Written as T:WPA, the value the WPA3 specification gives WPA2 and WPA3 alike, which iPhones and Android's Wi-Fi settings read.

How do I make a QR code for my WiFi?

Type the network name (SSID) and password exactly as your router's admin page shows them, upper and lower case included, and pick the security; the QR code for your WiFi appears as you type. Download it as SVG, PNG or PDF, or print it as a Wi-Fi card with the network and password written out for anyone whose phone can't scan.

The code is made in your browser: the password isn't uploaded, isn't written into the page's address and is gone when you close the tab. This page is our QR Code Generator opened on Wi-Fi, so the same tool also makes link, contact and payment codes.

How does a WiFi QR code work?

A WiFi QR code holds one short line of text, WIFI:T:WPA;S:<network name>;P:<password>;;: the security type, the network name and the password. The phone's camera reads it and offers to join the network, so nobody types the password (ZXing's format).

The Wi-Fi Alliance made the same format a standard in its WPA3 specification, with R:1 for WPA3-only networks. The code connects nothing by itself: the phone does, once you tap Join.

A WPA3-only network gets R:1, so WPA3 devices never fall back to WPA2.

Does a WiFi QR code work on iPhone and Android?

Yes. The iPhone Camera has offered to join networks from QR codes since iOS 11 (Apple). On Android, Settings has scanned and shared Wi-Fi codes since Android 10, in the Wi-Fi list: Network & internet › Internet on Android 12 and later, Network & internet › Wi-Fi on Android 10 and 11, and wherever the phone maker puts it (Samsung: Connections › Wi-Fi). Whether the camera app joins too depends on the phone maker, though Google's Pixel Camera does (Android Help).

Hidden networks are the exception: Apple said the iPhone camera doesn't support them, and no later statement says otherwise, so test a hidden network's code on a guest's iPhone before you print it.

How do I make a WiFi QR code for WPA3 or a hidden network?

Pick the security your router shows. WPA2, WPA3 and mixed WPA2/WPA3 networks are all written T:WPA, the value the WPA3 specification gives every password network, and a WPA3-only network also gets R:1, so WPA3 devices never fall back to WPA2. We never write T:WPA3: an iPhone tested in 2021 didn't recognise it (Apple Developer Forums).

For a hidden network, tick Hidden network and the code adds H:true. A ; , : \ or " in the name or password gets a backslash in front, the way Android and ZXing read it; the WPA3 specification writes a semicolon as %3B instead, so if yours has one, test the printed code on a phone.

How do I print a WiFi card for guests?

Choose Wi-Fi card above the code and download the PDF: it prints the code with the network name and password written out, for guests whose phones can't scan. The card is business-card size, for a counter, a desk or a fridge door, and the PDF can also put ten of them on one A4 sheet to cut out.

Print on matt paper, keep the white margin round the code, and make a new card whenever you change the password: the old code keeps the old one. The reach below is the tool's own estimate (a module at least 1/250 of the scanning distance, worked out from QR vendors' 10:1 rule of thumb).

WiFi QR code FAQ

Is it safe to share WiFi with a QR code?

It's as safe as writing the password on a card: anyone who scans the code can read the password in plain text. So print it for a guest network rather than the one your own computers use, keep it inside your premises, and make a new code whenever you change the password. The code itself is made in your browser and never uploaded.

Does a WiFi QR code work on iPhone?

Yes, since iOS 11: open the Camera, point it at the code and tap the banner to join. The iPhone reads T:WPA, which we write for WPA2 and WPA3 networks alike. Two cautions: Apple said hidden networks aren't supported from a code, and a network without a security type in its code may fail, which is why we always write one.

How do I scan a WiFi QR code on Android?

Open the Wi-Fi list in Settings and tap the QR icon beside Add network, there since Android 10. The list is under Network & internet › Internet on Android 12 and later, Network & internet › Wi-Fi on Android 10 and 11, and Connections › Wi-Fi on a Samsung; other makers move it. Many camera apps also offer to join, Google's Pixel Camera among them, but that depends on the phone maker.

Can I make a QR code for a hidden network?

Yes: tick Hidden network and the code adds H:true, which Android reads. iPhones are the catch, as Apple said its camera doesn't support hidden networks from a code. Test the printed code on an iPhone before you rely on it, or make the guest network visible and keep the hidden one for your own devices.

Does a WiFi QR code work with WPA3?

Yes. WPA3 and mixed WPA2/WPA3 networks are written T:WPA, the value the Wi-Fi Alliance's WPA3 specification uses for every password network, and phones then connect with WPA3 where both sides support it. For a WPA3-only network we add R:1, so WPA3 devices never fall back to WPA2. We never write T:WPA3, which an iPhone didn't recognise.

What if my WiFi password has a ; or a comma?

Type it as it is: we put a backslash before ; , : \ and " in the name and password, the escaping Android and ZXing-based readers expect, so phones read it exactly. The WPA3 specification writes a semicolon as %3B instead, so if your password or network name has one, test the printed code on an iPhone and an Android phone.

Does a WiFi QR code expire?

No, the code itself never expires: it's static, with the network and password in its squares, and no server is involved. It stops working when the network changes: a new password, a new network name or a new security type. Then make a new code and replace the old prints, because they still carry the old password.

How do I share WiFi from my own phone as a QR code?

On an iPhone, the Passwords app shows Show Network QR Code for a saved network. On Android 10 and later, open the Wi-Fi list in Settings (Network & internet › Internet from Android 12, Connections › Wi-Fi on a Samsung), tap the network you're on (on a Samsung, the gear beside it) and choose Share or QR code. Both show a code on screen; this generator makes one you can style, print and leave on a table.

What does WIFI:T:WPA;S:;P:;; mean?

It's the text inside a WiFi QR code. T is the security (WPA, WEP or nopass), S the network name, P the password, and H:true marks a hidden network; each part ends with a semicolon and the whole record with two. In WIFI:T:WPA;S:;P:;; the name and password are empty, so a phone has nothing to join.

Can I add a logo to a WiFi QR code?

Yes. Open the Logo tab and pick the Wi-Fi mark or your own logo, such as your café's. The generator switches error correction to level H, keeps the logo near 10 % of the code's area and reads the code back before you download it. Keep the network name and password printed beside the code for phones that can't scan.
