AADManagedIdentitySignInLogs

Managed Identity Sign-In Logs Overview

Managed identities in Azure are a feature that provides Azure services with an automatically managed identity in Entra ID. This identity can be used to authenticate to any service that supports Entra ID authentication, without needing to manage any credentials, secrets, or keys manually. This table keeps a record of the sign-in of these identities.
