Check Service Usage in Event Log > Learn how to view service access history using the event log. #### Checking Service Access Status The following methods are available to check service access logs. 1. **Access status via Google login**. If you have integrated Google Workspace, you can view access status for services accessed using Google login. See [Shadow IT Detection via Google Workspace (Details)](/en/it-management/shadow-it/8nwq5urwh5-shadow-it) for more information. 2. **Access status via Microsoft 365 / Microsoft Entra ID**. This requires integrating Microsoft 365 / Microsoft Entra ID using an account with an Entra ID Premium P1/P2 license. Once integrated, you can view access history for services accessed through Microsoft 365 / Microsoft Entra ID login. 3. **Access status via browser extension** You can view access status from browsers with the extension installed. For details, see [Distribute the Browser Extension to Detect Shadow IT](/en/it-management/shadow-it/7q1wryx3dk-extension). #### Viewing the Event Log Navigate to **Integration** > **Event Log**. You can filter by service name or email address.
