When VitalPBX is installed by the first time, and you go to the web gui, a form appears to setup the admin password. The form has three fields: username, password, retype password.
By default VitalPBX comes without password, you must to configure it.
I appreciate your prompt response. I am in a situation that my VitalPBX server had a power cycle and is now asking for a username and password. I have tried every way to log back into the server. Not the website. I am wondering if VitalPBX is installed on top of a Linux operating system. So that I can recover the server using GRUB or something of that nature.
