Which feature is available for Premier Plus customers when opening a case?

The feature available for Premier Plus customers when opening a case is the dedicated support phone number. This service provides Premier Plus customers with immediate access to support professionals who can help with urgent issues or complex inquiries. Having a dedicated support line allows these customers to resolve issues quickly and efficiently, enhancing their overall experience with Okta's services. This is especially important for businesses that rely heavily on Okta's functionality for security and identity management, as timely support can play a crucial role in maintaining operations and preventing disruptions.

The other features mentioned, like access to community forums, free technical training, and extended documentation access, may be available to different tiers of customers or as part of other offerings, but they do not provide the same level of personalized and immediate assistance that a dedicated support phone number offers. This distinction makes the dedicated support phone line a significant benefit exclusive to Premier Plus customers.
