24 alternatives to I built an open-source and serverless authentication system
I built Oxidiko because I was tired of seeing companies lose millions of passwords to sloppy authentication systems that were never designed for privacy or modern threats. I’m Jonathan, a 17-year-old developer and security enthusiast, and I wanted to create a simpler, more secure, and privacy-first way to log in. Oxidiko reduces the attack surface by eliminating central password storage, encrypting all vault data locally, and making the user’s identity portable — so even if your server is breached, there’s nothing meaningful to steal. It uses WebAuthn (passkeys) combined with a PIN fallback…

Nango (https://github.com/NangoHQ/nango) provides pre-built OAuth flows, secure token storage and automatic refreshes for 40+ APIs and counting. Why we built Nango: We built Nango to solve the pain of accessing OAuth APIs. Despite OAuth being a standard protocol in theory, it remains a major burden to implement it, even with the help of a library. You still need to add endpoints and logic to your app for the server-side dance, implement token refreshes, build & secure your token storage, deal with redirects on the frontend etc. But the worst part is that (almost) every…

Hi HN, We (myself, Adhyyan1252 and yush_g) are undergrad students that hacked out this side project last month during Hack Lodge[1] (the ideas and many of the underlying circuits for which came from the 0xPARC community[2])! We’re extremely excited to share this new primitive. Besides the technical challenges building this project that folks here would find interesting (fixing the ZK proof compiler, modifying nodeJS V8 params etc.), we think this is a very novel use case for ZK tech, and ECDSA inside ZK-SNARKs is a starting point that unlocks many other ideas! :D A summarized version of our…

Hey folks, Michael here. I have been working in this project on and of for about a year and a half and I finally got it into a state where I can share it.

The goal was to make it as easy as possible for you to get started and have a complete authentication solution without you having to configure anything. Project Website: https://auth.vulpo.dev The Project contains: - Auth Server (Rust) - Admin Dashboard - JS and…

I have been working on Sesame, an open-source password manager that keeps your vault local by default. You don't need an account to create or use a vault, and the hosted service never receives the vault itself. It's still early software and the independent security review isn't finished yet, so I am mainly interested in feedback, testing, and people looking through the code. (Linux support is yet to be released on v0.1.2, but currently is in the works.)

over this weekend myself and two of my friends took part in a hackathon and built this side-project. we have been diving into computer-use recently and developed an sdk to make it easy to implement for devs like us. one feature we were missing though, was the agent being able to log into services. anthropic understandably blocks this capability with their guardrails, and you wouldn't want your credentials to end up in any model context anyways. so we added a keychain service to the vm that the agent is using. it was built using the pass cli (https://www.passwordstore.org/).…
