Hanko

Hanko is a passkey-first, open-source authentication platform that serves as a modern alternative to Auth0, Clerk, and WorkOS. It provides a REST API covering passkeys (WebAuthn/FIDO2), passwords, OAuth social login, SAML SSO, multi-factor authentication, and session management. Hanko is available as a managed cloud service and as a self-hosted open-source deployment, targeting developers who want to add passwordless authentication to their applications. The platform is headquartered in Germany and emphasizes privacy-first, European-hosted infrastructure with a free tier supporting up to 10,000 monthly active users.

Hanko publishes 21 APIs on the APIs.io network, including Audit Logs API, Credentials API, Email Management API, and 18 more. Tagged areas include Authentication, Passkeys, WebAuthn, FIDO2, and Identity.

The Hanko catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Hanko’s developer surface includes authentication, documentation, engineering blog, pricing, and 12 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/hanko: open an issue to ask a question, or submit a pull request to add artifacts.
