Which plugin must be activated for using External Storage Credentials?

The External Credential Storage Plugin must be activated to utilize External Storage Credentials effectively within ServiceNow. This plugin facilitates the management and storage of sensitive credentials in an external storage system, allowing for secure retrieval and usage during various processes, including Discovery.

By enabling this plugin, users can integrate external credential management options seamlessly with ServiceNow, ensuring that credentials are not only stored securely but also accessed in a manner that complies with organizational security policies. This capability is particularly important when dealing with multiple cloud providers or third-party services where secure credential management is critical for effective and secure operations.

In the context of the other options, while plugins related to discovery and cloud credentials may be relevant to specific functionalities within ServiceNow, they do not specifically cater to the management and storage of external storage credentials as required for this particular function. The focus on the External Credential Storage Plugin uniquely positions it as essential for securing sensitive information needed during automated processes.
