  • Looking at keepassXC doc I couldn’t find such setup. Maybe it’s possible, but maybe it also leads to trouble down the road. The “official way” seems to use cloud storage.

    You keep saying external server for syncthing, but again: syncthing does direct data transfers, encrypted end to end, between devices.

    I mention that but with a specific context.

    • people with certain ISPs will need to use the relay transfer feature because direct connections can’t be established. Similarly, if you work in an office and you use the corporate network, you usually can’t have device-to-device working (can be both from a technical POV and from a policy POV).
    • even with 0 data transfers, servers still have some trust in establishing your direct connections. I know that syncthing uses keys to establish connections, but that’s why I mentioned CVEs. If there is one, your sync connection could be hijacked and sent elsewhere. It’s a theoretical case, I don’t think it’s very likely, but it’s possible. The moment you have a server doing anything, you are extending trust.

    In those cases then yes, you are extending a bare minimum trust, and you fully encrypted data would temporarily pass on the relay’s RAM

    And from my (consumer) PoV this is functionally equivalent to have the data stored on a server. It might not be all the data (at once), it might be that nobody dumps the memory, but I still need to assume that the encrypted data can be disclosed. Exactly the same assumption that should be made if you use bitwarden server.

    If this makes you paranoid

    Personally it doesn’t. As I said earlier, it’s way more likely that your entire vault can be taken away by compromising your end device, than a sophisticated attack that captures encrypted data. Even in this case, these tools are built to resist to that exact risk, so I am not really worried. However, if someone is worried about this in the case of bitwarden (there is a server, hence your data can be disclosed), then they should be worried also of these corner cases.

    I just get nothing from Bitwarden that syncthing and KeePass don’t offer more easily.

    You can say many things, but that keepass + syncthing is easier is not one of them. It’s a bespoke configuration that needs to be repeated for each device, involving two tools. bitwarden (especially if you use the managed service) works out of the box, for all your devices with 0 setup + offers all features that keepass doesn’t have (I mentioned a few, maybe you don’t need them, but they exist).

    I don’t know how or why you would have vault conflicts, but it really does sound like something fixable

    At the time I did not use syncthing, I just used Drive (2014-2017 I think), and it was extremely annoying. The thing is, I don’t want to think about how to sync my password across devices, and since I moved to bitwarden I don’t have to. This way I don’t need to think about it, and also my whole family doesn’t have to. Win-win.

    That said, if you are happy with your setup, more power to you. I like keepass, I love syncthing, I have nothing against either of them. I just came here to say that sometimes people overblow the risk of a server when it comes to a password manager. Good, audited code + good crypto standards means that the added risk is mininal. If you get convenience/features, it’s a win.


  • Agree on the versioning issue. In fact I mentioned that the issue is convenience here. It is also data corruption, but you probably are aware of that if you setup something like this. Manually merging changes is extremely annoying and eventually you end up forgetting it to do it, and you will discover it when you need to login sometime in the future (I used keepass for years in the past, this was constantly an issue for me). With any natively sync’d application this is not a problem at all. Hence +1 for convenience to bitwarden.

    However KeePassXC’s sync feature does sync the vault.

    How does it work though? From this I see you need to store the database in a cloud storage basically.

    For mobile I just give syncthing full permission to run in the background and have never had issues with the syncing on the folders I designate.

    I use this method for my notes (logseq). Never had synchronization problem, but a lot of battery drain if I let syncthing running in the background.

    Nothing else passes through it unless you opt into using relaying in case you have NAT issues.

    I guess this can be very common or even always the case for people using some ISPs. In general though, you are right. There is of course still the overall risk of compromise/CVEs etc. that can lead to your (encrypted) data being sent elsewhere, but if all your devices can establish direct connections between each other, your (encrypted) data is less exposed than using a fixed server.

    If you are paranoid, the software is open source and you can host your own relays privately,

    This would also defeat basically all the advantages of using keepass (and family) vs bitwarden. You would still have your data in an external server, you still need to manage a service (comparable to vaultwarden), and you don’t get all the extra benefits on bitwarden (like multi-user support etc.).

    To be honest I don’t personally think that the disclosure of a password manager encrypted data is a big deal. As long as a proper password is used, and modern ciphers are used, even offline decryption is not going to be feasible, especially for the kind of people going after my passwords. Besides, for most people the risk of their client device(s) being compromised and their vault being accessible (encrypted) is in my opinion way higher than -say- Bitwarden cloud being compromised (the managed one). This means that for me there are no serious reasons to use something like keepass (anymore) and lose all the convenience that bitwarden gives. However, risk perception is personal ultimately.


  • Few reasons, with the most important being convenience. Syncthing is going to see just a binary blob as the password storage is encrypted. This means it is impossible for syncthing to do proper synchronization of items inside the vault. Generally this is not a problem, but it is if you happen to edit the vault on multiple devices and somehow syncthing didn’t sync yet the changes (this is quite common for me on android, where syncthing would drain the battery quite quickly if it’s always actively working). For bitwarden on the other hand the sync happens within the context of the application, so you can have easy n-way merge of changes because its change is part of a change set with time etc.

