Have a user authentication and login system built
Secure login, registration, role management, and access control. Built with Zitadel — self-hosted, OIDC-compliant, and enterprise-grade.
Authentication is one of those components you don’t compromise on. Poor implementation means security breaches, data leaks, and loss of trust. We build authentication with Zitadel — self-hosted, OIDC-compliant, and enterprise-grade.
From simple login and registration to complex role-based access control in multi-tenant applications: we build it right, the first time.
Authentication that handles the edge cases
Logging in sounds simple. But once you need role-based access, multi-tenant architecture, SSO via an existing identity provider or just a system that runs GDPR-compliant in Europe — it gets complex. And complex authentication done incorrectly is a security risk.
We implement authentication via Zitadel: open-source, self-hosted on our European servers, OIDC-compliant, and enterprise-grade. No Firebase Auth with data in the US. No Auth0 with a monthly bill that grows with your user count.
What we set up
User registration and login flows. Role-based access control (RBAC) — the right people see the right things. Multi-tenant isolation for applications with multiple organizations. Password recovery, email verification, session management. And if desired: SSO via Google, Microsoft, or another identity provider.
This is how we work
No surprises, no vague promises. Just action.
