No device comes off the shelf with OpenWRT. If you're the type of person that's aware of OpenWRT and then install it, it's not that far of a stretch to think you'd also be the type to know to check the password.
GL-inet devices come off the shelf with OpenWRT. They don't have a blank password. Every single one ships with 'goodlife' as the default password, as printed on the label on the back.
I am only thinking of a router with OpenWRT installed. Nothing about a wifi router with OpenWRT has anything to do with a door access device installed by a trained technician or not. The conversation only pertains to the words used, not the unwritten ones you're trying to insert in between the lines of my comment to make a totally unrelated point
