A WiFi QR code encodes your network credentials using a standardized text format that both iOS and Android understand natively. The format is: WIFI:T:WPA;S:MyNetwork;P:MyPassword123;;. When a phone scans this QR code, the operating system parses the string, extracts the network name (SSID), password, and encryption type, and prompts the user to join the network — all without typing a single character. The standard was developed by the WiFi Alliance and is supported on iOS 11 and later, Android 10 and later, and most modern versions of both platforms.
The beauty of WiFi QR codes is that they transform a typically painful interaction — "what's your WiFi password? Is it uppercase or lowercase? Is that a zero or the letter O?" — into an instant, one-tap connection. For homes, it eliminates the conversation entirely. For businesses, it removes a recurring source of friction for every new customer who walks through the door.
Creating a WiFi QR code takes under a minute. Open our free QR code generator, select the WiFi content type from the dropdown, and fill in three fields:
Network Name (SSID): The exact name of your WiFi network as it appears in the list of available networks. This is case-sensitive — "MyHome" is different from "myhome." Double-check the spelling and capitalization before generating.
Password: Your WiFi password. If your current password is something like "password123" or your router's default, now is a good time to replace it with a stronger one. Use our password generator to create a long, random password that is resistant to guessing. Since your guests will scan a QR code rather than type the password manually, you can use a maximally strong 20-character random string without any usability penalty — the phone handles the typing for them.
Encryption Type: Select WPA/WPA2 for the vast majority of modern routers. WEP should only be selected if your router is extremely old (pre-2004) and still uses that protocol — but honestly, if your router uses WEP, replace the router. Select "None" only for open, unsecured networks, which are not recommended except for short-term event networks in controlled environments.
Click Generate, and your WiFi QR code is ready. Test it immediately by scanning it with your own phone to confirm it connects correctly. There is nothing worse than printing 50 cards only to discover the password had a typo.
The scanning experience differs slightly between platforms, but both handle WiFi QR codes natively — no third-party app required.
On iPhone (iOS 11+): Open the Camera app, point it at the QR code. A yellow notification banner appears at the top of the screen reading "Join [Network Name] Network?" — tap it. Alternatively, open the built-in Code Scanner from Control Center (add it via Settings → Control Center if it is not already there). The phone connects instantly using the stored credentials.
On Android (Android 10+): Most Android phones can scan QR codes directly from the Camera app — point and tap the notification. On Samsung devices, open the Camera app and make sure QR code scanning is enabled in Camera Settings. On Pixel and stock Android devices, the Google Lens integration in the camera handles it automatically. If the camera does not work, Google Lens (pre-installed on most Android phones) or any QR scanner app will also process WiFi codes correctly.
A note on older devices: Phones running iOS 10 or earlier, or Android 9 or earlier, may not support WiFi QR code scanning natively. For these rare cases, the QR code can still display the password in plain text when scanned with a generic QR reader — the user will need to type it manually. The vast majority of active phones today support native WiFi QR code flow.
At Home: The classic use case. Print a small card or sticky label with your WiFi QR code and place it on the fridge, inside a drawer, or framed on the living room shelf. Houseguests scan and connect without asking. If you host Airbnb or short-term rentals, a WiFi QR code in the welcome guide eliminates the number one guest question. For extra security, consider setting up a guest network through your router's admin panel and generating the QR code for that network, keeping your personal devices and file shares on a separate, unshared SSID.
At the Office: Print a large, laminated WiFi QR code for the conference room, reception area, or break room. Employees and visitors connect instantly. Rotate the password periodically (monthly or quarterly) and reprint the QR code — since QR codes are static, the printed code must be updated when the password changes. For offices that use enterprise authentication (802.1X), WiFi QR codes do not apply; the standard only covers personal WPA/WPA2 networks.
At a Cafe or Restaurant: A WiFi QR code on each table — either as its own small card or integrated into the same sign as the menu QR code — lets customers get online without asking staff. Combined with a captive portal that requires email signup (configured through your router's guest network settings), it also becomes a lightweight marketing tool. The QR code should be printed at minimum 2.5 cm across at error correction level M or Q to survive the moisture, heat, and cleaning chemicals common in food service environments.
A WiFi QR code contains your network password in plain text. Anyone who can see the printed code can extract the password — either by scanning it and inspecting the notification, or by using a generic QR scanner app that displays the raw decoded text. This is not a flaw; it is how the standard works. The WiFi Alliance designed the format for convenience, not secrecy.
This has practical implications. Do not use a WiFi QR code for your primary network if that network provides access to sensitive file servers, security cameras, or personal computers with open shares. Instead, configure your router to create a separate guest network — most modern routers support this with a few clicks in the admin panel. The guest network should have internet access only, isolated from your main LAN. Generate the QR code for the guest network credentials. This way, even if a QR code walks out the door with a former employee or a cafe customer, they cannot reach anything sensitive.
For cafes and public spaces, additional layers include enabling client isolation on the guest network (prevents guests from seeing each other's devices), setting bandwidth limits to prevent one user from saturating the connection, and — if you want to get sophisticated — using a router that supports dynamic QR codes via a captive portal, where the password changes daily and the portal displays a fresh QR code on a screen behind the counter.
For maximum WiFi security, pair a strong password with WPA3 encryption (available on routers manufactured after 2018). WPA3 eliminates the offline dictionary attack vulnerability that WPA2 has, meaning even if someone captures the handshake and extracts the QR code password, they cannot brute-force additional credentials. The QR code format works identically with WPA3 networks — just select WPA in the encryption dropdown.
Enter your network name and password, generate a QR code, and never spell out your WiFi password again. Free, instant, no account required.
