How It Works
Enter Your Network Details
Type your WiFi network name (SSID) and password into the form above. Select the security type your router uses — most home and business networks use WPA/WPA2. If your router supports the newer WPA3 standard, select that instead. For networks without a password, choose "None (Open)."
Generate and Customize
Your QR code generates instantly as you type. The code uses the standard WIFI: protocol format that smartphones recognize natively. Customize the design with your brand colors, add a logo, or wrap it in a frame with a call-to-action like "Scan to Connect" to make it inviting.
Print and Display
Download the QR code as a high-resolution PNG for screens or SVG/PDF for print. Place it on a table tent, mount it near the entrance, include it in your welcome packet, or frame it on the wall. Guests simply open their phone camera and scan — no app required.
Understanding WiFi Security Types
WPA / WPA2
The most widely used security standard. WPA2 has been the default on routers since 2006 and is supported by virtually every device. If you are unsure which encryption your network uses, WPA/WPA2 is almost certainly the right choice.
WPA3 (SAE)
The latest security protocol, offering stronger encryption and protection against brute-force attacks. Newer routers (2020 and later) may support WPA3. Check your router settings to confirm. Older devices may not connect using WPA3.
WEP (Legacy)
An outdated encryption standard with known vulnerabilities. WEP is only included for backward compatibility with very old hardware. If your network still uses WEP, consider upgrading your router to one that supports WPA2 or WPA3.
None (Open)
For networks with no password. Common in public spaces, guest hotspots, or captive portal setups. Open networks do not encrypt traffic, so they should be used alongside a captive portal or VPN for any sensitive use.
Popular Use Cases
Restaurants and Cafes
Print a WiFi QR code on table tents, menus, or receipts. Customers connect without bothering the staff, and you avoid repeating the password dozens of times a day. Pair it with a "Scan for Free WiFi" call-to-action.
Hotels and Airbnb
Include the QR code in your welcome packet, on the nightstand card, or framed in the room. Guests appreciate not having to type a long, complex password on arrival. Update the code whenever you change the password between stays.
Offices and Co-Working Spaces
Display the guest WiFi QR code in the lobby, meeting rooms, and reception area. It streamlines onboarding for visitors, contractors, and new hires. Use a dedicated guest network to keep your corporate network secure.
Events and Conferences
Add WiFi QR codes to event badges, signage, or projection screens. Hundreds of attendees can connect quickly without a single support ticket. Large events benefit from placing QR codes at multiple access points throughout the venue.
Hospitals and Clinics
Offer patients and visitors easy WiFi access in waiting rooms. A printed QR code on the wall reduces front-desk inquiries and keeps staff focused on care. Make sure the guest network is isolated from medical systems.
Retail Stores
Encourage customers to connect while they browse. In-store WiFi enables your app, loyalty programs, and digital catalogs. Place QR codes near the entrance and at checkout for maximum visibility.
How to Find Your SSID and Password
Check the Router Label
Most routers have a sticker on the bottom or back that shows the default SSID (network name) and password. If you have not changed these, the label values will work. The SSID is case-sensitive, so type it exactly as shown.
Log In to Your Router Admin Panel
Open a browser and go to your router's IP address (commonly 192.168.0.1 or 192.168.1.1). Sign in with the admin credentials — often printed on the same label. Navigate to the Wireless or WiFi settings page to see or change your SSID and password.
Check Your Device Settings
On Windows, open Network & Internet settings and click "Show" next to your saved WiFi password. On macOS, open Keychain Access and search for your network name. On a phone, you can often share the WiFi password from Settings if you are already connected.
Guest Network Best Practices
- Always use a separate guest network instead of sharing your main network password. This isolates guest devices from your computers, printers, and smart home devices.
- Set a strong password for the guest network, even if it is a temporary one. The QR code makes it painless for guests to enter a complex password.
- Enable client isolation on your guest network so that connected devices cannot see or communicate with each other.
- Set bandwidth limits on the guest network to prevent one user from consuming all your bandwidth.
- Rotate the guest password periodically — monthly for offices, between each guest for short-term rentals. Print a new QR code each time you change it.
Tips for Best Results
- Update your QR code whenever you change the WiFi password. An outdated code will frustrate anyone who scans it. Keep a bookmark to this page so you can regenerate a new code in seconds.
- Use a guest network for shared QR codes. Never share the password to the network where your personal devices and sensitive data live.
- Print the QR code at a size of at least 2 cm (about 0.8 inches) for reliable scanning. Larger is better, especially for wall-mounted signs that people scan from a distance.
- Laminate printed QR codes to protect them from wear, moisture, and fading. A laminated card lasts months without degradation.
- Test the QR code on at least two different phones before distributing it. Scan with both an iPhone and an Android device to confirm the connection works.
- Add a frame with a call-to-action like "Scan for WiFi" or "Connect to Free WiFi" so people understand what the QR code does at a glance.
- If your network name contains special characters like semicolons, commas, or backslashes, the generator handles escaping automatically. Just type the name as-is.
- For hidden networks, check the "Hidden network" option. This tells the scanning device that the SSID is not broadcast and needs to be connected manually if QR auto-connect is not supported.
Frequently Asked Questions
Which phones and devices can scan WiFi QR codes?
WiFi QR codes are natively supported on iPhones running iOS 11 or later (2017+) and Android devices running Android 10 or later (2019+). Simply open the built-in camera app, point it at the QR code, and tap the notification to connect. Older Android devices may require a QR code scanner app like Google Lens. Most tablets and laptops with cameras also support QR scanning through their built-in camera software.
Is there a character limit for the WiFi password in a QR code?
QR codes can hold up to about 4,296 alphanumeric characters, so even very long WiFi passwords are not a problem. However, extremely long strings produce denser QR codes that may be harder to scan at small print sizes. In practice, WiFi passwords under 63 characters (the WPA2 maximum) work perfectly. Keep the QR code output size at 400px or above for best scanning reliability.
Does the QR code work for hidden networks?
Yes. Check the "Hidden network" option in the generator to include the hidden flag in the QR data. When a device scans the code, it will know the SSID is not broadcast and will attempt to connect directly. Note that some older Android versions may not fully support auto-connecting to hidden networks via QR — the user may need to manually confirm the connection in their WiFi settings.
Can I use WPA3 in my WiFi QR code?
Yes, select "WPA3 (SAE)" from the security type dropdown. The QR code will use the SAE encryption identifier in the WIFI protocol string. Keep in mind that the scanning device must also support WPA3 to connect. If you have a mix of older and newer devices, consider keeping your router in WPA2/WPA3 transition mode and generating the QR code with WPA/WPA2 selected for maximum compatibility.
Is my WiFi password safe? Does it get sent to a server?
No data leaves your browser. QRSansar generates QR codes entirely on your device using client-side JavaScript. Your network name, password, and all other inputs stay in your browser and are never transmitted, stored, or logged anywhere. You can verify this by disconnecting from the internet and using the generator — it works fully offline.
