To access the Onebox panel you need to have a CPanel access user. Your CSM will be in charge of registering it.
Contact us and, once you have the access data, you will be able to access the control panel via web from this url: cpanel.oneboxtm.com/admin.
Please note that, depending on the permissions you have been assigned, you will have access to certain contents in the CPanel. Only the administrator of the entity can access all the contents of the platform.
