Reading Authentication Logs Like an Analyst

PLACEHOLDER — replace with the post body from the Wix technicalblogposts collection. Authentication telemetry answers three questions in order: where did this identity authenticate from, what changed about how it authenticates, and what did it reach afterwards. Analysts who start with the third question spend hours in the wrong place. Baseline first, then deviation. An impossible-travel alert on an account that has always been geographically noisy is a different investigation from the same alert on an account that has used one office IP for two years.
