How to generate a QR code with the Wi-Fi password on a Samsung Galaxy A40

If you want to share the password or key of the network your Samsung Galaxy A40 is connected to, and quickly set it up on another Android device (whether it's a Samsung or another brand), this tutorial will show you how. We'll guide you on using the native method included in Android 10 and later versions to generate a QR code with the Wi-Fi password.

The Samsung Galaxy A40 comes with Android 9.0 out of the box, though it may have received updates over time.

Once you generate the QR code on your Galaxy A40, you can scan it with the camera of the other device or download it as an image. This way, you can reuse the code whenever you need without repeating these steps.

Estimated time: 2 minutes.

1- First step:

First of all we must make sure that we are connected to the Wi-Fi network that we want to share from our Samsung, if so we access the settings of the Galaxy A40, it is the icon of a gear wheel. If you do not see it on the Samsung Galaxy A40 home screen, swipe up from the bottom of the screen and you will see it.
