WiFi QR Code Generator
A WiFi QR code stores your network name, security type, and password so a phone joins the network by scanning instead of typing the password.
Fill in: Network name (SSID)
A WiFi QR code is a plain-text instruction to a phone’s WiFi settings. It carries the network name, the security type, and the password, formatted so the camera app can join the network without anyone typing anything.
How to make a WiFi QR Code
- Type your network name exactly as it appears in phone WiFi settings, including capitals.
- Choose the security type. Almost every modern router uses WPA.
- Enter the password. Leave it blank only if the network is genuinely open.
- Download the PNG for screens or the SVG for printing, then print it at 4 cm or larger.
- Test it with two phones — one Android, one iPhone — before putting it on the wall.
WiFi security types and QR support
| Security | Payload value | Scans on modern phones | Notes |
|---|---|---|---|
| WPA / WPA2 / WPA3 | WPA | Yes | Use this unless your router is very old. |
| WEP | WEP | Mostly | Deprecated and insecure; replace the router. |
| Open network | nopass | Yes | No password field is written into the code. |
Frequently asked questions
Does a WiFi QR code expose my password?
Yes. The password is stored in plain text inside the code, so anyone who scans it can read it. Use a guest network for a code you put on a wall.
Do iPhones and Android phones both support WiFi QR codes?
Yes. iOS 11 and later joins from the camera app; Android 10 and later joins from the WiFi settings screen or a camera app that supports it. Older Android phones may need a separate QR scanner app.
How big should I print a WiFi QR code?
At least 4 cm across for a table tent read at arm's length. The rule of thumb is one tenth of the scan distance.
Can I change the network later without reprinting?
No. The password is baked into the code, so changing the network means printing a new one.
