Wow, this is finally a thing? Yes it is, in Android and iOS, you can read a Wi-Fi pasword via a QR code. This allows you to use much longer and randomly generaed Wi-Fi passwords with ease. Unfortunately, there’s still not a way to do this with laptops… but presumably it’s not as necessary there since you can plugin to the wired network easier, correct?
Here’s how to both generate the QR code and to read it.
