How to configure automatic login in KDE

You normally authenticate via username and password combination to access your Linux system. Whether it's a necessity or simply for convenience, you can configure your KDE-based Linux system to log you in during system boot automatically. It could be the case if you're running a dedicated or single-user system.

This is possible if you're using SDDM as your login manager. SDDM is the default login manager in Kubuntu or most other KDE-based Linux distributions.

1. Launch System Settings from the Application Launcher.
2. Go to Startup and Shutdown from the sidebar menu.
3. Click on the Behavior button from the Login Screen panel.
4. Click on the Automatically log in check box to enable automatic login.

   Make sure this check box is not ticked to disable automatic login.

5. Select a user from the list to enable automatic login and the corresponding session type.
6. Click Apply to save the configuration.
7. Enter your password if requested and click on the OK button.

   Your user need to have administrator privilege.
