LoginEvent

LoginEvent is an event emitted by an authentication or identity service to record an attempt to sign in. It is used for security monitoring, auditing, and compliance. A LoginEvent captures the essential data about a login attempt and its outcome, enabling operators to track user activity, detect anomalies, and investigate incidents.

Typical fields include: event_id, timestamp (UTC), user_id or username, success (true/false), method (password, MFA, biometric, token), ip_address, device_id, location or geo_location, session_id, application, tenant_id, and optional fields such as reason, error_code, and user_agent. Some implementations also record MFA_used and push_notification_id.

Types and variants: successful logins, failed attempts, and throttled attempts. Additional variants may include passive sign-in events, password changes triggered by login, or SSO-based sign-ins. The event may be generated by identity providers, applications, or security gateways and may be correlated with other events such as password-change or account-lock events.

Uses: Security monitoring and incident response; auditing and compliance reporting; user behavior analytics and authentication analytics; access governance and risk scoring. In practice LoginEvent data is ingested by SIEM systems, log aggregators, and identity and access management (IAM) tools to enable searches, alerts, and dashboards.

Privacy and retention: Organizations should minimize data collected, apply access controls, encrypt data in transit and at rest, and define retention policies aligned with policy and regulation. Personal data such as IP addresses and geolocation may be restricted or pseudonymized for analytics. PII handling must comply with applicable privacy laws.

Implementation notes: Treat LoginEvent as a structured log with a stable schema; use a unique event_id; prefer UTC timestamps; standardize field names; include correlation_id to link related events; store in machine-readable formats such as JSON; design for scalable querying and cross-system correlation.
