What it does

Unphishable, zero-touch two-factor logins

No more mistyping, missing 30 second windows, or waiting endlessly for that SMS. Krypton securely pairs with your computer so that you don't have to touch your phone for each sign-in. Optionally, enable One tap sign-ins for enhanced security. SMS and authenticator app codes can easily be phished. Don't let that happen to you. Krypton protects you from phishing. Setting up two-factor can be time consuming and repetitive. Just scan once with Krypton. Krypton implements the standardized FIDO Universal 2nd Factor (U2F) protocol to provide secure, un-phishable two-factor authentication on the web, using just your phone. Krypton is built on top of an end-to-end verified and encrypted…from krypt.co

    Hi HN — I’m a heavy OpenClaw user and, like many others, I’ve been thinking about how to give these new “unleashed” agents secure access to my accounts. Agents need API access to be useful. But API keys are long-lived secrets. And agents are not secure environments. So I built something for myself that quickly turned into a product: keychains.dev. The idea is simple: agents never see raw credentials. With Keychains.dev: • Agents make API calls via a drop-in replacement for curl or JavaScript’s fetch() • They use template variable names instead of embedding credentials • The request is…

    Hi 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…
