No more looking for the scrap of paper with your Wi-Fi password. And no more mistyping the password. In Android Q from Google, you’ll be able to generate a QR code with the credentials to your Wi-Fi network that guests can scan with their phone’s camera to log on.
You could find third-party apps to do this in Android phones, but it required a bit of setup. In Android Q, you just tap a button to generate a code to share. And it’s based on the Wi-Fi Alliance’s Wi-Fi Easy Connect standard for sharing network credentials with a QR code.
