Is Auth0 compliant with the GDPR?

Auth0 is a US provider that offers one of the leading identity and access management solutions as a cloud service. In addition to Amazon Web Services, Auth0 also uses other US cloud services such as Cloudflare, Twilio and Sendgrid. This may result in personal data being processed on servers in the USA. With cidaas, the personal data remains within the EU and is not transferred to the USA. The USA is considered an unsafe third country according to a decision of the European Court of Justice. cidaas as a leading European cloud identity & access management provider, with exclusively European cloud infrastructure, and Auth0 as a US-American provider thus differ especially in the area of data protection and GDPR.

Why is cidaas the best Auth0 alternative?

In addition to the topic of data protection and GDPR, the time-to-market is another important factor with which cidaas convinces as the best alternative to Auth0. This is especially due to the fact that with the cidaas platform and the significantly larger range of functions, existing and also new requirements and ideas can be implemented quickly and easily. Thus, required functions do not have to be developed first or integrated via other products, but can be used directly from the cidaas platform. This gives cidaas customers a significant time advantage over Auth0, which is not only reflected in financial added value, but also provides a significant innovation advantage, which is ultimately also reflected in the company’s image as an innovative company.

Why do I need an alternative to Auth0?

With a German or European provider, such as cidaas, strict industry-specific regulations and the guidelines of the GDPR can be easily implemented. Customers of cidaas benefit not only from German and European infrastructure, but also from German law and local contacts. The feature-complete platform also impresses with a comprehensive range of functions with which customers can implement many requirements out-of-the-box.

Customer voices

What our customers say

Since we’re a bank that also works with health data, our location in Germany is a very, very important asset that we’ve now linked with cidaas, and that was the deciding factor.

mediserv Bank GmbH

Read the success story

On the path to uniform customer identity and access management for the Schwarz Group, cidaas has proven itself to be a trustworthy and competent partner. The switch from open source to cidaas enabled us to connect end customer touchpoints even faster and more flexibly and to create a uniform customer experience. Further joint steps are planned, for which we are counting on the expertise of cidaas.

In the end, of course, another deciding factor was that we could work with a German company that hosts its services in Germany. Choosing cidaas also meant a certain degree of security, including location-based security. It’s quite clear that, basically, the only other providers are overseas – so that’s a very clear point that cidaas makes here – and accordingly, I would at least recommend that everyone consider checking it out.

Why European enterprises choose cidaas

Identity & Access Management is a critical building block of enterprise security. European organizations face unique challenges: strict data protection requirements under GDPR and industry-specific regulations, the need for digital sovereignty, and demand for local support and expertise.

Auth0, part of Okta since 2021, is one of the world's best-known identity platforms. However, since the acquisition, many companies and developers report increasing challenges: unpredictable price escalation driven by the MAU-based pricing model (industry experts call it a "growth penalty"), feature gating of essential capabilities behind expensive enterprise plans, and declining support quality. As a US-based provider, Auth0 also relies on US services that process personal data on servers in the United States.

cidaas addresses exactly these challenges: as the leading European Cloud IAM platform - designed, operated, and hosted exclusively within the EU - cidaas offers a feature-complete platform with transparent pricing and personal support.

Why act now

3 compelling reasons

Regulation is tightening. DORA applies to financial entities since January 2025, NIS2 is being enforced across EU member states. European organizations need identity infrastructure that meets these requirements now.

Pricing can be hard to predict. Since the acquisition, Auth0's pricing has changed several times, which can make long-term budgeting more challenging.

Digitale Sovereignty matters. Reducing dependency on US-jurisdiction providers is no longer optional for many regulated and public-sector organizations in the DACH region and EU.

FAQs: Auth0 alternative

Everything you need to know about Auth0, switching to cidaas, the best European Auth0 Alternative.

As a US-headquartered provider, Auth0 (part of Okta) is subject to US jurisdiction including the CLOUD Act, under which it may be compelled to disclose data in its control regardless of where that data is stored. Auth0 also relies on a number of US sub-processors, which can result in personal data being processed under US jurisdiction. cidaas, as a European alternative, is a German company and hosts on sovereign EU cloud infrastructure.

The most common reasons for switching are: unpredictable price escalation under Auth0's MAU-based model (which industry observers have called a "growth penalty"); key capabilities being available only on higher or enterprise plans; concerns about data sovereignty and US jurisdiction; and the demand for local support in German and English during European business hours. cidaas offers transparent pricing with core capabilities included, a broad feature set, and full European data sovereignty.

The migration from Auth0 to cidaas involves three steps: (1) Setting up the cidaas environment and configuration, (2) Migrating user data including password hashes, and (3) Reconfiguring the applications. Thanks to open standards (OAuth2, OpenID Connect) and proven migration tools, the switch can be completed in a few weeks. During migration, both systems run in parallel so your end users are never affected.

Yes. cidaas supports the migration of password hashes from Auth0. Request a complete user export including password hashes from Auth0 support. The cidaas migration tools import this data so your users can continue to log in with their existing credentials - no password reset needed.

Auth0 offers limited in-built consent management. For comprehensive, GDPR-compliant consent handling, additional configuration or external solutions are typically required. cidaas, by contrast, provides fully integrated consent management where users can transparently view and manage their consent preferences — an essential building block for GDPR compliance.

Yes. cidaas is built for complex B2B scenarios. Beyond simple tenant isolation, cidaas lets you organize users into groups that can be typed with their own roles and restrictions - with delegated administration, hierarchies, and custom group-level attributes. This models real B2B structures such as partners, subsidiaries and customer organizations, as well as B2C models like Family & Friends, all without custom code. Combined with fine-grained authorization (RBAC, ABAC, ReBAC, PBAC) and enterprise SSO, cidaas supports B2B, B2C and B2B2C from a single platform.

Auth0 was acquired by Okta in 2021, and its pricing model has changed repeatedly since. With the pricing update effective November 2023, the B2C Essentials plan’s included allowance was cut from 1,000 to 500 monthly active users while the entry price rose from $23 to $35 per month, and the per-MAU overage rate roughly tripled - from $0.023 to $0.07. For organizations that need stability, planning certainty, and personal support, cidaas - as an owner-managed European company - offers a reliable alternative.

cidaas is the only European CIAM platform that combines full GDPR compliance with a comprehensive feature set, transparent pricing, and personal support in German. As Overall Leader, Product Leader, and Innovation Leader in the KuppingerCole Leadership Compass 2026, cidaas is recognized by independent analysts as one of the world's leading CIAM solutions. With customers like Europa-Park, HORNBACH, and Takko, cidaas is the proven European alternative to Auth0.
