Share passwords Wi-Fi It's one of those annoying things about modern life. Even with a separate guest network set up on your router, you still have to share some kind of indiscreet information with visitors to your home.
And that usually means spelling out some meaningless numbers and letters. And of course, they will probably misspell it at least twice. So the next step is to write the password down on paper or send it in a message on WhatsApp.
However, with Android 10, there is a much easier, faster and simpler way to share your Wi-Fi password, without the need for boring password conversations and, better yet, without having to give out the password.
How to easily share your Wi-Fi with your visitors
First, be aware that both you and your friend need to have devices running at least Android 10. With that in mind, you can head over to your Wi-Fi settings to get started.
Swipe down your Android notification bar. Then, tap and hold on your network name. A screen similar to the image below will appear. Now, near the top, you should see an icon that indicates a QR code.

Depending on the model and manufacturer of your phone, the icon may be located in a different location. But the important thing is to find this QR code icon to share your Wi-Fi. If your phone is running Android 10, this icon will be present, don't worry. When you click on this icon, the system will generate the QR code and display the screen below:

The next step is up to your visitor. They will access the list of Wi-Fi networks and find the “Add network” option. However, instead of going directly to the network, they will click on the QR-Code icon, as shown in the screen below. This is how you share Wi-Fi without a password.

After clicking, the screen to read the QR-Code on your cell phone will appear, as shown in the figure below.

Your guest points the camera at their cell phone with the QR code and that's it: the connection to the Wi-Fi is made without having to enter the password.
All he has to do is point the camera at your QR-Code and that's it. You've just shared your Wi-Fi without revealing the password.
