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.

Configuration differs for virtual versus serial consoles. In most cases you want to setup up automatic login on a virtual console, (whose device name is ttyN, where N is a number). The configuration of automatic login for 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 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 immediately, 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
