European Alternatives to Auth0
US developer-focused authentication and authorisation service, now part of Okta. Below are 12 alternatives from companies headquartered in Germany, France, Switzerland, Belgium, Finland and Denmark. 8 of them keep data in the EU only, and 3 have a free plan.
Headquartered in Europe
Every company listed here has its headquarters in the EU, EEA, UK or Switzerland, not just a data centre there.
Data location you can check
The pricing table shows whether each one keeps data in the EU only, offers an EU region, or does not say.
Outside the US CLOUD Act
US providers can be ordered to hand over data held in their European data centres. A European company with no US parent or US operations is outside that reach.

What to Check Before Switching from Auth0
Where your data will be stored
8 of the 12 alternatives here say they keep data in the EU only. Cloud IAM, Nevis, Ory and Purse offer an EU region alongside others, so choose it explicitly when you set up the account.
How you can try it
Hanko, Ory and FoxIDs have a free plan, so you can run a real test before cancelling Auth0. bare.ID, cidaas, Cloud IAM, Engity, Nevis, Quasr, Purse, TrustBuilder and Ubisecure sell on custom quotes only, which usually means a sales call before you can try it.
Open source
Hanko and Ory release their software or models under an open licence, which makes it easier to self-host, inspect what runs, and move again later.
Security certifications
Certifications we have confirmed on the vendor’s own site: Cloud IAM (ISO 27001); Ory (ISO 27001, SOC 2). If your procurement requires one, check the others directly.
What you need to bring from Auth0
List the data, templates and integrations you rely on in Auth0, then confirm each one can be exported and that the alternative can import it or offers an API to rebuild it.
