Hi, in this blog post, i will showcase how you can configure your getty systemd service so that, you are able to login without entering your username. This is really helpful if you are the only one that uses the system. If multiple people use your system, you can still use this method by assiging each "person" a seperate tty to login to the computer.
This method has been tested on Arch Linux. (systemd)
First, you need to edit the
sudo vim /firstname.lastname@example.org (if you do not know how to use vim, use nano or any other editor)
Check for the line which starts with
ExecStart= and replace it with
ExecStart=-/sbin/agetty -n -o <username> %I
Make sure to change
<username> to which ever username you want as the default.
Instead of editing
email@example.com, you edit the file for the tty you want. ie,
getty2.service for example
Now you should be able to see a prompt like this when you reboot
