Debian is a multi-user operating system, as well as all other Linux distributions. For numerous command-line and GUI apps, each user might have varying permission levels and particular settings.

One of the fundamental abilities a Linux user should have is, the ability to add and remove users.

This tutorial describes how to add and remove users on Debian 9. We will also address a few FAQs on how to add and remove users on Debian 9.


To add and delete users on your Debian system, you must be logged in as root or as a user with sudo access.

How To Add User on Debian

To create a new user account on Debian, you can use the useradd and adduser command-line programs.

adduser is a nice interactive frontend to useradd written in Perl. useradd is a low-level program for adding users.

To use the adduser command to create a new user account named username, type:

sudo adduser username

Adding user `username' ...
Adding new group `username' (1001) ...
Adding new user `username' (1001) with group `username' ...
Creating home directory `/home/username' ...
Copying files from `/etc/skel' ...

A series of questions will be asked from you. All other fields are optional, except for the password.


Enter new UNIX password: 
Retype new UNIX password: 
passwd: password updated successfully
Changing the user information for username
Enter the new value, or press ENTER for the default
	Full Name []: 
	Room Number []: 
	Work Phone []: 
	Home Phone []: 
	Other []: 
Is the information correct? [Y/n] 

You must enter Y to confirm that the information is correct on the final prompt.

The command will create the new user's home directory and copy files from the /etc/skel directory into it. The user can write, edit, and delete files and folders in their home directory.

Sudo access is allowed to members of the sudo group by default on Debian.

Add the newly formed user to the sudo group if you want the user to have administrative rights:

sudo usermod -aG sudo username

How To Delete a User on Debian

If you no longer require the user account, you can delete it using userdel or deluser. On Debian, the deluser command is preferred over the low-level userdel command because it is more user-friendly.

Run the following command to deactivate the user without deleting the user's files:

sudo deluser username

Use the --remove-home flag to delete the user, as well as its home directory and mail spool. And to use that, you have to install the following package:

sudo apt-get install perl-modules
sudo deluser --remove-home username

FAQs to Add and Delete Users on Debian 9

How can I grant root privileges to a user on Debian 9? 

To grant root privileges to a user, add the user to the sudo group: sudo adduser username sudo. This allows the user to use the sudo command for administrative tasks.

What is the command to delete a user on Debian 9? 

To delete a user from Debian 9, use the deluser command followed by the username: sudo deluser username. Be careful as this action is irreversible.

Can I specify additional user details during user creation? 

Yes, you can provide additional user details during user creation using the adduser command with options. For example, sudo adduser --gecos "John Doe,,,Mobile" username allows you to specify full name, room number, work phone, and home phone.
