You may findto do this on Android phones, but you may need to enter the credentials as part of the setup. In Android Q, just tap a button in your Wi-Fi settings to generate a share code. To scan, just open your iPhone or Android camera app and scan the code automatically. It is based on the Wi-Fi Easy Connect standard of the Wi-Fi Alliance to share network permissions with a QR code.
lets you add devices to the Wi-Fi network that you manage using a QR code on a sticker or devices that you scan using your Android Camera app – including Smart Home and Internet of Things devices. The device must support the Easy Connect Wi-Fi standard for this to work.
Creating a QR code for a Wi-Fi network
Android Q shows you how to share your Wi-Fi credentials with a QR code.
Go to Settings, Network & Internet, then the name of your Wi-Fi network and tap the gear to the right of your network.
In the Network Details window, tap the blue Share button on the right.
Enter your passcode to generate a QR code with the Wi-Fi name and password.
There seems to be no way to save the QR code. Therefore, you must recreate it each time you use it.
To scan a QR code to connect to a network
On Android, you can choose "Add Network" at the bottom of the Wi-Fi settings to scan a QR code. What is simpler, however, is that the camera app can scan QR codes as soon as you turn on the lens.
Open the camera app from Android.
If you have not used Lens yet, tap More in the camera settings that run across the ground.
Tap "Lens," then tap "Turn on Camera" to use the lens.
Now position the camera viewfinder over the QR code and tap the code.
If the name of the network appears below the QR code, tap it to enter the Wi-Fi network.
On an iPhone ($ 1,000 on Amazon) and iPad ($ 280 on Amazon) with iOS 11 it's even easier:
Open the iOS Camera App.
Position the camera app's viewfinder over the QR code. When the camera detects the QR code, a notification is displayed.
Tap the notification to connect to the Wi-Fi network.
On iPhone or Android, after tapping on the Wi-Fi network notification, you can not enter a password.
