Basically every local service is accessed via a web interface, and every interface wants a username and password. Assuming none of these services are exposed to the internet, how much effort do you put into security here?
Personally, I didn’t really think about it when I started. I make a half-assed effort at security where I don’t use “admin” or anything obvious as the username, and I use a decent-but-not-industrial password - but I started reusing the u/p as the number of services I’m running grew. I have my browsers remember the u/ps.
Should one go farther than this? And if so, what’s the threat model? Is there an easier way?
Same way I do at work. Different accounts and passwords for each service internally. Any service exposed to the net (game and email servers mostly) is on a segregated network and each machine has unique credentials to help prevent lateral movement. Self hosted Bitwarden tracks it all.
I do it for the same reason I require outbound firewall rules for almost everything on my home network - I’m a masochist.
