I feel like a lot of the comments here do not understand how KeePassXC actually works. It’s a client application that works with a standard encrypted file format. The file format is the basis for security, not the client application.
KeePassXC does not store any data. Nor does it receive connections from the Internet, like a server. Thus the risk is structurally lower than a commercial client-server application like LastPass or 1Password, which is actually in possession of your password data.
I use 1Password at work for its excellent collaboration features and good-enough security. For most people it replaces a post-it note or Excel file. It’s way better than those.
But for my passwords I use KeePass (the file format) and a variety of clients including KeePassXC. This statement about AI won’t change that, unless someone can give me a reason other than vague “AI bad” or “no vibe coding” like most comments so far.
I think a lot of folks end up copying their encrypted file to shared storage like Dropbox anyway. This doesn’t seem all that different from using 1pass.
Sorry but that is nonsense. "The file format is the basis for security, not the client application" is so wrong, any messing with the application is game over.
Hell if you leave your computer unlocked, a rubber-ducky could replace your executable and middleman your master password.

No, some projects take fundamental issues with AI, be it ethical, copyright related, or raising doubts over whether people even understand the code they're submitting and whether it'll be maintainable long term or even work.
There was some drama around that with GZDoom: https://arstechnica.com/gaming/2025/10/civil-war-gzdoom-fan-... (although that was a particular messy case where the code broke things because the dev couldn't even test it and also straight up merged it; so probably governance problems in the project as well)
But the bottom line is that some projects will disallow AI on a principled basis and they don't care just about the quality of the code, rather that it was written by an actual person. Whether it's possible to just not care about that and sneak stuff in regardless (e.g. using autocomplete and so on, maybe vibe coding a prototype and then making it your own to some degree), or whether it's possible to use it as any other tool in development, that's another story.
Edit: to clarify my personal stance, I'm largely in the "code is code" camp - either it meets some standard, or it doesn't. It's a bit like with art - whether you prefer something with soul or mindless slop, unfortunately for some the reckoning is that the purse holders often really do not care.
> No, some projects take fundamental issues with AI, be it ethical, copyright related, or raising doubts over whether people even understand the code they're submitting and whether it'll be maintainable long term or even work.
These issues are no different for normal submissions.
You are responsible for taking ownership and having sorted out copyright. You may accidentally through prior knowledge write something identical to pre-existing code with pre-existing copyright. Or steal it straight off StackOverflow. Same for an LLM - at least Github Copilot has a feature to detect literal duplicates.
You are responsible for ensuring the code you submit makes sense and is maintainable, and the reviewer will question this. Many submit hand-written, unmaintainable garbage. This is not an LLM specific issue.
Ethics is another thing, but I don't agree with any proposed issues. Learning from the works of others is an extremely human thing, and I don't see a problem being created by the fact that the experience was contained in an intermediate box.
The real problem is that there are a lot of extremely lazy individuals thinking that they are now developers because they can make ChatGPT/Claude write them a PR, and throw a tantrum over how it's discriminating against them to disallow the work on the basis that they don't understand it.
That is: The problem is people, as it always has been. Not LLMs.
Yes absolutely relevant, especially in this software case. There is no requirement for mass-amounts of boilerplate code to be written here, just supposedly smart and correct cryptography and as little code as possible to do the job right... so if someone is using AI... that is a huge red flag.
An obvious sign that something is going horribly wrong in this project.
In fact i think this kind of news is enough to garner a huge influx of international hackers all targeting this package now, if they weren't already. They will be looking closely at the supply chain, phishing the hell out of the developers, physical intrusions where they can, its a hint that the developers might be stressed and making poor decisions, with huge payoff for infiltrating
I would agree, IMHO keepassXC should however actually lay out their review standards better to actually be able to review security relevant code. I am a happy keepassxc user on multiple devices. However, trying to use and extend it in various settings, I simply still do not understand their complete threat model, which makes it very difficult to understand the impact of many of extensions it provides: being it for quick unlocking or API connection to browsers that can be used for arbitrary clients.
People get confused talking about AI. For some reason they skip the fact that a human prompted the LLM for the generated output. One could almost think AI is an agent all on its own.
>Whether it was generated by human or AI is irrelevant.
No. These systems are still so mindboggingly bad at anything that involves manual memory management and pointers that even entertaining the idea of using them for something as critical as a non-trivial large c++ codebase, for a password manager no less, is nuts. It displays a lack of concern for security and propensity for shortcuts that I don't want to touch anything by people who even remotely consider this appropriate.
> We take no shortcuts. At KeePassXC, we use AI for
Followed by shortcuts
> As such, they are a net benefit and make KeePassXC strictly safer.
They can also waste author's/reviewer's time chasing imaginary ends, taking time away from the "regular" review, or with some level of trust add some plausibly explained vulnerability. Nothing is strict here
I'm sure if you ask your favorite AI bot, he'll come up with a few more reasons why the statement is overconfidently wrong.
If we're wasting anyone's time, it's our own. Your comment reads like the AI would make up hundreds of invalid complaints, which is simply not true. You can see for yourself in our GitHub repository if you care.
There's no way to determine whether a contributor used LLMs in part or full, not without them being honest about it. With that in mind, this seems like a reasonable position. Been using KeePassXC since forever and will continue to do so. It might feel wrong to some, but these changes are inevitable and it's best to be prepared and become acquainted with that now rather than later.
I am now on the hunt for a non vibe coded alternative. I stopped open sourcing code after all my open code's licenses were broken by Microsoft and everyone else commercialising it. Which I guess is part of the point of why they did it and have put serious money to defending themselves in court against anyone that dare challenge it. Suffice to say I don't want anything to do with projects that participated in that theft and re-commercialisation of open source code.
Does not look like the original Keepass project is doing this which is the easiest migration away but I will check a bit deeper on their commits to be sure.
The original Keepass project has 11 CVEs. XC has 3, and has disputed all of them with e.g. "the vendor disputes this because memory-management constraints make this unavoidable in the current design and other realistic designs", etc.
Additionally, the original KeePass project has no public development or public review process for their code. They do everything behind the scenes and only publish code when a release is made. KeePass is "code available" open source.
This just wrecked my trust in KeePassXC. Time to go see if anyone's going to continue this from a fork where they aren't setting themselves up for a massive security failure of some variety.
I didn't know about that and this is really concerning to me. AI has no place in security critical software like KeePassXC, and I remain unconvinced that they will only use it for simple tasks. I don't feel like I can trust this software any longer this is a password manager not just some random website where bugs basically don't matter. I hate that I have to replace yet another piece of software that I liked.
That's all nice but I still don't want slop code in an application as security critical as a password manager. The correct percentage of slop code for a password manager is 0% and it’s pants on head crazy to claim otherwise.
I have dug around a bit and found a thread mastodon thread that doesn't inspire confidence[1]. KeePassXC seems completely untrustworthy at this point not only have they jumped on the AI bandwagon, they also seemingly don't know what a zero-day is. I genuinely liked KeePassXC and used it for years now I am spending my Sunday evening researching alternatives.
I think there's an analogous subset: "llm-security theater".
There's so much pearl-clutching, pedantry, and noise from people who are obviously 1) not contributing to KeePassXC AND 2) never would contribute AND 3) are unaware of EXISTING bugs/issues/CVEs with KeePassXC. All they provide are vague abstract arguments from their own experience with LLMs, and they argue with the maintainers of KeyPassXC without giving specifics, as though they have the right to tell others how to run their repo when they're unable to link a single concrete problematic issue or PR.
Instead, all they have are "vibes", which is ironic.
My great concern with regards to AI use is that it's easy to say "this will not impact how attentive I am", but... that's an assertion that one can't prove. It is very difficult to notice a slow-growing deficiency in attentiveness.
Now, is there hard evidence that AI use does lead to this in all cases? Not that I'm aware of. Just as there's no easy way to prove the difference between "I don't think this is impacting me, but it is" and "it really isn't".
It comes down to two unevidenced assertions - "this will reduce attentiveness" vs "no it won't". But I don't feel great about a project like this just going straight for "no it won't" as though that's something they feel with high confidence.
you have decades of experience of reviewing code produced at industrial scale to look plausible, but with zero underlying understanding, mental model or any reference to ground truth?
glad I don't work where you do!
it's actually even worse than that: the learning process to produce it doesn't care about correctness at all, not even slightly
the only thing that matters is producing plausible enough looking output to con the human into pressing "accept"
(can you see why people would be upset about feeding output generated by this process into a security critical piece of software?)
The statement that correctness plays no role in the training process is objectively false. It's untrue for text LLMs, even more so for code LLMs. Correct would be that the training process and the architecture of LLMs cannot guarantee correctness.

