FusionAuth is the authentication and authorization platform engineered for developers who demand flexibility and control. Built from the ground up to integrate with any stack, every feature — from user registration to MFA and SSO — is exposed via a modern, well-documented API.
Support for every major identity protocol is included out of the box: OIDC, SAML, OAuth2, JWT, passwordless login, social sign-on, and more. Whether you’re building a greenfield app or retrofitting auth into a legacy system, FusionAuth adapts to your use case — not the other way around.
Need compliance? FusionAuth helps you meet GDPR, HIPAA, and COPPA standards quickly and reliably.
Deploy it your way: install on Linux, Windows, macOS, Docker, or Kubernetes — or go with FusionAuth Cloud, our managed SaaS hosting. No black boxes. No vendor lock-in. Just powerful, customizable auth that works the way you do.

Most identity verification stacks were built around document scans and selfies. Authologic starts from national eIDs instead.
The platform gives regulated businesses one API for every major verification method: national eID schemes, government identity wallets, bank IDs, government registry lookups, document OCR and biometrics. Each market gets the method its users already trust, without a separate integration for every country.
Coverage runs to 100+ verification methods in 240 countries and territories. Routing, fallback and workflow logic are automated, so entering a new market is a configuration change rather than an onboarding rebuild.
Fintech, banking, gaming, telecom and e-commerce teams use Authologic to lift conversion, cut fraud losses and satisfy KYC, KYB and AML obligations under one workflow.
Compliance credentials: eIDAS 2.0-ready, PSD2 AISP-licensed, ISO 27001, ISO 9001 and ISO 22301 certified. Y Combinator alumni, Series A backed, with teams in London, San Francisco and Warsaw.