    Besides that, the moment you use syncthing from a threat model point of view, you are essentially in the same situation: you have a server (in case of syncthing - servers) that sees your encrypted password data. That’s exactly what bitwarden clients do, as the server only has access to encrypted data, the clients do the heavy lifting. If the bitwarden server is too much of a risk, then you should worry also of the (random, public, owned by anybody) servers for syncthing that see your traffic.

    Keeshare from my understanding does use hosting, it uses cloud storage as a cloud backend for stateful data (Gdrive, Dropbox etc.), so it’s not very different. The only difference would be if you use your private storage (say, Synology Drive), but then you could use the same device to run the bit/vaultwarden server, so that’s the same once again.

    The thing is, from a higher level point of view the security model can only be one of a handful of cases:

    • the password data only remains local
    • the password data is sync’d with device-to-device (e.g. ssh) connections
    • the password data is sync’d using an external connection that acts as a bridge or as a stateful storage, where all the clients connect to.

    The more you go down in the list, the more you get convenience but you introduce a bit of risk. Tl;Dr keepass with keyshare/syncthing has the same risks (or more) than a Bitwarden setup with bitwarden server.

    In addition to all the above, bitwarden UX is I would say more developed, it has a better browser plugin, nice additional tools and other convenience features that are nice bonuses. It also allows me to have all my family using a password manager (including my tech illiterate mom), without them having to figure out anything, with the ability to share items, perform emergency accesses etc.

    Edit: I can’t imagine this comment to be deemed off topic, so if someone downvoted simply to express disagreement, please feel free to correct or dispute what I wrote, as it would certainly make for an interesting conversation! Cheers






  • I am not sure I understood. You called some mod by name and they removed the comment? If that’s the case, I perfectly understand and agree with the decision tbh.

    That said, this is a general argument, not referred to any particular mod. I think that many people get angry when their content is moderated and they might want to harass/argue/avenge against the mod who took that action.


  • I complain about people who support Soviet-style dictatorships having full control over online platforms moderating exactly as one would expect

    I will ask in good faith: given that those people started the whole project to have that space, but built it using federated technologies which allow others to run their places, what is exactly the basis for your complaint? As absurd as they might be, instances can decide their own moderation policies, whether you or I agree with them or not. Given the fundamentally distributed nature of this platform, there is no such thing as “having full control”, and instead we can choose instances based on our preferences, so we are free to not subject ourselves to those policies, they are free to do, and both a free to use the platform in the way we use. The code is open, there are plenty of other instances. What exactly is the complaint here?


  • It does, but it’s an online forum, not an essential service, and easy to replace. On the other hand, being there with your name or nickname exposes you to harassment from those pissed at you for your decision.

    I would say it’s an acceptable evil given the circumstances.

    As a side note: asking why after a mod action is almost universally pointless. Moderating is free work and a level of subjectivity is implied. I think not having the ability to argue is infuriating but understandable.

    I see absolutely no reason why you couldn’t be a Dev and an admin, in a decentralized platform. If this was a single-server platform, maybe. But here, how does the moderation policy of lemmy.ml affects anything but posts over there?

    Also, beehaw has a very politicized banning policy, would you say that is unacceptable? I see it as perfectly fine and I would be fine as well if they were to contribute to Lemmy code (unless they try to build their policies into the code and therefore enforce them everywhere - which is something we know the Lemmy devs are not doing).


  • I am a security engineer by profession, so I do have at least a decent understanding of what I am talking about. Every server in this case has that potential. There is nothing preventing any admin from patching code and manipulating the network after TLS termination (I.e., changing payloads of POST requests etc.). That said, not even in a videogame you would be “locked up” by someone posting CP on your behalf like that. This is simply not a threat and if you think it is, then you should be worried about every website you visit.







  • They were openly discouraging people to sign up on .ml already a year ago (I remember a banner to register elsewhere). I don’t think “anything” in particular is working. The devs seem not to care less for having the biggest instance, or communities there etc. They had the instance long before most of Lemmy users joined, after all.

    There are serious cyber security implications here that people are sleeping on

    No, there are not.

    At most, if they decide to kill the project by adding malicious code they can affect Lemmy itself. 99% of users don’t run Lemmy (which is where the “quiet exploits” would run), and the frontend simply doesn’t allow you to have a serious impact, unless you think they will stumble upon a browser 0-day and they decide to burn it by committing the exploit to an open source repo instead of selling it for millions (or use it elsewhere).

    What’s with the fearmongering? Their stance is crystal clear since ever.

    possibly even fork the Lemmy repos

    Right, and who maintains the fork? Who, among the large population of external contributor, I mean?
