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?
Don’t remember the tool, maybe someone here does, but there’s some web service out there that boasts a “no storage” approach. You provide some URI and some other value (maybe username) and it makes a password for you, but it’s always the same for a given combination. Basically it’s a purely functional generator.
Downside would be forgetting a minor detail (Did it end with a slash or not? What was the username?) or the site going down. You can achieve the same thing yourself with a hash calculator but those passwords are a bitch to type in.
tl;dr just use KeePass
