Why this catalog

When designing a login flow, account recovery process, or data deletion feature, best practices do exist, but they are often scattered. They can be found in isolated articles, discussion threads, and field experience reports.

Product Security UX brings these topics together in one place. Each article starts from a real-world problem and provides recommendations, along with their sources.

The goal is to examine security from the user's perspective, without treating protection and user experience as opposing forces.
