Credentials are the user accounts that vRealize Operations Manager uses to enable one or more solutions and associated adapters, and to establish communication with the target data sources. The credentials are supplied when you configure each adapter. You can add or modify the credential settings outside the adapter configuration process to accommodate changes to your environment.
For example, if you are modifying credentials to accommodate changes based on your password policy, the adapters configured with these credentials begin using the new user name and password to communicate between vRealize Operations Manager and the target system.
Another use of credential management is to remove misconfigured credentials. If you delete valid credentials that were in active use by an adapter, you disable the communication between the two systems.
If you need to change the configured credential to accommodate changes in your environment, you can edit the credential settings without being required to configure a new adapter instance for the target system. You can edit credential settings by clicking Administration on the menu, and then clicking Credentials.
Any adapter credential you add is shared with other adapter administrators and vRealize Operations Manager collector hosts. Other administrators might use these credentials to configure a new adapter instance or to move an adapter instance to a new host.
