A WiFi QR code turns a password nobody wants to type into one camera scan.

What a WiFi QR code does
A WiFi QR code stores the network name, security type, and password in a format phones can recognize. When a guest scans it, the phone can offer to join the network without making them type a long password.
This is useful anywhere people ask for the same network details again and again: cafes, salons, short-term rentals, clinics, coworking rooms, offices, and family homes.
Use the exact network name
Network names are case-sensitive. If the router says `CafeGuest_5G`, do not type `cafeguest_5g`. A tiny typo can make the QR look valid while still failing to connect.
If the network is hidden, test the code more carefully. Hidden networks can behave differently across phones, and guests may need extra instructions.
- Copy the SSID from router settings when possible.
- Choose the correct security type, usually WPA or WPA2/WPA3.
- Regenerate the QR when the password changes.
Keep guest networks separate
A WiFi QR code makes access easier, so use it with the network you actually want to share. For businesses and rentals, that usually means a guest network, not the private router network used for admin devices, printers, registers, or cameras.
Print the QR where guests need it, but do not put it in public photos if the password should stay limited to people on-site.
Where to place the code
Put the QR code near the moment of need: reception desks, table tents, room welcome cards, checkout counters, meeting rooms, or rental house guides. Include the network name in text beside it so guests can confirm they joined the right network.
If you print it small, keep the design simple. WiFi QR codes can become dense when the network name and password are long.
Quick workflow
Steps to follow
Choose WiFi in the app
Select the WiFi QR type instead of using a plain text QR.
Enter the exact SSID
Type the network name exactly as it appears in router or device settings.
Pick the security type
Use the security option that matches your router, most commonly WPA.
Test before printing
Scan with another phone and confirm it joins the expected guest network.
Common questions
Before you print or share
Can iPhone and Android scan the same WiFi QR code?
In most normal WPA network cases, yes. Still test before printing because router settings and hidden networks can vary.
Should I use a guest network?
Yes for businesses, offices, rentals, and events. A guest network limits what visitors can access after they connect.
Do I need to update the QR if the password changes?
Yes. Static WiFi QR codes store the password itself, so a password change means generating a new QR code.
