How to Share the Wifi Key through a QR Code

QR codes have become very popular because they work as a quick payment option when making transactions with digital wallets. In this case, it is enough to scan the QR code of the business with the payment application, enter the amount to be paid and confirm the operation. All this without any kind of contact. There are even many situations in which the QR code generated on the sales terminal screen already contains the amount to be paid.

Under a similar concept, the function to share the access password to the router is executed on an Android phone, as long as the connection is established at that moment. In this case, a QR code is generated from the Android device that will share the password, so that when it is read by another iPhone or Android phone, the connection is made automatically.

This function is useful in various occasions. For example, when the password is made up of complex characters that are difficult to memorize, you do not want to reveal it, or for any other security reason. We show you how to use it.

How to connect to wifi using a QR code?

From your Android phone, go to Settings > Wi-Fi and tap on the Wi-Fi network the phone is connected to.

When the QR code appears on the screen, have it scanned with the camera of the other phone or tablet that you want to connect and click on the option to access the network, usually written in yellow letters.
