How to make a Wi-Fi QR code guests can scan to connect

What a Wi-Fi QR code does

A Wi-Fi QR code stores your network name, password and security type. When someone scans it with the camera app on a modern iPhone or Android phone, the phone offers to join the network directly — no reading a password off a sticker and mistyping it. It is ideal for homes, cafés, offices, rental properties and events.

Step by step

Open the QRinst generator and choose the Wi-Fi type.
Enter the network name (SSID) exactly as it appears, including capital letters and spaces.
Enter the password and pick the security type — WPA/WPA2/WPA3 for almost every modern router.
Tick "hidden network" only if your router does not broadcast its name.
Download the code and test it on a phone that isn't already connected.

Which security type should I choose?

Check your router's settings page if you're unsure. WPA2 and WPA3 networks both use the WPA option. Choose "None" only for an open network with no password. WEP is obsolete and insecure; if your router still uses it, upgrading its security setting is worth doing before sharing access more widely.

Your password stays private

A Wi-Fi code is a static QR code, and QRinst generates static codes entirely in your browser — the password is never sent to or stored on our servers. Keep in mind the password is readable by anyone who scans the printed code, so treat the printout like the password itself.

Good practice for businesses

Share a separate guest network, not the one your tills, cameras or staff computers use.
If you change the password, the old code stops working — print a new one.
Add a short label such as "Scan to join Wi-Fi" so people know what the code is for.
Place it where people wait: tables, reception desks, room information cards.

If it doesn't connect

Most failures come from a typo in the network name or password, or the wrong security type. Double-check each field. Very old phones may need a separate QR scanner app, and some corporate (WPA-Enterprise) networks that require a username cannot be joined with a standard Wi-Fi QR code.
