CircleCI audit logs track actions like creating contexts and triggering workflows, but don't capture user login events. This creates a gap for security teams who need to monitor all platform access. Problem: * Can't track users who log in but don't trigger builds * No way to see who accessed CircleCI during a given period * Current "Active Users" only shows users who trigger work * Missing visibility into authentication patterns and potential security incidents Requested Events: user.logged_in - Successful authentication Use Case: Enable security teams to monitor all platform access, track login patterns, and automate access reviews via audit logs and API.
