Auth0: sovereignty score and 8 European alternatives

Auth0 is an authentication and authorisation platform for developers. It lets teams add login to applications and APIs without building the identity layer themselves. Documented capabilities include sign-in with username, email, phone or social accounts, single sign-on, SAML, passwordless login, multi-factor authentication, OAuth 2.0 API security, federation with enterprise directories, role-based access control, user management and detection of breached passwords. Auth0 is delivered as a cloud service and is mainly used for customer-facing identity.

Okta, Inc., a US company headquartered in San Francisco, completed its acquisition of Auth0 on 3 May 2021, and Auth0 operates as a business unit within Okta. This means that Auth0 falls under US law, including the CLOUD Act, which can apply to data held outside the United States. Auth0 is proprietary software. For a European organisation, customer identities and login data are personal data, so the tenant region, data processing agreement and support access arrangements should be confirmed with Auth0 before adoption.

Why digital sovereignty matters with Auth0

Auth0 is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Auth0 hosts data in US, EU. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

Auth0 is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Auth0 together with your other vendors and gives a total score, a heatmap and the main risk drivers.
