QGroundControl Customization

Hello, I’m attempting to add a login page to my QGC but have no idea where to begin or what to do. Could someone please assist me?

I am doing the same thing (customising qgc), and I hired a third party contractor because my customised version is only going to be used by (and of benefit to) myself, so unless your modifications can benefit all users, or are relevant to all users then you cannot expect someone to work on your project for free, can you? Just saying

Sharing is the spirit of Free Open Source Software. If you add support for any hardware or services that are available to the public it is in good taste to share. If somebody before you didn’t decide to share their work you would be stuck with proprietary closed source software you can’t modify.

I would look at Youtube tutorials for adding Google Firebase Auth to Qt Applications. That’s how I did it.
