Hanko

What it does

Hanko is a lightweight open source user authentication solution that takes you on the journey beyond passwords. For better security, increased conversion rates, and happier users. Build your next-gen login in minutes – and never look back.

Open source, privacy-first, and built to scale. Hanko is the fastest way you integrate passkeys, 2FA, SSO, and more, with full control over your data. Move between self-hosted and Hanko Cloud anytime. No lock-in. Just auth how it should be: secure, fast, user friendly, and fully yours.

Hanko is developed by a Germany-based company and can be used with EU hosting or self-hosted infrastructure. For teams in Europe, this means more control over user data, authentication infrastructure, and long-term vendor dependency. For teams outside Europe, it simply means open source authentication with strong privacy and security defaults. Building a new app from scratch?

  Hanko – Open-Source Auth and User Management for the Passkey Era2025 · hanko.io · ▲11

  Hey HN! I'm excited to introduce Hanko, a passkey-first authentication platform that allows you to integrate authentication and user management into your apps with minimal effort, all via pre-built components and a flexible API. The origins of the project date back almost 10 years, when we started working on “replacing the password” with a push-based, white-label authenticator app. Early on, we came across the FIDO standards, which eventually became what we know today as passkeys. As big fans of passkeys, we always knew that we wanted to build solutions for other developers to make the…

  Talanoa▲340

  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…

  Pornpen.ai – AI-Generated Porn▲711

  Hey HN, I've been working on https://pornpen.ai, a site for generating adult images. Please only visit the site if you are 18+ and willing to look at NSFW images. This site is an experiment using newer text-to-image models. I explicitly removed the ability to specify custom text to avoid harmful imagery from being generated. New tags will be added once the prompt-engineering algorithm is fine-tuned further. If the servers are overloaded, take a look at the feed and search pages to look through past results. For comments/suggestions/feedback please visit…
