You should find the link and username and password for your control panel in the welcome email that we sent you when you opened your account.
Typically web hosting customers can access their control panel using: http://www.domain.com/cpanel, replacing domain.com with your domain.
If you need your welcome email re-sent, please ask the Support Team to do so. You may also reset your password to your cPanel account via www.dowo.digital/clients.
