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; methods for starting an [[Xorg|X server]] are described in [[Start X at Login]].
+
 
+
== Service ==
+
Create a new service file similar to {{ic|getty@.service}} by copying it to {{ic|/etc/systemd/system/}}:
+
 
+
# cp /usr/lib/systemd/system/getty@.service /etc/systemd/system/autologin@.service
+
 
+
{{Note|{{ic|/etc/systemd/system/}} takes precedence over {{ic|/usr/lib/systemd/system/}}.}}
+
 
+
Then change the {{ic|ExecStart}} line to include the {{ic|-a ''USERNAME''}} parameter:
+
 
+
{{hc|/etc/systemd/system/autologin@.service|
+
2=[Service]
+
''[...]''
+
ExecStart=-/sbin/agetty --noclear -a ''USERNAME'' %I 38400
+
''[...]''
+
 
+
[Install]
+
WantedBy=getty.target
+
}}
+
 
+
{{Tip|It is possible to change {{ic|1=Type=idle}} to {{ic|1=Type=simple}} and avoid delaying the execution of agetty until all jobs (state change requests to units) are completed. This option is more useful when [[Start X at Login|starting X automatically]]. See {{ic|man systemd.service}} for more info. {{Note|{{ic|1=Type=simple}} can cause systemd boot-up messages to pollute the login prompt.}}}}
+
{{Note|If you're using mingetty, simply replace /sbin/agetty to /sbin/mingetty}}
+
 
+
 
+
Finally, you need to disable the old {{ic|getty@tty''X''.service}} for the specified tty and enable the new {{ic|autologin@tty''X''.service}}. For example,
+
# systemctl daemon-reload
+
# systemctl disable getty@''tty1''
+
# systemctl enable autologin@''tty1''
+
# systemctl start autologin@''tty1''
+
 
+
{{Warning|If you are currently in an X session on the same tty configured in the service file, starting {{ic|autologin@tty''X''.service}} will kill your X server.}}
+
 
+
To avoid errors related to display-manager.service in dmesg, you should set the default target to multi-user instead of graphical:
+
# systemctl enable multi-user.target
+
(See also: [[Systemd#Change_default_target_to_boot_into|Change default runlevel/target to boot into]].)
