How to Create a QR Code for Your Wi-Fi Password
Let guests join your Wi-Fi with one scan — no typing a long password. Here's how to generate a Wi-Fi QR code for free.
EDTechToolsCenter EditorialReading out a long, mixed-case Wi-Fi password to every guest gets old fast. A Wi-Fi QR code fixes this — a guest scans it with their phone camera and connects automatically, no typing required. It works because the QR code encodes your network name and password directly, in a format phones already understand.
Step-by-step: create a Wi-Fi QR code
- Open the QR Studio and choose the "WiFi" type.
- Enter your network name (SSID) exactly as it appears when you connect manually.
- Enter your Wi-Fi password.
- Select the encryption type — WPA (most home routers) or WEP (older routers); choose "nopass" for an open network.
- Download the QR code as a PNG or SVG, then print it or display it on a screen.

Where this is useful
- A printed card on a cafe or Airbnb table for guest Wi-Fi
- An office reception area, so visitors don't need to ask staff for the password
- A home poster near the router for frequent guests
Is it safe to display?
The QR code contains your actual Wi-Fi password, so anyone who scans it can connect — treat it the same way you'd treat writing the password on a visible sign. For a guest network you don't mind sharing widely, that's fine; for your main home or office network, keep the printed code somewhere only trusted people see it.
Setting up a separate guest network
If you're regularly handing out Wi-Fi access to customers or visitors, most routers support a separate guest network with its own name and password, isolated from your main network and any devices on it. Generate the Wi-Fi QR code for that guest network instead of your primary one — visitors get online without ever having access to your main network's password or the other devices connected to it.
What happens if you change your password
A Wi-Fi QR code isn't linked live to your router — it's a static snapshot of the network name and password at the moment you generated it. If you change your Wi-Fi password later, any printed QR codes from before the change will stop working, so you'll need to generate and reprint a new one to match.
