Questions & Answers

As answered by people managing Stack Auth and Engity.

Which are the primary technologies used for building your product?

Engity's answer:

We use Go for the backend and TypeScript with React for the frontend. We also rely on the OpenID Connect protocol and Security Assertion Markup Language (SAML). As algorithm for passwords we use Argon2, AES256 for data encryption and TLS 1.2+ for transport encryption. For signing JSON web tokens, we work with the Elliptic Curves Digital Signature.

How would you describe the primary audience of your product?

Engity's answer:

As a cloud-based IAM provider, our focus is on European SMEs, but also on start-ups as well as grown-ups.

What's the story behind your product?

Engity's answer:

Our founder Gregor spent 15 years to find a smart, easy-to-integrate and legally compliant IAM Software as a Service (SaaS) solution for start-ups, grown-ups and SMEs. With every new employer, he repeatedly scanned the market, but never found the “one” solution desired. . So he decided, it would be worthwhile to develop an industry-agnostic system that would help all his CTO friends who were desperately looking for a suitable solution. With this idea, he contacted his former colleagues and friends Martin, Ursula and Arne to build the one European identity and access management provider for start-ups, grown-ups and SMEs. And to be honest: Companies can also benefit from Engity's feature set and quick and straightforward onboarding process.

Why should a person choose your product over its competitors?

Engity's answer:

As a European Identity & Access Management Provider, we rely on the highest standards in technical data protection. We use cloud data centers in the EU and also the headquarters of Engity is located in the EU. In addition, we not only offer standard authentication functions such as classic login with password and username, or password-free login using Magic-Link or biometrics, we also develop authentication functions specifically at the customer's request.
