purpose, allowing you to modify user account settings and change passwords. It’s particularly useful for system administrators who need to manage multiple aspects of user accounts efficiently. Follow these steps to usermod change password:
- Launch the Terminal window and execute the following command and press Enter:
sudo usermod --password new_password usernameReplace new_password with the desired password and username with the username of the account you want to modify.
4. GUI Method
GNOME offers a graphical interface for changing passwords. Its purpose is to provide a user-friendly experience for those who prefer a visual approach to password management. Follow these steps to Linux set user password using GUI:
- Click on the gear icon in the top-right corner of the desktop to open System Settings.
- In the System Settings window, click on User Accounts.
- If there are multiple user accounts listed, select the account for which you want to change the password. Click on the Password field.
- Enter the current password for the user account. Enter the new password you want to set.
- Retype the new password a second time to confirm it. Finally, click the Change button to save the new password.
How to Change Another User’s Password in Linux
Changing another user’s password is a common administrative task in Linux. This is particularly useful when a user forgets their password or if the password needs to be updated for security reasons. The sudo command allows administrators to execute commands with superuser privileges. This is essential when changing another user’s password, as it requires higher-level permissions.
- Access the terminal application on your Linux system.
- Type the following command and press Enter.
sudo -iYou will be prompted to enter your password to gain superuser access.
- Use the passwd command followed by the username. For example:
sudo passwd usernameReplace username with the actual username of the account whose password you want to change.
- You will be prompted to enter the new password twice for confirmation.
How to Change Root Password in Linux
The root account has unrestricted access to the entire system, making it crucial to maintain its security. Changing the root password periodically helps protect your system from unauthorized access. The sudo passwd root command allows you to change the root password by elevating your privileges to those of the root user.

Follow these steps to change root password:
- Open the Terminal and execute the following command:
sudo passwd rootYou will be prompted to enter your current user password to verify your identity.
- Enter the new password for the root account and confirm it.
How to Force a Password Reset
Forcing a password reset can be necessary for maintaining security, especially if there has been a potential security breach or if you need to enforce a password change policy.
- Launch your Terminal window and use the following command followed by the username.
sudo passwd --expire usernameReplace username with the actual username of the account you wish to expire the password for.
- Upon the next login, the user will be prompted to change their password.
Best Practices for Linux Password Management
Managing passwords effectively in Linux is crucial for system security. By following these best practices, you can enhance the protection of user accounts and prevent unauthorized access.
- 🔒 Use Strong, Unique Passwords: Ensure all passwords are strong and unique, combining letters, numbers, and special characters. Avoid common words and use a password manager to generate and store passwords securely.
- 🔄 Regularly Update Passwords: Change passwords periodically to minimize the risk of unauthorized access. Set a reminder to update passwords every three to six months.
- 🛠️ Enable Two-Factor Authentication: Add an extra layer of security by enabling two-factor authentication (2FA) for user accounts. This requires a second form of verification, such as a mobile app code.
- 📊 Perform Regular Security Audits: Conduct regular security audits to check for weak or compromised passwords. Use tools like John the Ripper or Hydra to identify vulnerabilities and strengthen password policies.
Linux Change Password: In a Nutshell
In this article, I have covered various methods for changing passwords in Linux, including changing other users’ passwords, forcing password resets, and updating the root password.
- Unlocking and locking user accounts. This is crucial for managing user access and maintaining security in your Linux system.
- Checking Linux login history. This helps you monitor user activity, detect unauthorized access, and maintain security compliance.
- Adding root permissions to a user. This allows you to grant administrative rights to users who need elevated privileges, enhancing their ability to manage the system effectively.
