To add an already existing hosting account to the list of accounts in your Account Panel, you need its main domain name and the hosting Control Panel login credentials (username and password). You can claim hosting accounts by going to the "Hosting Resources" > "Hosting Аccounts" section, and following the "Claim Account" link.

On the next page, you need to enter the domain name of the account, its hosting username and password, as well as associate a new or existing Client with the account. Please refer to the Client Management help section for additional information.
