Login audit log

Track user sign-in activity

You can use the Login audit log to track user sign-ins to your domain. You can review all sign-ins from web browsers. If a user signs in from an email client or a non-browser application, you can only review reports of suspicious attempts.

Forward log event data to the Google Cloud Platform

You can opt in to share the log event data with Google Cloud Platform. If you turn on sharing, data is forwarded to Cloud Logging, where you can query and view your logs, and control how you route and store your logs.
