Bulwark Passkey – A virtual Yubikey-like device for 2FA or WebAuthN
Hey y'all, This is something I've been working on for a few months. It is a passkey system, similar to Apple Passkeys or a Yubikey, but it is entirely software based so you can sync credentials between devices. Passkeys (and FIDO devices in general) allow you to use public keys instead of passwords or codes to authenticate. For instance, you can just click "Approve" on the device/software instead of having to copy a code, and there are no passwords to phish. This is a new piece of tech, so website support for logins are still limited, but it can currently be used for 2FA anywhere a…

In plain words
Bulwark Passkey is a software-based passkey system that functions like a Yubikey or Apple Passkeys, enabling two-factor authentication and WebAuthn login using public key cryptography instead of passwords or codes. Designed for developers and security-conscious users, it allows credentials to sync across devices while eliminating phishing risks through simple approval clicks rather than code copying. Currently compatible with services supporting Yubikey authentication, though website support for passkey logins remains limited.

Software-based WebAuthN/2FA
An open-source passkey manager for the future of passwordless logins. Bulwark Passkey allows you to experience the ease-of-use and security of passkeys without the need for a physical device. Passkeys are an industry standard that allows you to log into websites without passwords or codes. Bulwark Passkey is a virtual FIDO2 device, allowing you to test the latest industry standards without buying a hardware device, like afrom bulwark.id

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

I made a thing! In 2014, I was holding a stack of iPhones and thought to myself: "Hey, if I had each phone display a playing card, I could click a button and they'd shuffle themselves" I pared that idea all the way down to this: trading cards made of e-ink displays. Right now, each card costs me about $20 each, but with only a bit more scale, I think I can get that down to $10. In doing this project, I learned how to design electronics and circuit boards. I learned Rust and wrote my first driver, I upped my CAD skills, 3D printed, and did my first resin casting. I generated the images on the…
