What do you guys do about usernames / passwords for your local services? (lemmy.world)

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?

Just because each device has a globally routable IP address doesn't mean they can be accessed from outside your LAN. You still have to add a firewall rule to open a port to the device.

I was referring to the latest CVE for ipv6 where an attacker just sends a flood of IPv6 packets which puts things like WindowsOS into a mode for remote code execution, even via webpage. Windows remedy right now is turnoff all ipv6 capability, as they don't have a fix yet

do self hosters use Windows? i would have thought most people were running Linux

[–] [email protected] 2 points 2 months ago

I have seen both. Typically you expect somebody self hosting to be about privacy and freedom, and thus choosing Linux, but there are WinFans too

That still wouldn't get past your firewall

Apparently crafted webpage could be a vector. Router has to block fragmented packages also. The issue is non savvy people get shipped a router with Ipv6 firewall turned off (as a shit default setting) and don't know to check it. And as it is a worm type it can come in with otger binaries

That's a Windows problem, not an IPv6 problem.

Of course, but for a person with all machines on network having same user name and password it could become a larger problem
