Privacy-first, framework-agnostic authentication and user management platform
Hanko delivers a lightweight, API-first authentication suite supporting passwords, passkeys, MFA, OAuth, SAML and social logins, with customizable web components and self-hosted or cloud options.
Hanko is a privacy‑first authentication and user‑management solution built on an API‑first, lightweight Go backend. It supports a full spectrum of modern auth methods—passwords, passkeys, MFA, OAuth social logins, and SAML—allowing developers to craft passwordless, mixed, or traditional flows.
The platform is framework‑agnostic: developers can embed ready‑made Hanko Elements web components or use the hanko‑frontend‑sdk to build custom UIs. Deployment is flexible; the backend can run on bare metal or Docker, and a fully managed Hanko Cloud service is available for teams that prefer not to self‑host. Comprehensive documentation, example apps, and community channels help accelerate adoption.
Beyond core authentication, Hanko offers server‑side sessions with remote revocation, webhooks, and customizable OIDC/OAuth connections. Upcoming features include organization management, role‑based permissions, and native mobile SDKs, positioning Hanko as a scalable foundation for both B2C and B2B identity needs.
When teams consider Hanko, these hosted platforms usually appear on the same shortlist.
