Preparing to Create a User Account
Before creating a new user account on Linux, it’s essential to ensure that you have root access to the system. Root access is necessary to perform administrative tasks, such as creating and managing user accounts. If you don’t have root access, you’ll need to contact your system administrator to obtain the necessary permissions.
Once you have root access, you can begin the process of creating a new user account. However, before doing so, it’s crucial to understand the different types of user accounts available on Linux. There are two main types of user accounts on Linux: system accounts and user accounts.
System Accounts
System accounts are used by the operating system to perform specific tasks, such as running system services or executing system scripts. These accounts are typically created during the installation of the operating system and are managed by the system administrator. System accounts are not intended for individual users and should not be used for regular user activities.
User Accounts
User accounts are created for individual users who need to access the system. These accounts can be assigned different levels of access and permissions depending on the user’s role and responsibilities. User accounts are intended for regular user activities and should not be used for system-level tasks.
Before creating a new user account, it’s important to determine the user’s role and responsibilities to assign the appropriate level of access and permissions. This will help ensure that the user can perform their tasks without compromising the security of the system.
Creating a New User Account on Linux
Creating a new user account on Linux is a simple process that can be done using the command line interface. Here are the steps to follow:
Step 1: Open the Terminal

on your keyboard, or search for “Terminal” in the applications menu.
Step 2: Log in as Root
Before you can create a new user account, you need to log in as root. To do so, type the following command in the terminal and press Enter:
sudo su
You will be prompted to enter your password. Once you have entered your password, you will be logged in as root.
Step 3: Create a New User Account
To create a new user account, type the following command in the terminal and press Enter:
adduser username
Replace “username” with the desired username for the new user account. You will be prompted to enter a password for the new user account. Make sure to choose a strong and secure password that meets the system’s password policy requirements.
Step 4: Assign Permissions to the New User Account
Once you have created the new user account, you need to assign permissions to the account. To do so, type the following command in the terminal and press Enter:
usermod -aG sudo username
Replace “username” with the username of the new user account. This command adds the new user account to the “sudo” group, which allows the user to perform administrative tasks.
Step 5: Test the New User Account
To test the new user account, log out of the root account by typing the following command in the terminal and pressing Enter:
exit
Then, log in to the new user account by typing the following command in the terminal and pressing Enter:
su - username
Replace “username” with the username of the new user account. You will be prompted to enter the password for the new user account. Once you have entered the password, you will be logged in to the new user account.
It’s important to note that creating a new user account on Linux is just the first step in managing user accounts on your system. Be sure to assign appropriate permissions and groups to the new user account to ensure that they have access to the resources they need.
Managing user accounts on Linux
Understanding how to manage user accounts effectively is crucial after creating a new user account on Linux. This section will offer advice on how to modify or delete an existing user account as well as best practices for managing user accounts on Linux.
Modifying or Deleting an Existing User Account
Use the usermod
command to modify an existing user account. You can modify the password, home directory, and other settings for an existing user account using this command. Use the following command, for instance, to change the home directory of a user account:
Usermod -d /new/home/ directory username
Use the command “userdel” to delete an existing user account. The user account and all associated files and directories are taken out by this command. Use the following command, for instance, to delete the user account “jdoe”:
Userdel jdoe.
How to manage user accounts on Linux: Best Practices
To ensure the system’s security and stability when managing user accounts on Linux, it is crucial to abide by best practices. These pointers will help you manage user accounts on Linux:
- For all user accounts, use solid and secure passwords. Use common words or phrases instead, and think about creating and storing complex passwords with a password manager.
- Based on the user’s duties and role, assign access levels and permissions. Only those who need it have access to sensitive files and directories.
- To make sure that user accounts are still required and suitable, regularly review and update them. To lower the likelihood of unauthorized access, clear out any unused or active accounts.
- To spot and stop unauthorized access or malicious activity, keep an eye on user behavior. Utilize tools like auditd to keep track of user activity and spot potential security risks.
