Configuring Kali Linux to log in automatically as the kali user upon booting up can streamline the login process, especially for personal or non-sensitive environments. However, keep in mind that automatic login bypasses the authentication step, which can pose security risks if not applied cautiously. Here’s a comprehensive guide on how to set up automatic login for the kali user in Kali Linux:

Automatic Login Setup in Kali Linux:

Configure the LightDM display manager manually to allow auto login:

• Open a terminal window. Check if you have lightdm already installed by running the below command: cat /etc/X11/default-display-manager. This will show you the default display manager. If you do not see lightdm in the output install the lightdm GTK as given below.
• Install the LightDM GTK+ Greeter Settings tool:

1
2

sudo apt update
sudo apt install lightdm-gtk-greeter-settings

• After it is installed, enable automatic login is by configuring the lightdm.conf file manually:

1. Open the lightdm.conf file for editing:

   1	sudo nano /etc/lightdm/lightdm.conf

2. In the lightdm.con file, under [Seat:*] section you will see autologin-user and autologin-user-timeout values. If you do not find them, add the following lines at the end of the file:

   1 2 3

   [SeatDefaults] autologin-user=kali autologin-user-timeout=0

   Ensure that kali represents the actual username.

3. Save the changes and exit the text editor.

Final Notes:

Automatic login can be a convenient feature, especially in single-user environments or for non-sensitive systems. However, always assess the potential security risks before implementing it. It’s crucial to balance convenience with security to ensure the safety of your system and data.
