Simple authentication hosted in Europe

Say goodbye to endless config files, surprise pricing, and compliance headaches. Our authentication service makes it easy to secure your app and manage your users. Whether you're just launching, or scaling to millions.

Modern. Pre-configured. Hosted in Europe.

Authentication, just a redirect away.

We keep things simple by skipping outdated login methods that are clunky or insecure. Instead, we focus on today’s best practices. That means less surface area for attackers, faster integration for your team, and a login experience your users will actually like.
