How to Make a QR Code for Your Wi-Fi (So Guests Connect in One Scan)

By Thiago · Updated September 25, 2026 · 2 min read

Spelling out a long Wi-Fi password to every guest, customer or Airbnb visitor gets old fast. A Wi-Fi QR code solves it: people point their phone camera at it, tap once and they are online.

How a Wi-Fi QR code works

The code does not connect to anything by itself and does not go through any server. It simply stores three pieces of text in a standard format that phone cameras understand:

• the network name (SSID),
• the security type (WPA/WPA2/WPA3, the old WEP, or none),
• the password.

Inside the code it looks like WIFI:T:WPA;S:MyHome;P:my-password;;. When a phone reads it, it offers to join that network. Current iPhones and Android phones do this straight from the camera app.

How to create it

1. Open the QR code generator and choose Wi-Fi.
2. Type the network name exactly as it appears on your phone's Wi-Fi list, including capital letters and spaces.
3. Type the password and pick the security type. Almost every modern router uses WPA/WPA2/WPA3. Choose "None" only for an open network.
4. Download it as PNG to share or print at home, or SVG if a print shop will make a sign or sticker.

The code is created in your browser: the network name and password you type are not sent to our server.

Test it before you print

Before printing, scan the code on your screen with two different phones if you can, one iPhone and one Android. If a phone says it cannot join, the usual reasons are:

• a typo in the network name (it is case-sensitive: "MyHome" and "myhome" are different networks),
• the wrong security type,
• a password that was changed on the router after the code was made.

Special characters like ;, : and , in the name or password are fine. The generator escapes them automatically, which is a common reason homemade Wi-Fi codes fail.

Printing tips

• Size: at least 3 cm (about 1.2 in) wide for a table card, bigger for a sign people scan from a distance.
• Contrast: keep the code dark on a light background. Many phones cannot read light codes on dark backgrounds.
• Margin: leave the white border around the code. Scanners need it.
• Add a line of text next to it, such as "Scan to join the Wi-Fi", plus the network name and password in small print for laptops, which usually cannot scan.

Keep your network safe

Anyone who scans the code gets your password, just as if you told them. A few precautions:

• Use a guest network if your router offers one. Guests get internet access without reaching your computers, printers and cameras.
• Do not post a photo of the code online, and do not put it where people outside can scan it through a window.
• Changed the password? Make a new code. The old one stops working, because the password is written inside the code.
