WiFi Guest Access with a QR Code — Setup for Home, Café or Office
Updated July 20, 2026
Nobody enjoys spelling out a 16-character WiFi password — and guests don't enjoy typing it. A printed QR code lets any phone join your network with one scan. Here's the full setup, from guest network to framed print.
1. Create a guest network first
Almost every router can broadcast a separate guest network — look for “Guest WiFi” in the router settings. Guests get internet access but stay isolated from your own devices, printers and drives. Give it a friendly name and its own password; this is the network your QR code will encode, so your main password never circulates at all.
2. Generate the WiFi QR code
Open the WiFi QR Code tool, enter the guest network's name and password and pick the encryption type (WPA for virtually every modern router). The code encodes the credentials in the standard format Android and iOS understand natively — scanning it connects the phone automatically. The password stays inside the printed code; nothing is sent to any server.
3. Make it look good and print it
For a business, the QR Code with Logo tool puts your logo in the center while keeping the code scannable. Print at least 4×4 cm for table-top scanning; for cafés and waiting rooms, the QR Print Sheet tool fills a page with identical codes to cut out — one for each table.
4. Test before you laminate
Scan the final printed code with both an Android phone and an iPhone from a realistic distance. If a phone struggles, print larger or increase the contrast — dark code on white background works best. Then laminate or frame it: paper codes near coffee machines have short lives.
When you change the password
A static QR code encodes the credentials directly, so a new password means printing a new code. That's a feature, not a bug — the code works forever, needs no service and can't be remotely disabled. Change the guest password occasionally and reprint; your main network stays untouched.
