Starting with Android 10, phones running Google’s mobile OS can share Wi-Fi passwords between handsets using a QR code. All the recipient has to do is open the default camera app on their iPhone or Android device to scan the code and instantly connect to the Wi-Fi network.
When you’re ready to grant access to your Wi-Fi network, navigating to your handset’s Settings menu. The easiest way to do this is by swiping down from the top of the device’s screen to show the Quick Settings menu. From there, tap on the Gear icon to open the Settings menu.
As each Android smartphone is slightly different, you might need to swipe down a second time to locate the Gear icon.
Alternatively, you can swipe up from the bottom edge of your phone to access the App Drawer. Here, you can locate and open the “Settings” app.
Next, select the “Connections,” “Network & Internet,” or similar option. Again, this menu name might differ depending on the manufacture of your Android handset.
Now, tap on the “Wi-Fi” listing from the top of the menu.
Make sure that you’re connected to the Wi-Fi network that you want to share with others and then either select the network name (SSID) or the corresponding Gear icon.
You’re now in the Advanced Settings menu for the given network. Tap on the “QR Code” or “Share” button. No matter what your smartphone calls the button, it should be represented with a QR code icon.
Note: Some OEMs might require you to input your screen lock password/PIN/pattern/biometrics before it displays a code.
Your Android handset will now generate and show a QR code. Have your guests open the default camera app on their Android smartphone or iPhone and scan the code. A message might pop up, asking if they want to connect to the Wi-Fi network.
Devices that are running Android 10 and later also have an option within the phone’s Wi-Fi Settings menu to scan a QR code.
