In MA2 it was root:root, but in MA3 it doesn't much, anyone know what pass is correct?
There may be another way but I have gotten in via SSH by storing one of my public keys in the autherized_keys file on the desk. It's hard enough to do that I'm sure they don't want you going in that way.
I won't share how I did it since it requires you to do it after each reboot and to get modify a file in the desk without ssh access in the first place.
Perhaps in the future they will add UI to add an SSH key into the desk.
