European alternatives to Auth0
Identity and access management from EU vendors

Auth0 is an identity and access management platform from the United States, acquired by Okta in 2021. Developers use it to hand off login to a hosted service: social and enterprise sign-in, single sign-on across applications, multi-factor authentication, user directories and standards such as OAuth 2.0, OpenID Connect and SAML. It removes the need to build and maintain password handling and session logic yourself.
An identity provider holds the account records of everyone who uses your product, and it sits on the critical path of every login, so both jurisdiction and availability come into the decision. A European alternative to Auth0 gives you that component from a supplier inside the EU or EFTA. ZITADEL and cidaas offer managed identity platforms, Keycloak is the open source project many teams run themselves, and Bare.ID provides it as a managed service.

Can I migrate users away from Auth0?
User migration usually means exporting the user records and importing them into the new system, with password hashes carried across where the formats allow it. ZITADEL and Keycloak document their import options, so plan a fallback login path for the changeover.
Which European alternative is closest to Auth0?
ZITADEL and cidaas are the nearest in shape as managed identity platforms with the usual standards support. Keycloak covers much of the same ground if you are willing to operate it.
Do these support single sign-on standards?
OAuth 2.0, OpenID Connect and SAML are the common vocabulary of this category, and products such as Keycloak, ZITADEL and Hanko are built around those standards. Check each vendor's documentation for the specific flows and extensions your applications need.
