How do I change an account username of a contact person?
Username change is not supported in Openprovider ecosystem due to the backward compatibility between its various systems (RCP, SSL Panel, Single DNS Panel, etc).
This policy also applies to the allowed number of admin contacts in ones reseller account. There can only exist one admin account and its username cannot be changed.
The emailaddress of an Admin contact can be adjusted, but the username of the Admin contact itself can not be changed.