I can see a few differences.
Pushing Keepass vault to cloud storage:
* No per-item synchronisation
* Full control over encryption of the database
* Choice of cloud storage to trust with vault
* Free as in beer if no using cloud (or using a free/already paid for offering)
1Password:
* Per-item sync and collaboration
* Full trust on the (closed-source) client apps over encryption of vault
* No choice of cloud
* No choice of encryption
* Mandatory paying subscription
Sorry but that is nonsense. "The file format is the basis for security, not the client application" is so wrong, any messing with the application is game over.

I choose not to use a vibe coded password manager, rigorous review or not, to protect my entire digital existence, monetary assets and reputation.
It's the pinnacle of safety requirements, memory unsafe language, cryptography, incredibly high stakes.
I have the distinct displeasure having to review LLM output in pull requests and unfailingly they contain code the submitted doesn't fully understand.

Y'know how there's "security theater"? https://en.wikipedia.org/wiki/Security_theater

if this was true why the need to point out "we're not vibe coding", and create this process around it?
fork and move on
We did not create this process for AI, it has been our process since 2016.
> we still code ourselves for work and for fun. This will not suddenly go away because we have another tool in our belts.
AI is just another way to write code. At the end of the day code is just text. It still needs to be reviewed - nothing about that is changing.
My great concern with regards to AI use is that it's easy to say "this will not impact how attentive I am", but... that's an assertion that one can't prove. It is very difficult to notice a slow-growing deficiency in attentiveness.

> From where does that confidence come?
From decades of experience, quite honestly.
How can you have decades of experience in a technology less than a single decade old? Sounds like ones of those HR minimum requirement memes
Decades of programming and open source experience.
you have decades of experience of reviewing code produced at industrial scale to look plausible, but with zero underlying understanding, mental model or any reference to ground truth?

this statement is objectively false.
I'm just an AI researcher, what do I know?

me too! what do I know?
(at least now we know where the push for this dreadful policy is coming from)
The whole purpose RLVR alignment is to ensure objectively correct outputs.
