How to create and use your WiFi QR code
Check your router details
Copy the exact network name and choose the matching security type. Use the guest network you intend to share. A network name that looks similar can still refer to a different connection.
Enter the password carefully
Include every capital letter, space and symbol. Use Show password to inspect what you entered. Select the hidden-network option only if the network actually hides its name.
Test joining before displaying
Download the code, disconnect a test phone from WiFi and scan it. Check that the phone joins the intended guest network and can reach the internet, including any separate venue sign-in page.
Use your guest network
A café, accommodation provider or shared workspace should use a separate guest network. Enter the exact network name, including capital letters and spaces. The security setting needs to match your router.
The password is inside the code
Anyone who has the QR image can read the encoded WiFi password. Treat the printed code like sharing the password directly. Keep staff systems and payment devices on a separate network, and update your code when the password changes.
Test from a disconnected phone
Disconnect a test phone from the network, scan the code and check the join prompt. Some devices handle WPA3-only or enterprise networks differently. This generator supports the common WiFi QR format, not enterprise usernames, certificates or captive-portal logins.
Example: a guest card in short-stay accommodation
Put the network name and a “Scan to join guest WiFi” instruction on a card near the welcome guide. Keep a readable password available for guests whose devices do not recognise the code. When you change the router or guest password, replace every copy of the old card, including the image in a digital welcome pack. A QR code makes existing network details easier to share; it does not configure the router.
Illustrative workflow, not a customer case study.Check before you share
- The SSID, security option and password match the router.
- The connection was tested from a device that was not already connected.
- The code is displayed only where you intend to share network access.
