This article describes how to automatically log in to a virtual console at the end of the boot process. This article only covers console log-ins; see Start X at Login for information about automatic login into Xorg.

Configuration

Configuration relies on systemd drop-in files to override the default parameters passed to agetty.

The configuration differs for virtual and serial consoles. In most cases you would want to setup up automatic login on virtual console, the one which device name is ttyN, where N is a number. The configuration of the automatic login for the serial consoles will be slightly different. Device names of the serial consoles look like ttySN, where N is a number.

Virtual console

Create the following file (and the leading directories):

/etc/systemd/system/getty@tty1.service.d/autologin.conf
[Service]
ExecStart=
ExecStart=-/usr/bin/agetty --autologin username --noclear %I 38400 linux
Tip: The option Type=idle will delay the service startup until all jobs (state change requests to units) are completed. When using Type=simple, the service will be started automatically, but boot-up messages may pollute the login prompt. This option is particularly useful when starting X automatically. To use this option, add Type=simple into autologin.conf.

If you want to use other tty than tty1 see Systemd FAQ.

Serial console

Create the following file (and the leading directories):

/etc/systemd/system/serial-getty@ttyS0.service.d/autologin.conf
[Service]
ExecStart=
ExecStart=-/sbin/agetty --autologin username -s %I 115200,38400,9600 vt102
