How to add users and groups in Linux

For Linux administrators, managing user and groups is a fundamental aspect of Linux system administration as it allows one to control access to files, directories, and system resources. This process is crucial for security and productivity. As a rule, for the system administrator, it is recommended to create an administrator account and a separate user account for daily use.

Each user has a unique account, typically assigned a User ID (UID), which determines their permissions. Groups allow multiple users to share permissions for files and system resources. These commands provide a solid foundation for managing users and groups in Linux.

Users and Groups via Graphical Interface

The Linux command line might be daunting for beginners. Luckily, Linux desktop environments do offer a graphical user interface (GUI). Proceed to open Settings via the Apps and proceed to type users in the search bar. Click on Users to proceed forward. Click Unlock and type in the admin password. Then, click on Add User. For security reasons, be suer that Automatic Login is turned off.

The new user account default is standard user. Only create an administrator account when deemed appropriate. It is good practice to use a standard account for daily usages and one administrator account when elevated privileges are required.
