Please can anyone explain what I need to do here, I have my EFIN number , I do not believe I have a PIN number neither does my client, is this something I need to set up or can I just override with any 5 digit number? I get this diagnostic error in ProConnect tax while trying to send EFILE signature request

"Use of the e-file PIN requires the Paid Preparer to have a PIN. The Paid Preparer PIN must be five numbers and not all zeros"
