Introduction
Service Principal Names (SPNs) are critical for enabling applications to authenticate and access resources within Azure Entra ID. Monitoring the expiration dates of SPNs is essential for maintaining security and functionality in your Azure environment. This guide will demonstrate how to check SPN expiration dates using the Azure portal, ensuring the smooth operation of your Azure-based applications and services.
