Describe how to configure devices with a Central QR code and other settings

Scan the Central QR code into Collect, then update settings as needed, then use that device's QR code to configure others.

This works if the App User is role-based only (as opposed to representing a specific person).

From support I have given:

* Reset Collect completely from Admin Settings > Reset application…
* Scan in the App User QR code to add configuration to
* Configure the device exactly as desired

You can then configure all other devices that need the same App User credentials by scanning the code directly from the phone or if you need to share the QR code in some other way (print it, put it on a slide, etc), from Admin Settings > Configure via QR code, use the Share button at the top right to share the resulting QR code image. I typically send the code to my computer and use an image editor to add the project name and App User name to the image.

I typically don’t set an admin password unless the field staff is really untrustworthy or curious and liable to get confused.

Start by locating the existing documentation for Collect device setup and Admin Settings. Compare it with the reported Central QR-code workflow, including role-based App Users and sharing the generated image. Done means the reset, scan, configuration, and sharing steps are clear and accurately cover the stated admin-password caveat.
