Sorry, I didn't see this question here earlier. No, you don't have to update the password on vCenter. When you add an ESXi host to vCenter, it creates its own local account on the ESXi host with a randomized password. That's one of the reasons why a given ESXi host cannot be managed by multiple vCenter servers; when you add it to a new vCenter server, that server generates a new password for the management account.
