About Authentication Test

Authentication Test provides a simple, reliable way for developers, security engineers, and automation teams to test login workflows against realistic authentication scenarios.

Whether you're building automated login scripts, validating integrations, or demonstrating authentication behavior, this site gives you a controlled environment with known-good configurations.

Once authenticated, the interface reflects a successful login state (top-right shows “Log out”), making it easy to validate automation without unnecessary complexity (e.g., no XSRF token on logout).

The platform includes a variety of challenges designed to simulate real-world authentication patterns, including:


These scenarios help developers understand how authentication systems behave—and how automation should adapt to them.

Authentication Test is also useful for:


This project was built from real-world experience working with authentication systems, with the goal of providing a practical, no-friction environment for testing and learning.

About the Author

Hi, I’m Robert Lerner. I work in application security and spend a lot of time dealing with authentication systems, edge cases, and the weird ways things break.

I built Authentication Test as a practical playground for developers and security engineers to test login automation, explore real-world auth challenges, and demonstrate how systems behave under different conditions.

If you’ve ever had to script around CSRF tokens, MFA, or session handling—this site is for you.
