When deploying 3CX through the installer, administrator credentials are sent to the email address provided during license activation during deployment of the 3CX communication system. If you deploy 3CX through the Customer Portal, your credentials will only appear once at the end of the process. 3CX does not have access to your credentials. However, if you lose your credentials, you can recover them by following the instructions. You can also restore your credentials from a backup. As a last resort, open a support ticket. We will support you.
