How to create a Wi-Fi QR code
A Wi-Fi QR code joins a phone to the network in one scan: no reading out a long password, no typos. Current iPhones and Android phones read it straight from the camera.
Steps
- Enter the network name exactly as it appears, capitals included.
- Choose the security type: WPA for almost every modern router.
- Enter the password.
- Scan the code with a phone that is not connected yet to test it.
What the code holds
The code stores the network name, the security type and the password in a standard format that phone cameras recognise. There is no link and no server in between: the phone reads the details and connects.
Pick WPA for WPA, WPA2 and WPA3 networks — that covers practically every router sold in recent years. WEP is obsolete and insecure, and "none" is only for open networks. If the network is hidden, tick that option, or phones will not find it.
Share a guest network, not your main one
Anyone who scans the code gets the password, and can read it back from the code. In a shop, office or rental, create a guest network on the router and print the code for that one, keeping your computers and cameras on a separate network.
When the password changes
The password is inside the code, so changing it on the router makes every printed code stop working. Generate a new code and replace the printed ones the same day.
Frequently asked questions
Can a Wi-Fi QR code contain the password?
Yes, that is what makes it work: the phone reads the name, the security type and the password, and connects.
Does it work on any phone?
Current iPhones and Android phones read Wi-Fi codes from the camera. Older models may need a QR reader app.
Is it safe to put a Wi-Fi QR code on the wall?
Only for a network meant for guests. Treat the code like the password itself.
Is my password sent anywhere?
No. The code is generated in your browser; the password never leaves your device.
