Windows 10: Link to Windows - QR Code / Pin

I'm hoping people out there smarter than me have a solution.I have the Your Phone Companion App on my Windows 10 machine and The Link to Windows on my Samsung Galaxy S21 Ultra, is built into it.When I go to the PC - it generates a QR code for me to scan...When I go to the phone - it wants a PIN and not a QR code and tells me to close the QR screen on my PC and follow the instructions to create a pin.The problem - no such instructions exists on the PC - I cannot see how to close the QR code & create a pin. Simply closing the QR code window doesn't achieve anything.

QR Code Question

I'm working on completely rebranding the company I work for. Everything from the website, trucks, business cards to the shipping boxes. I am basically creating a new brand from the ground up.

I've done this before but I have never used a QR code. My question is I see a lot of QR code generators online that are free. However when I type in the same exact web address I notice the pattern in the code is different from site to site and day to day but, the code I generated last week seems to work fine.

Do QR codes expire and is there a way to pay for one so that a year from now the QR codes on the sides of our trucks don't lead people to some strange porn site or something?

 

QR Code Question

I'm a little late to this but QR codes are static. They're like barcodes but contain a lot more binary. If you don't get the same values from the same QR code, either the code itself has degraded (e.g. smidges making areas that should be white a shade of dark gray or black) or the software used to process it isn't working. Here's a basic breakdown of what each part of the QR code is about:



And if you want to learn more about them, see Wikipedia. The only way a well-formed QR code could point to a porn site is if you use an URL-shortening service (e.g. bit.ly) and that URL it generated gets repurposed to point to a porn site. To avoid that problem, simply don't use an URL-shortening service.

 

QR Code Question

There are varying levels of error correction and it's possible that the exact same data can be encoded in different ways by different generators. They all try to create the most readable pattern.

The one Mindweaver linked is legit, checked with a QR Code screen reader.
