Shared application online for Android access needs safety measure

Applications made with Qt Design Studio can be shared online. With the Qt UI Viewer Android app, it has become easier just to scan a QR code and get all the projects from a particular user. However, this has also brought in some safety issues. Now if anyone can manage to get an image of the QR code of a user, they can quickly grab all the projects. This should not be allowed without the user's consent.

In terms of more prominent and critical projects, a significant issue can arise if a design gets leaked without the knowledge of the technical artist. Since it is easy to make a picture of the QR code and bring it to scan in Android immediately, the problem is genuine. 

I suggest having a validation on the Qt Design Studio end. So, if the QR code gets scanned, it would require consent from the creators. Otherwise, the connection would fail, and nothing would get transferred to the Android system.
