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.
