Pavel Jelic In my opinion, the majority of the Czech and Slovak population has WiFi at home. Sometimes an unpleasant situation can arise when a visitor comes to your house and asks you for the WiFi password. As we all know, dictating a password is not very good. So why can't we just give the visitor a QR code that they can scan with their camera and connect automatically? Or, for example, do you own a restaurant and do not want to write a password on the menu so that it does not spread to the public? Create a QR code and print it on the menu. How simple, right?

How to create a QR code
- Let's start by opening a website qifi.org
- To create a QR code we need to know some information about the network – SSID (name), password a encryption
- As soon as we have this information, it is enough to gradually put it on the website fill in the boxes intended for that
- We check the data and press the blue button Generate!
- A QR code is created - we can, for example, save it to the computer and print it
If you have successfully created a QR code, then congratulations. Now all you have to do is connect using the QR code on your iOS device:
- Let's open Camera
- Point the device at the created QR code
- A notification will appear Join the network "Name"
- Click the button on the notification Connect confirm that we want to connect to WiFi
- After a while, our device will connect, which we can verify in Settings

That's it, it's that simple to create your own QR code to connect to a WiFi network. If you own a business and your password has often become public, this simple procedure will easily get rid of this inconvenience once and for all.
Would anyone really give their password to a site that is protected by a Lets Encrypt certificate?
May I ask what is wrong with Lets Encrypt certificate protection? I don't mean it ironically, I'm just curious because I use Lets Encrypt myself.
It's just that anyone can generate it. If it is a normal page or a company page where I create an account, there is no problem, but as soon as I have to enter my password or payment information on such a page, I become smarter and better go away...
You generate the code and pray that the service does not collect your information (including password) and does not share it with anybody…
Are you kidding yourself, I'd almost say shameless solicitation of information, can't anyone take this seriously? , that I will send information to the web server, how anyone can attack me and I don't even know who is behind that page, who reads it, who sells it to whom, who steals it when... ? But there will certainly be quite a few people who will enter it... The editors should think about whether this is not a "deceptive act"... it should rather have been communicated that BEWARE RISK, here if you generate a QR code you like, expect that you can be attacked by anyone who gets hold of the information from the server I send it to.
Note that the site doesn't communicate with the internet at all, so it's perfectly fine to put your password there, it won't get anywhere. Whoever gets hold of the server, as you write, will do nothing, because the password is not there at all. It's only in my browser.
And even if the password got somewhere? I have no idea why it should bother me that my wifi password gets somewhere on the internet? In order to be abused, the person in question would have to come near my house. That's pretty unlikely.
And even if someone somehow took the password, somehow found out where I live and arrived here. How specifically could this be abused? The vast majority of the internet today communicates via https, so he wouldn't enjoy it much. So how exactly would he attack me?
You are right, but a lot of people use 1 password in several places, so there is a certain probability that even the password for WIFI will be the same as the password for, for example, a bank...
I doubt many people use the same WIFI password as elsewhere. Especially when they want to go to a website and create a QR code to share this password with their visitors. In that case, they should not show that password to visitors.
I'd like to believe that, but I'm disillusioned with this one :-(
If you are not afraid that your password could be misused, why are you using a password at all?
I see that the gentlemen hack at least the NSA every day, the site generates barcodes completely in client Javascript, so you can easily turn off the Internet or download the application and run it locally so they don't find out. Thanks for the tip for me.
I don't understand the sentence: As we all know, the password is not very good to dictate. If it is a home wifi for visitors, why not just say the password to the visitor? And in other situations I should not share the password at all
No offense to the author, but you must have fallen asleep. This article was presented on a competing website on December 15.12.2017, XNUMX

Foreign websites came to stym even earlier. But even the effort is appreciated...
Jozef: does that mean that if one website wrote it, it must never appear elsewhere? Those are the poor reporters who write about something current. And I believe that people from LsA would not mind publishing here.
how did you find out that this is a competing site? https://textfactory.cz
Should I send info about my network and password to some unknown server to create a QR code? I'd have to be completely stupid...
Nobody wants that from you. Feel free to turn on airplane mode after loading the page, generate a QR code, save it somewhere, close the panel with the page, just to be sure, calmly close the entire browser and only then turn off airplane mode.
The QR code can be easily deciphered
dear,
the paranoids are certainly right, i wouldn't put my wifi password on any server either, but did you read this article properly? The author writes that it is suitable to be added to the menu in a restaurant, for a simple connection to Wi-Fi or for visits to, for example, a company. And perhaps no one would share the connection to the company Wi-Fi, but for the visitor it is faster and more convenient than copying the generated code, with a series of interchangeable characters such as 0 (zero) or O (letter o), 1 (one) or (small letter L). So it's kind of a semi-public network anyway, and it's great for those purposes. Thank you very much!
