Trying to add in a second user (not for my use) to server
I am trying to add a new user to an existing droplet that already has a root user that requires a key for login. Originally I wanted the new user to be able to log in with a key too for security, but I guess I am a dumb ass because I have no idea what the tutorials regarding SSH Keys are trying to get me to do (except the ones that only show you how to add one to root, but those are currently useless to me). At this point, I'd be willing to call it a success if I could even get a new user that works without requiring a key but despite not doing anything to the user except creating it, I cannot seem to get it to log in as it wants a key for that user.
At this point I am grasping at strawing and pulling out my hair. I have no idea what to do and no idea what to do past this.
