How to Share WiFi with a QR Code
Typing WiFi passwords is slow and error-prone. A WiFi QR code lets guests connect by scanning with their phone camera. This guide shows a simple, safe setup that works in cafes, homes, offices, and events.
Step-by-step instructions
- Open the WiFi QR Generator.
- Enter your WiFi name (SSID) exactly as it appears.
- Choose the correct security type and add the password.
- Generate the QR code and test with two devices.
- Download the QR code as PNG or SVG for sharing or printing.
- Place the QR code where guests can see it easily.
Start with a guest network
The safest way to share WiFi is to use a guest network. Guest networks keep visitors separate from your personal devices, which is important in homes and businesses. If your router supports it, create a separate SSID for guests and set a password that you can change occasionally.
If you cannot create a guest network, keep your WiFi QR code in a location where only your audience can access it. For example, place it behind a counter or inside a private office rather than on the front door.
Use the exact WiFi name and security
The WiFi QR code must match your network details exactly. Copy the SSID (network name) from your router settings or phone and paste it to avoid mistakes. Then select the correct security type. Most networks use WPA or WPA2. If you choose the wrong security type, scanning will fail even if the password is correct.
If your network is hidden, make sure to toggle the hidden option when generating the QR code. This helps scanners connect to networks that do not broadcast their name.
Test before you share
Always test the QR code. Scan with your phone camera and a second device if possible. Confirm the network name is correct and the phone joins without errors. If it fails, check for typos and make sure the security type is correct. Regenerate the QR code after any password change.
A quick test saves you from printing the wrong code or confusing guests during a busy time.
Place the QR where it is easy to scan
The best placements are eye-level and easy to reach: front desks, counters, table tents, or welcome booklets. Avoid shiny surfaces that reflect light, and make sure there is enough space around the QR code so phone cameras can focus.
For busy locations like cafes, print multiple codes in different places so guests do not crowd one spot.

Share digitally or print
PNG works well for social posts, emails, or digital menus. SVG is best for printing because it stays sharp at any size. If you are printing more than one WiFi QR, use the print sheet to place multiple codes on one A4 page.
Make the sign clear and friendly
People scan faster when they know what will happen. Add a short label such as "Scan to join WiFi" and show the network name so guests can confirm they are connecting to the right place. If you run a business, add a tiny note like "Ask staff if you need help" so people feel supported.
- Use large, simple text that is easy to read.
- Show the network name near the QR code.
- Keep the password private if the sign is public.
- Update the print if you change the password.
For homes, place the QR near the entry or on the fridge. For businesses, a small stand or frame keeps the paper clean and avoids curled edges that can block part of the code.
A clear label reduces questions and improves trust, especially for first-time visitors.
Common mistakes and quick fixes
- QR does not scan: increase size or shorten the distance to the code.
- Wrong network: double-check the SSID and hidden network toggle.
- Wrong password: update the QR code after changing WiFi settings.
- Guests ask what to do: add a short label like "Scan to join WiFi".
Keep the QR code updated and placed where it is visible. That small effort reduces friction and improves the guest experience.
