This article describes how to automatically log in to a [[Wikipedia:Virtual console|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 [[Systemd#Editing_provided_unit_files|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 {{ic|tty''N''}}, where {{ic|''N''}} is a number). The configuration of automatic login for serial consoles will be slightly different. Device names of the serial consoles look like {{ic|ttyS''N''}}, where {{ic|''N''}} is a number.
 
 
 
=== Virtual console ===
 
 
 
Create the following file (and leading directories):
 
 
 
{{hc|/etc/systemd/system/getty@tty1.service.d/autologin.conf|2=
 
[Service]
 
ExecStart=
 
ExecStart=-/usr/bin/agetty --autologin ''username'' --noclear %I 38400 linux
 
}}
 
 
 
{{Tip|The option {{ic|1=Type=idle}} will delay the service startup until all jobs (state change requests to units) are completed. When using {{ic|1=Type=simple}}, the service will be started immediately, but boot-up messages may pollute the login prompt. This option is particularly useful when [[Start X at Login|starting X automatically]]. To use this option, add {{ic|1=Type=simple}} into {{ic|autologin.conf}}.}}
 
 
 
If you want to use other ''tty'' than ''tty1'' see [[Systemd FAQ#Q:_How_do_I_change_the_number_of_gettys_running_by_default.3F|Systemd FAQ]].
 
 
 
=== Serial console ===
 
 
 
Create the following file (and the leading directories):
 
 
 
{{hc|/etc/systemd/system/serial-getty@ttyS0.service.d/autologin.conf|2=
 
[Service]
 
ExecStart=
 
ExecStart=-/sbin/agetty --autologin ''username'' -s %I 115200,38400,9600 vt102
 
}}
