What is Hanko?

Hanko GmbH is a Germany-based software company specializing in commercial open source authentication and user management solutions. Our customers are typically developers, product teams, and companies building web or mobile applications that require secure user authentication.

The main product, Hanko, is an open source authentication and user management system built around a flexible API. It supports multiple authentication methods, including passwords, passkeys, two-factor authentication (2FA), single sign-on (SSO), and Hanko Elements — a set of lightweight, framework-agnostic web components for fast integration into any website or application.

What products does Hanko offer?

Hanko provides two core products:

‍Hanko – our complete authentication solution, combining a flexible Go-based API for authentication and user management with Hanko Elements, framework-agnostic web components that deliver a ready-to-use authentication frontend within minutes. Hanko emphasizes privacy, phishing protection through passkeys, and ease of integration. The API can also be used directly to power custom frontend or mobile app authentication flows.

‍Passkey API – a standalone, FIDO2-certified passkey server that adds passkey / WebAuthn support to any login system. It also powers Hanko’s own passkey implementation.

Both products are:
‍
- Open source (AGPLv3, MIT) and available for self-hosting on GitHub
- Offered via Hanko Cloud, our fully managed SaaS platform

What is special about Hanko?

Hanko is built on a privacy-first approach:

- Data minimalism – only the essentials are stored
- Phishing-resistant authentication – passkeys and FIDO security keys
- Open source and FIDO2-certified – verified by the FIDO Alliance

With Hanko, you retain full control over your authentication stack and can switch seamlessly between self-hosted deployments and Hanko Cloud.

Thanks to Hanko Elements, our standard-based web components, Hanko is framework-agnostic and easy to integrate into any web application.
