WiFi QR codes: set one up for your space
Let guests join your WiFi by scanning a code instead of typing a password — how it works, how to make one, where to put it, and how to keep your network safe.
In short
A WiFi QR code encodes your network name, security type and password so guests join by scanning instead of typing. Make it dynamic so a password change is a quick edit rather than a reprint, label it clearly, and put guests on a separate network to keep your main devices safe.
Reading a password off a wall and typing it without a typo is a tiny, daily annoyance for everyone who visits your space. A WiFi QR code removes it: guests scan, tap "Join", and they are online. This guide explains how it works and how to roll one out without compromising your network.
How a WiFi QR code works
The code encodes your network name (SSID), the security type, and the password in a format phones understand. When someone scans it, their phone offers to join that exact network — no typing, no spelling out "zero or letter O".
Create one in CoreQR
Choose the WiFi code type, enter your network details, and style it to match your space. A dynamic code is worth it here: if you rotate the password, you update the code once instead of reprinting every sign.
- Enter the exact network name and password
- Pick the right security type (usually WPA/WPA2)
- Add your logo and a short "Scan to join WiFi" label
- Export as SVG for crisp printing at any size
Where to put it
Place it where people naturally wait or sit, at a height that is easy to scan from a phone. A small "Scan to join WiFi" caption tells people what it does — never assume the code explains itself.
- On the table or menu in a cafe or restaurant
- At reception, in waiting rooms and meeting rooms
- In rental properties, hotel rooms and Airbnbs
Keep your network safe
Sharing WiFi by QR code is convenient, but treat your guest password like a public one. The safest setup separates guests from the rest of your network entirely.
- Use a dedicated guest network, not your main one
- Pick a strong guest password and rotate it periodically
- With a dynamic code, a password change means one quick edit
FAQ
Is a WiFi QR code safe?+
It is as safe as the password it shares. Put guests on a separate guest network so a shared code never exposes your main devices, and rotate the password from time to time.
What happens if I change the WiFi password?+
A static WiFi code would need reprinting. A dynamic CoreQR code can be edited in seconds, so every printed sign keeps working after a password change.
Do guests need an app to scan it?+
No. Modern iPhone and Android cameras read WiFi QR codes natively and prompt to join the network.
