Wi-Fi QR Code
A code a guest scans to join, so the password is never read aloud.
Reading a long Wi-Fi password down the table, or typing it into a guest's phone, is the slow part of having people over. A Wi-Fi QR code fixes that. A guest points a camera at it and joins. This tool builds the code entirely in your browser from the network name and password, so nothing you type is stored or sent anywhere. It is as useful in a guest house, an Airbnb or a holiday let, where a small printed code by the door lets each visitor get online themselves without a message or a knock. The code itself holds the password, so a printed code is the password, and you put it where only people you trust can see it.
Enter a network name to make a code.
The code holds the password in plain form, so anyone who scans it joins the network. Treat a printed code like the password itself. Made in your browser; nothing is stored or sent.
Turn on JavaScript to make a Wi-Fi code. Nothing is sent anywhere; the code is made on your device, never stored.
How to use it
Type the network name and password, pick the security type, and the code appears. Download it to print or share.
Name it exactly
Type the network name as it appears on your devices, capital letters and all, since a code with the wrong name will not connect. Then type the password into the password field. Use the show button to check it reads correctly before you trust the code.
WPA for almost everything
Leave the security on WPA, which covers WPA2 and WPA3 as well, unless you know your network uses old WEP or has no password at all. Tick hidden network only if yours does not show up in the list of nearby networks.
Print it where guests sit
Press Download to save the code as an image, then print it and put it where guests can reach it, like by the kettle or on the fridge. Treat that paper like the password, because anyone who can see it can join.
Why this is safe
A tool that takes your Wi-Fi password has to earn trust by doing as little as possible with it. This one does nothing beyond drawing the code.
The code is built on your device as you type, using a QR encoder bundled with the page. The network name and password live only in the fields and the code on screen. There is no server in the loop, no account, no logging, and nothing written to storage. Close the tab and the fields are empty again.
The strongest proof is simple: turn off your connection and the tool still works, because there was never anything to send.
A Wi-Fi code is convenient because it carries the password, which is also the one thing to keep in mind. A photograph of the code is enough to join your network. Put a printed code where only people you would give the password to can see it, and take it down if you would not hand them the password directly.
For guest houses and short stays
If you host, the code answers the most common guest question before it is asked: what is the Wi-Fi password.
A guest house, an Airbnb, a B&B or a holiday let runs more smoothly when a visitor can get online the moment they arrive. Print the code and put it where they will look, in the welcome pack, on the fridge, beside the television or framed by the door. A guest scans it and joins, with no message to you and no password read down the phone. For an unattended or self check-in let, that is one less thing to support at the moment a guest is settling in.
Keep the code on a network set aside for guests, so a visitor’s device never reaches the equipment you run the place on. When you change the password between stays, make a fresh code and swap the printed copies.
Download the code and drop it into your house manual or welcome sheet, then print it at the size that suits the spot. A laminated copy by the door survives a season of guests, and a fresh one takes a minute to make when the password changes.
Best on a guest network
At home or in a rental, the code belongs on a network you are happy for visitors to use, kept apart from the devices that matter.
A guest network is a separate lane on the same router, so a visitor’s phone, or a borrowed laptop, never reaches the computers you bank and work on. Put the code on the guest network and people can join in a second without you reading out a password or touching their phone. If a guest’s device is later found to be compromised, it was never near your real devices to begin with.
Most routers can run a guest network alongside the main one, often with a tick box and a name of its own. The Front Door guide walks through turning one on and splitting your home, or your let, into separate lanes, which is the setup this code is made for.
Common questions
The questions people ask before they print their Wi-Fi password as a code.
Is the password saved or sent anywhere?
No. The code is built in your browser from what you type, shown only on screen, and never sent to any server or written to storage. Reload the page and the fields are empty again. The download button saves the image to your device, and nothing more. You can turn off your connection first and it still works, which is a good test of any tool that claims to keep nothing.
Does the QR code hide my password?
No, and it is honest to say so. The code holds the network name and password in plain form, the same way a printed label would. Anyone who scans or photographs the code can read the password and join the network. The code saves typing, not secrecy, so put a printed one where only people you would give the password to can reach it.
Which security type should I choose?
WPA covers WPA2 and WPA3 as well, so it is the right choice for almost every home network today. Pick WEP only for old equipment that still uses it, which is rare and worth replacing. Pick None for an open network with no password, where the code carries only the name.
What is a hidden network?
A hidden network is one that does not broadcast its name, so it does not appear in the list of nearby networks until you type the name in. If yours is set up that way, tick hidden network so a scanning phone knows to look for it. If you are not sure, leave it unticked, since most home networks are not hidden.
Will it work on an iPhone and an Android phone?
Yes. The camera app on a current iPhone and on most Android phones reads a Wi-Fi code and offers to join when you point it at the code. On older phones a free QR scanner app does the same. Nothing needs installing on your side to make the code.
Is this good for an Airbnb or guest house?
Yes, that is one of its best uses. A printed code in the welcome pack or by the door lets each guest join the moment they arrive, with no message to you and no password read out. It suits self check-in and unattended stays, where there is nobody on hand to help. Keep it on a guest network so visitors stay off the equipment you run the place on, and make a fresh code whenever you change the password.
Should I use this for my main network?
It works for any network, but a guest network is the better fit. A guest network keeps visitors off the devices you bank and work on, and a code by the kettle lets them join without you handing over the main password. The Front Door guide sets up a guest network on most routers.
What happens if I change the password?
The old code stops working, because it carries the old password. Make a fresh code with the new password and replace any printed copies. This is a good reason to keep the printed code somewhere you can find and swap it.
