Introduction
For Beyond Identity's risk-based authentication, we need to carefully balance real-time threat detection accuracy against potential increases in user friction during login. This trade-off involves weighing security enhancements against user experience impacts. I'll analyze this challenge using a structured approach, considering key stakeholders, metrics, and potential outcomes.
I'll start by clarifying the context, then dive into product understanding, hypothesis formation, metrics identification, experiment design, and decision framework before providing a final recommendation.
