Measuring authentication effectiveness involves tracking several key performance indicators (KPIs) to assess both security and user experience. Crucial metrics include the authentication success rate, calculated as successful logins versus total attempts, and inversely, analyzing failure rates and their root causes, such as incorrect credentials or system errors. We also monitor authentication latency to ensure quick response times, alongside system throughput to gauge the capacity for handling concurrent requests. For robust security, it is vital to track Multi-Factor Authentication (MFA) adoption and completion rates among users. Furthermore, ongoing monitoring of suspicious login attempts and related security incidents provides critical insights into potential threats like credential stuffing or account takeovers. These metrics collectively offer a comprehensive view of the authentication system's performance, reliability, and security posture.
