For secure vRealize Operations operation, you might need to perform maintenance on authentication certificates.
Authentication certificates are for a secure machine-to-machine communication within vRealize Operations itself or between vRealize Operations and other systems.
By default, vRealize Operations includes its own authentication certificates. The default certificates cause the browser to display a warning when you connect to the vRealize Operations user interface.
Your site security policies might require that you use another certificate, or you might want to avoid the warnings caused by the default certificates. In either case, vRealize Operations supports the use of your own custom certificate. You can upload your custom certificate during the initial primary node configuration or later.
