Have you ever encountered a situation where your friends come over to your place and ask for your Wi-Fi password to connect to your Internet? There are times when sharing your Wi-Fi password is not possible, either because it is too long and you can’t remember it, or you are afraid they will spread your password around and make your Wi-Fi network vulnerable to hackers. Fortunately, Android offers a way to use a scannable QR code image to share your Wi-Fi.
Generating the QR Code
For this to work, your Android phone has to be connected to the Wi-Fi network. Turn on your Android phone and go to the Settings menu.
Note: the following steps will differ from phone to phone, but the QR code sharing option will be there unless you are using a really old Android phone.
Scroll down the list of options relating to the functioning of your phone until you see the Network & Internet option. Click on this option to open a new page of functions.
Click on Wi-Fi. You will see the name of the Wi-Fi network that you are currently using on the new page.
Next to the name of your Wi-Fi network is a gear icon. Press it to go to its Settings page.
Tap on the blue Share button. In the new window that pops up, enter your password code to verify that you are the owner of the phone.
A QR code will appear onscreen.
On your friend’s Android phone, go to Settings, then “Network and Settings,” and open the list of Wi-Fi networks that are available.
Scroll down the list until you see the “Add Network” option, and tap on the blue QR code icon next to it.
Aim the phone at your QR code, and it will connect your Wi-Fi network.
If you have a habit of sharing your Wi-Fi connection with others, you should also frequently scan for devices on your Wi-Fi network to make sure that no unauthorized devices are lurking around.
