GDPR-Compliant Alternative to Firebase Auth
Firebase Auth by Google provides a comprehensive authentication solution for web and mobile apps. It supports various sign-in methods, including email/password, phone, and social logins, ensuring secure user access.
Why You Need a GDPR-Compliant Alternative to Firebase Auth
Since the landmark Schrems II ruling in 2020, transferring personal data to US-based services like Firebase Auth has become a significant legal risk for EU organizations. The US CLOUD Act gives American authorities the power to access data held by US companies, regardless of where that data is physically stored — even if it's in an EU data center.
While the EU-US Data Privacy Framework (DPF) adopted in 2023 provides a new legal basis for transfers, privacy experts and legal scholars have raised concerns about its long-term viability. The framework could face the same fate as its predecessors (Safe Harbor and Privacy Shield), both of which were struck down by the Court of Justice of the EU.
For organizations that want to eliminate compliance risk entirely, switching to a European-based authentication is the most straightforward solution. Below are the best GDPR-compliant alternatives to Firebase Auth, all headquartered in Europe with data stored in EU data centers.

Is Firebase Auth GDPR compliant?
Firebase Auth is a US-based service operated by Google. While it may have some GDPR compliance measures, as a US company it is subject to the CLOUD Act, which allows US authorities to access data stored by US companies regardless of where the data is physically located. This creates a fundamental conflict with GDPR requirements for data protection.
What are the GDPR risks of using Firebase Auth?
The main GDPR risks include: (1) Data transfers to the US may lack adequate protection since the Schrems II ruling invalidated Privacy Shield, (2) US authorities can demand access under the CLOUD Act, (3) Your organization may face GDPR fines up to 4% of annual revenue for non-compliant data transfers, and (4) User consent may not be sufficient to legitimize transfers given the systematic access by US authorities.

How do I migrate from Firebase Auth to a GDPR-compliant alternative?
Most migrations involve three steps: (1) Export your data from Firebase Auth using their data export tools, (2) Create an account with your chosen EU alternative, and (3) Import your data into the new service. We provide detailed migration guides for each alternative to make the switch as smooth as possible.
Can EU companies legally use Firebase Auth?
Since the Schrems II ruling (2020), EU organizations face significant legal risk when using US cloud services like Firebase Auth. While the EU-US Data Privacy Framework (2023) provides a new legal basis, its long-term stability is uncertain. Many EU data protection authorities recommend using EU-based alternatives to avoid compliance risks entirely.
