This whole reply, and every other "anecdote" reply is more worthless than the pixels its printed on, without a link to your "actually did a good job" password manager.

(wow funny how these vibe code apps always are copies of something theres many open source versions of already)

Ugh, you made me spend the 20 minutes it takes to spin up a new github account to share this (my existing one uses my real name and I don't really want to doxx myself that much. Not that it's a huge deal, my real identity and the "ninkendo" handle have been intertwined a lot in the past.)

https://github.com/ninkendo84/kenpass

I'm not saying it's perfect, there's some things I would've done differently in the code. It's also not even close to done/complete, but it has:

- A background agent that keeps the unsealed vault in-memory

- A CLI for basic CRUD

- Encryption for the on-disk layout that uses reasonably good standards (pbkdf2 with 600,000 iterations, etc)

- Sync with any server that supports webdav+etags+mTLS auth (I just take care of this out of band, I had the LLM whip up the nginx config though)

- A very basic firefox extension that will fill passwords (I only did 2 or 3 rounds of prompting for that one, I'm going to add more later)

Every commit that was vibe-coded contains the prompt I gave to Codex, so you can reproduce the entire development yourself if you want... A few of the prompts were actually constructed by ChatGPT 5.2. (It started out as a conversation with ChatGPT about what the sync protocol would look like for a password manager in a way that is conflict-free, and eventually I just said "ok give me a prompt I can give to codex to get a basic repo going" and then I just kept building from there.)

Also full disclosure, it had originally put all the code for each crate in a single lib.rs, so I had it split the crates into more modules for readability, before I published but after I made the initial comment in this thread.

I haven't decided if I want to take this all the way to something I actually use full time, yet. I just saw the 1password subscription increase and decided "wait what if I just vibe-coded my own?" (I also don't think it's even close to worthy of a "Show HN", because literally anybody could have done this.)

Thank you for the time commitment based on an internet forum comment. I appreciate greatly the succinct human written README.

Did you investigate prior art before setting out on this endeavor? https://www.google.com/search?q=site%3Agithub.com+password+m...

I ask because engineers need to be clever and wise.

Clever means being capable of turning an idea into code, either by writing it or recently by having the vocabulary and eloquence to prompt an LLM.

Wisdom means knowing when and where to apply cleverness, and where not to. like being able to recognize existing sub-components.

		> Did you investigate prior art before setting out on this endeavor Lol no, I had no idea there was any other password managers! Thanks for the google search link! I didn't know search engines existed either! > Wisdom means knowing when and where to apply cleverness, and where not to. like being able to recognize existing sub-components. It says literally in the README that part of this is an exercise in seeing what an LLM can do. I am in no way suggesting anyone use this (because there's a bazillion other password managers already) nor would I even have made this public if you hadn't baited me into doing it. The fact that there's a literal sea of password managers out there is why I'm curious enough to think "maybe a one that I get to design myself, written to exactly my tastes and my tastes alone could be feasible", and that's what this exercise is about. It literally took me less time to vibe-code what I have right now, than to pour through the sea of options that already exist to decide which one I should try. And having it be mine at the end means that I can implement my pet features the way I want, without having to worry one bit about fighting with upstream maintainers. It's also just fun. I thoroughly enjoy the process of thinking about the design and iterating on it.
