Enable or Disable Automatic Login in Debian 11 Bullseye

To secure our system we generally use a password to login into a Linux and other OS. However, if you are the only person who has access to your Linux system such as Debian 11 Bullseye then you can enable the autologin feature and here we will know how?

Systems that are in offices or in insure locations need to be secure with a login “password”. That a user has to enter every time he or she wants to access the files and other data residing in it. Well, this happens every time we start our computer or log out. It is a good thing but if you only work with the computer alone anyway, the repeated password entry is quite annoying. If you want to boot straight through to the desktop, you can log in automatically and switch off the password prompt when the system starts. Here we will show you how to do that in Debian-based systems.

Steps to Auto login in Debian 11 Bullseye

The steps given here will be the same for other Debian-based Linux systems such as Ubuntu including Linux Mint, POP_OS, MX Linux Elementary OS, and more…

There are two ways to enable autologin on Debian 11 with LightDM or GDM3, one is using the command terminal and the other via its default Gnome graphical Desktop user interface. Here we will show you both.

#1 Using Command line

Requirements

Debian Linux
File Editor such as Nano
A non-root sudo user

Debian 11 Bullseye – Apt Update

Run the system update command and after that install the popular easy-to-use “nano” editor.

sudo apt update
sudo apt install nano

 

Edit daemon Configuration file- for GDM display

Open command terminal on your Debian 11 Linux. After that, we will edit the Daemon configuration file that holds syntax that can enable the auto-login on our Debian 11 bullseye.

sudo nano /etc/gdm3/daemon.conf

In the file, your will see a line “Enabling Automatic login” with other setting “#AutomaticLoginEnable = true” and “#AutomaticLogin = user 1″.

Just go to – AutomaticLoginEnable =true and remove the # tag and do the same for AutomcaicLogin as well. But here replace the “user 1” with your system user that you want to log in automatically with a system reboot.

Save the file by pressing Ctlr+X, hit the Enter key, and then exit the same using – Ctlr+O.

Now, whenever you start your system it will not ask for a login password.

For LightDM (optional)

If you are using the LightDM as display manager instead GDm3, then edit

sudo nano /etc/lightdm/lightdm.conf

Scroll to the end of the file, add:

autologin-user=username

Note: Replace username with the user for you want to enable the autologin.

SaveCtrl+X, type Y, and hit the Enter key.

In case, in the future, you want to disable auto-login then again edit the same daemon file. And add # in front of two values we have edited.

Once you have added the # tag save the file again using Ctrl+X, press Y, and hit the Enter key.

Whereas for LightDM, simply remove the autologin-user=your-username
