How to share Wi-Fi password via QR code
How to share Wi-Fi password via QR code. When you go to a place, you ask what the Wi-Fi password is. This is especially true when we find ourselves abroad, where there is no unlimited mobile traffic, to which we are all so accustomed. The same situation occurs if someone comes to visit us and asks for the password from the home Wi-Fi network. There is a very simple way to share even the longest password without having to write it on a piece of paper, enter it on a guest’s smartphone or dictate in the format “es as a dollar and with a dot, ve as a tick …”. The creators of Android have long taken care of us and made it convenient for us. They just forgot to tell us about it. But I will fill this gap and tell everything for them.

How to share a password via a QR code
The easiest way to share anything now is through a QR code. Many countries are even building their economies around it. For example, I told how in China a lot is tied to these small squares . It turns out that they can carry a lot of information, unlike the barcodes that we used before. Now they are relevant only for encrypting a small amount of information. For example, the item number in a supermarket. After all, the cashier receives the article by scanning these stripes before punching the goods.
QR-code translated from English means “quick response code” (Quick Response Code). ”QR code” is a trademark of a type of matrix barcode that was originally developed for the Japanese automotive industry and used in factories to sort parts.
To share a Wi-Fi password on Android , you just need to go to the network settings, select the network you are connected to and click on it. After that, you will see a QR code on the screen with the data necessary to connect to this particular network. This method works on smartphones Huawei, Honor and many others. However, sometimes the algorithm will be slightly different.
For example, on Google Pixel 2XL with Android 10, the QR code does not appear immediately. Instead, an additional menu opens in which you need to click share. Only after that, a QR code will appear on the screen, which must be scanned.
Scanning the code is possible both from an Android smartphone and from an iPhone . At the same time, iOS already from the 11th version (since 2017) allows you to scan QR codes through the standard camera application. You just need to start the camera and point it at the treasured square. A curtain will pop up at the top of the screen, by clicking on which you can go to the page or accept a connection request.
How to scan a QR code with a phone
Unlike modern Apple devices, not all Android smartphones have the ability to scan a QR code out of the box. Someone gives the user a scanner in the form of a pre-installed application, and someone in the form of advanced camera features. But very often the QR scanning application needs to be downloaded separately.
Of course, the easiest way to do this is through Google Play. It is enough just to enter in the search “QR scanner” and choose any of the suggested ones.
Some scanners allow you to save a scan history or have additional features, such as the ability to create your own codes or scan product codes in stores.
How to share a password on iOS
Since we have already talked about how you can share a password, let’s tell you how to do it on iOS.
Apple’s device infrastructure has some very handy features. One of them is the ability to effortlessly share the password from the Wi-Fi network. To do this, you need to have an access point connection on your iPhone or iPad.
If someone comes to you who has not connected to this network, you just need to unlock the smartphone , and the guest select your network and start connecting to it. As soon as he touches her name in the list, you will be prompted to share the password. Sometimes this message may appear within 4-5 seconds, but usually it happens immediately.
After a couple of seconds, the guest will be connected to your network and will be able to use it.
Is it dangerous to use QR codes?
There is only one danger in using QR codes. I do not advise you to scan everything if you do not have confidence in it. For example, a code on the air of a major TV channel or on a movie poster will be safe and is usually purely informational. That is, you will be taken to the site page or to the app store for downloading.
QR codes in leaflets on poles or bus stops can lead to malicious sites or even try to install some software on your smartphone. Such codes are best avoided.
If you use QR codes carefully, this will be an undoubted boon. It is very convenient and simple. It is not for nothing that very large payment systems are built on them in China. That is, in the store it is enough to scan the code and the payment will go through. The Chinese know what they are doing.
