Toggle to skip login (you already login once and then skip).

[ageofcodes]

The solution now is to go to /etc/greetd/cosmic-greeter.toml and change

[default_session]
command = "cosmic-greeter-start"
user = "cosmic-greeter"

to

[default_session]
command = "cosmic-session"
user = "username".

It would be a great QOL to just have a toggle in settings menu. Maybe under system->users.
