In case there are no working credentials for a device, which credentials are utilized?

When there are no working credentials for a device during a ServiceNow Discovery process, the system will utilize the MID Server service account. The MID Server is a critical component in ServiceNow that handles the communication between the ServiceNow platform and the environment being discovered. This service account is configured to run the MID Server and can possess the necessary permissions to access devices in the network.

Using the MID Server service account essentially allows the Discovery process to proceed even when specific device-level credentials are unavailable. It acts as a fallback mechanism to ensure that the discovery can continue, enabling the retrieval of data even without individual device credentials, which might not be available or configured correctly for every device.

In other scenarios, the default device credentials, user account credentials, or previously stored credentials may also be options, but they are not the primary choice when the MID Server service account is set to handle such situations. Thus, in cases lacking specific credentials, relying on the MID Server service account ensures continuity and effectiveness in the discovery process.
