Spelling out a long WiFi password to guests is often a hassle, especially when it has capital letters, numbers, and symbols. With a WiFi QR Code, guests simply point their phone camera at the QR Code and connect right away.

How a WiFi QR Code works

A WiFi QR Code stores the network name (SSID), security type, and password in a special format that phones recognize, for example WIFI:T:WPA;S:NetworkName;P:Password;;. The built-in camera on iPhones (iOS 11 or later) and most Android phones (Android 10 or later) can read it directly, without any extra app.

Steps to create one

  1. Open the QR Code generator and select the WiFi tab in the Data section.
  2. Type the network name exactly as it appears in the WiFi list, including upper and lower case letters.
  3. Type the password, then choose the security type. Most home and office routers use WPA/WPA2/WPA3.
  4. Check Hidden network if your WiFi name is not shown in the list.
  5. Add a frame with text such as "SCAN WIFI" so guests know what it is for, then download the PNG.

Where to put it up?

  • A small card on café or restaurant tables.
  • The wall of a living room, reception area, or office meeting room.
  • Guesthouse rooms, stuck near the door or the TV.
  • The underside of the router at home, so family members can easily connect new devices.

Security tips

  • Use a guest network if your router supports it, so guests do not join the same network as the office computers.
  • If the WiFi password is changed, create and reprint the QR Code, because the old QR Code will contain the old password.
  • Do not put up a WiFi QR Code for a private network in a public place where anyone can take a photo of it.

If the QR Code does not connect

Double-check the spelling of the network name and password, because a single wrong letter will make the phone fail to connect. Also make sure the selected security type matches the router settings. For other scanning problems, read reasons a barcode won't scan.

Frequently Asked Questions

Can every phone scan a WiFi QR Code?

The built-in camera on iPhones with iOS 11 or later and most phones with Android 10 or later can read it directly. Older phones may need a QR scanner app.

Is a WiFi QR Code secure?

Anyone who scans the QR Code can connect to your WiFi. For that reason, use a guest network and do not put up a QR Code for a private network in a public place.

What should I do if the WiFi password is changed?

Create and reprint the WiFi QR Code, because the old QR Code still contains the old password.
