Settings guide
Encryption type:
| Option | When to use |
|---|---|
| WPA/WPA2/WPA3 | Most home and business routers — select this |
| WEP | Very old routers only — WEP is insecure, consider upgrading |
| None | Open networks with no password |
SSID (network name): Enter exactly as it appears in your router settings. Capitalization and spaces matter.
Hidden network: If your SSID is hidden (not broadcast), enable the "Hidden network" option. This tells the phone to join without first searching for the broadcast SSID.
Password special characters: Passwords containing commas, semicolons, backslashes, or double quotes may require escaping in the QR string. This generator handles escaping automatically — just paste your password as-is.
Test before printing: Temporarily disconnect your phone from the WiFi, then scan the code to verify it connects correctly. Test on both iOS and Android if both are in your environment.
Format comparison
vs sharing verbally or on a sign with text: A printed WiFi password sign has readability issues (Is that a zero or the letter O? Capital I or lowercase l?), requires typing, and is trivially photographed by anyone. A QR code is faster for legitimate users and provides no advantage to people trying to screenshot the password — they can just scan the QR themselves.
vs a guest network with a simple password: Using both is ideal. Set up a separate guest network with a simple, rotating password. Generate a QR code for it. The QR removes typing friction. The guest network isolates visitors from your primary network. Rotate the password weekly or monthly and regenerate the QR.
vs NFC tags: NFC tags (writable chips in stickers or cards) can also store WiFi credentials and connect on tap without a camera. NFC requires purchasing and writing physical tags; QR codes require only a printer. NFC works without visual alignment; QR requires pointing the camera. Both work on modern phones.
How it works
Enter network details
Type your WiFi network name (SSID), password, and select the security type (WPA2 for most modern routers).

About this format
A WiFi QR code lets anyone connect to your network by pointing their phone at a printed or displayed code — no typing the password, no reading it over the shoulder, no repeating it three times. The guest's phone scans the code, confirms the connection, and joins the network in under two seconds.
The use cases are everywhere: a coffee shop prints it on a table tent, a hotel puts it on the room key card, an office reception desk has it on a framed card, a coworking space puts it on the wall, a short-term rental host sticks it to the fridge. It solves the "what's the WiFi password?" friction permanently.
This generator creates the QR code entirely in your browser. Your WiFi password is processed locally in JavaScript and never transmitted to any server. The QR code is rendered on your device and downloaded directly. No account, no logs, no server.
The QR code encodes a standard WiFi connection string: `WIFI:T:WPA;S:NetworkName;P:Password;;`. Any modern smartphone (iOS 11+, Android 10+) reads this format natively using the built-in camera — no QR scanner app required.
