Automatic and timed login allows a user session to be started without any authentication. This is useful for systems where security is not required (for example personal laptops) and kiosk type systems where the user session is considered secure.

Automatic login is configured for a seat by setting the autologin-user setting to the name of the user account to automatically log into or setting autologin-guest to true to automatically log into a guest account. You can set autologin-session to set the session to override the default.

Timed login is configured by setting autologin-user-timeout to the number of seconds to wait until performing the automatic login. During this time a greeter will be displayed allowing the user to pick another account before the timer expires.

When performing an automatic login LightDM uses the lightdm-autologin PAM service.
