Microsoft Graph List signIns
Retrieve the Microsoft Entra user sign-ins for your tenant. Sign-ins that are interactive in nature (where a username/password is passed as part of auth token) and successful federated sign-ins are currently included in the sign-in logs. The maximum and default page size is 1,000 objects and by default, the most recent sign-ins are returned first. Only sign-in events that occurred within the Microsoft Entra ID default retention period are available.
