Android Q finally allows easy sharing of Wi-Fi passwords as QR code or simply text


We’ve all been there, asking our party host for the Wi-fi password, so that we can keep our mobile data to ourselves. They had to take it out from memory, track it written down somewhere, or, exasperated, turn over the router so that you can key in those twenty random digits yourself. 
If they had a phone whose Android overlay allowed the password to be rendered as a QR code, like most Chinese brands, and if your camera or third-party app could scan it, then sharing said password became inherently easier.
