Credentials Added to Microsoft First-party Apps
The question it answers: Which Microsoft first-party service principals have had a secret or certificate added in this tenant?
Microsoft’s own apps (Exchange, SharePoint, Teams and hundreds more) exist in every tenant as service principals. They do not need credentials from you. A secret or authentication certificate added to one lets its holder act as a trusted Microsoft app - the technique Midnight Blizzard used. App Credential Expiry lists credentials by expiry; this report flags the ones on Microsoft-owned apps.
