From the left navigation menu, select the Hosts page, and then select the Host Credentials tile.
On the far right of the Credentials grid, click Add Credential to open the dropdown menu. Next, select Create Credential. Create credentials for each of your hosts. For demo purposes, it may be useful to manage one set of credentials replicated on each machine.
