There's this wild technology called a hotspot.

There's also this dated technology called a wired connection that some other dated technologies require. Since I don't get to choose every device I interact with or depend on, that's not always available.

That level of security is exactly the same as exposing your password manager to the "fucking" internet.

I would disagree. A Bitwarden instance identifies itself as such to every visitor that comes by. It advertises itself as a particularly high value target. By contrast, a lot of what a NextCloud instance hosts is often personal and more valuable to the user than a hacker, so it does not become clear if there's anything of value inside.

It also decreases the attack surface of my password manager itself because there are fewer features in it that may have a potential exploit. Even if an attacker compromises the NextCloud instance, that may grant access to the file itself, but they still have to contend with the entire security of the password manager. No device will ever make any contact with the server for password purposes other than to sync the database file, and there's no web interface to inject a password stealing JavaScript file.

EDIT: Forgot to mention the worst par about KeePassXC. It's vibecoded crap.

Hotspot does not imply that it needs to be wifi. You can share your internet connection via usb tethering too. (also a wild new technology, I know)

This ignores how modern internet attacks work. Hackers don't sit around manually browsing websites. Automated botnets scan the entire IPv4 address space 24/7 looking for specific software signatures or known unpatched vulnerabilities. If a Nextcloud exploit drops today, a bot will breach the server before the hacker even knows what is stored inside.

Also, advertises itself to whom? I'm not exposing it to the internet. How many reports can you find of people getting their Vaultwarden instance hacked? This is a lot of assumptions that don't track with reality.

You're putting your database file in nextcloud. That increases the attack surface of your solution, a lot.

That's *exactly *what a client for vaultwarden does...

there’s no web interface to inject a password stealing JavaScript file

Vaultwarden has a web interface, true. It's also true that I've literally never used it for anythin other than creating the users. I haven't opened it in years.

You're choosing a very petty and small hill to die on, dude. Just admit that you prefer doing it your way even if there are better alternatives.

Some environments restrict USB access for security reasons. Some environments don't have extra ports to spare. Sometimes, I just don't have the right cable on hand even if the environment is otherwise fine.

No, I'm well aware of that. I mean that when the inevitable scans come, the Vaultwarden instance will freely identify itself as such. An attacker would automate the breach if they detected my NextCloud instance and had an exploit ready, but then what? The contents are too unpredictable to have a one size fits all approach from there. Even if they scan all the servers they breach for password databases, they have to contend with the fact that they still have no means to try to intercept the password. They may have a slightly easier time obtaining the database, but cracking a huge pile of password databases is an infeasible task.

Also, advertises itself to whom? I'm not exposing it to the internet

Yes, if I did it the way you want, I could avoid exposing it and allowing it to advertise itself, but then I would be unable to access it without a VPN or other networking tool.

How many reports can you find of people getting their Vaultwarden instance hacked? This is a lot of assumptions that don't track with reality.

I never said that Vaultwarden had been hacked. I said essentially that Vaultwarden is a single point of failure that I do not want to risk exposing to the wider internet, and I don't want to hide the services behind a VPN because that can complicate access. It's a little less secure, but what's the point of security if I can't actually use it myself?

You're putting your database file in nextcloud. That increases the attack surface of your solution, a lot.

Of the overall system, yes. Of the password database itself, not really. Slightly less potential security through lack of access, but with a sufficiently secure password, cracking it isn't realistic. That becomes exponentially more true if you've got a huge pile of password databases you need to crack, as would most likely be the case for anyone who breached my server.

That's *exactly *what a client for vaultwarden does...

Yes, and you're just about get to the problem I have with the client if you'd finish my sentence before you got smug with me.

Vaultwarden has a web interface, true. It's also true that I've literally never used it for anythin other than creating the users. I haven't opened it in years.

And it's great that for your personal use case, that works our for you. But before you decide to act like a smug asshole, maybe consider that not every situation can resolve as cleanly as yours. There are a lot of reasons that restricting access to a VPN can at times be limiting. Sure, at home on your own hardware, not really, but some people need the same tools for different purposes in different environments.

You're choosing a very petty and small hill to die on, dude. Just admit that you prefer doing it your way even if there are better alternatives.

Just think beyond your own experiences and accept that other people have different needs than you for a variety of reasons that they can't always control.
