WiFi guest network QR code
Print a QR code on a card, a wall sign, or the back of a router. Guests scan, their phone joins the network. No spelling out the password, no typos, no “is it a capital I or a lowercase L”.
The WPA2 string is what your phone reads
A WiFi QR encodes the network name (SSID), the password, and the security type (WPA/WPA2, WEP, or none) into a single string. When you scan, the phone prompts to join. iOS 11+ and Android 10+ both support this natively.
For hidden networks you can also encode the hidden flag, but most home and small-business routers broadcast the SSID. Leave the “hidden” box unchecked unless you specifically need it.
Where to put the QR
On a fridge magnet for Airbnb guests. On the back of a router for a coffee shop. On a laminated card at the reception desk. On a sticker on the inside of a hotel-room door. The QR is the same — the placement changes.
Security note: anyone who scans it gets the password. Treat the printed QR like you’d treat a written password. For a guest-only network with a separate VLAN, this is ideal. For your main network with access to file shares and cameras, use a guest SSID instead.
Make this QR in 30 seconds

- Download the PNG and print it on a card, sign, or fridge magnet
Common questions
Will this work on iPhone and Android?
Yes. iOS 11+ (2017) and Android 10+ (2019) read WiFi QR codes natively with the stock camera app. No app install needed.
Is it safe to print the password in a QR?
Treat the printed QR like a written password. Use a guest SSID with no access to your main network, file shares, or smart-home devices. Rotate the password if you suspect it’s been shared too widely.
