What Is a WiFi QR Code?

A WiFi QR code encodes your network name (SSID), security protocol, and password in a standardized string format that smartphones recognize automatically. When scanned, the device offers to connect to the network without the user typing anything. This eliminates the common frustration of dictating long or complex passwords to guests.

The encoded data follows the format:

WIFI:T:WPA;S:MyNetwork;P:MyPassword;H:false;;

Where T is the security type (WPA, WEP, or nopass), S is the SSID, P is the password, and H indicates whether the network is hidden. Special characters in the SSID or password (semicolons, colons, commas, backslashes) are automatically escaped by this tool.

How to Create a WiFi QR Code

Generate a scannable WiFi QR code in six steps.

  1. Enter network name (SSID): Type your WiFi network name exactly as it appears in your device's network list. The SSID is case-sensitive.
  2. Select security type: Choose WPA/WPA2/WPA3 (most common for modern routers), WEP (legacy devices only), or None for open networks.
  3. Enter password: Type your WiFi password exactly. This field is hidden when "None" is selected since open networks have no password.
  4. Mark if hidden: Check "Hidden Network" only if your router is configured to not broadcast the SSID.
  5. Customize appearance: Adjust the QR code size (128px to 512px) and choose foreground and background colors. Keep high contrast for reliable scanning.
  6. Generate and download: Click "Generate WiFi QR Code", then download the PNG image or click "Print" to send it directly to your printer.

How to Use WiFi QR Codes

On iOS (iPhone/iPad):

  1. Open the Camera app.
  2. Point the camera at the QR code.
  3. Tap the notification that appears at the top.
  4. Tap "Join" to connect to the WiFi network.

On Android:

  1. Open the Camera app or a QR code scanner.
  2. Point the camera at the QR code.
  3. Tap the notification or popup that appears.
  4. Confirm to connect to the WiFi network.

Tips:

  • Print the QR code and place it near your router or in guest areas.
  • Include the WiFi QR code in welcome packets for Airbnb or rental properties.
  • Use it at offices, cafes, or events to simplify guest WiFi access.
  • Laminate printed QR codes for durability.

WiFi QR Code Examples

Here are common scenarios where WiFi QR codes save time and reduce support requests.

  • Home guest network: SSID SmithFamily_Guest, security WPA2, password Welcome2024!. Print the QR code on a small card and place it in the guest bedroom. Visitors scan once and connect instantly without asking for the password.
  • Coffee shop or restaurant: SSID CafeWiFi, security WPA2, password CoffeeLovers. Print the QR code on table tents or laminated cards. Eliminates the need for staff to repeat the password to every customer.
  • Airbnb or vacation rental: SSID BeachHouse_5G, security WPA3, password Sunset#Beach42. Include the QR code in the welcome packet alongside check-in instructions. Guests connect in seconds even if the password is complex.
  • Office conference room: SSID AcmeCorp_Meeting, security WPA2, password MeetingRoom!2024. Display the QR code on a framed sign in each meeting room so visitors and contractors can connect without IT support.

WiFi QR Code Security Best Practices

WiFi QR codes store the network password in plain text within the QR code data. Anyone who scans the code gains the same network access as any other connected device. Follow these practices to share WiFi safely.

  • Use a dedicated guest network: Most modern routers support guest networks that are isolated from your main network. Share only the guest network via QR code so visitors cannot access printers, NAS devices, or other local resources.
  • Change the guest password quarterly: Rotate the guest network password every 3 months and regenerate the QR code. This limits access for anyone who may have scanned the code previously.
  • Control physical placement: Only display printed QR codes in areas accessible to trusted individuals. Avoid placing them on exterior-facing windows or public bulletin boards.
  • Enable client isolation on the guest network: This router setting prevents devices on the guest network from communicating with each other, adding an extra layer of security.
  • Monitor connected devices: Regularly check your router's admin panel for unknown devices. Most routers show a list of connected clients with MAC addresses and hostnames.
  • Client-side generation: This tool generates the QR code entirely in your browser using JavaScript. Your SSID and password are never transmitted to any server.

Frequently Asked Questions

A WiFi QR code encodes your network name (SSID), security type, and password in a standardized format: WIFI:T:WPA;S:NetworkName;P:Password;H:false;;. When a smartphone camera scans this QR code, the operating system recognizes the WiFi configuration and offers to connect automatically. The user does not need to manually type the network name or password. This format is supported by iOS 11+, Android 10+, and most modern QR scanner apps.

This generator supports three security types: WPA/WPA2/WPA3 (the most common and recommended option for home and business networks), WEP (an older, less secure protocol still used on some legacy devices), and None (for open networks with no password). If your router uses WPA2 or WPA3, select the WPA option as the QR code format is the same for all WPA variants.

WiFi QR codes store the network password in plain text within the QR code data. Anyone who scans the code can see the password and connect to your network. For security, create a separate guest network with a unique password for QR code sharing instead of sharing your main network credentials. Change the guest network password periodically and regenerate the QR code. Place printed QR codes only in locations accessible to trusted individuals.

The Hidden Network checkbox sets the hidden flag in the WiFi QR code data. When enabled, the scanning device knows that the SSID is not broadcast and will attempt to connect even if the network does not appear in the list of available networks. Check this option only if your router is configured to hide the SSID. For most home and business networks where the SSID is visible, leave this unchecked.

Place printed WiFi QR codes near your router, at the entrance or reception area, on the front desk of a hotel or office, in Airbnb welcome packets, or on cafe and restaurant tables. Laminate the printed code for durability. Ensure the QR code is at least 2 cm x 2 cm for reliable scanning. For outdoor use, consider using weather-resistant materials and a larger print size.

Yes. WiFi QR codes store the password at the time of generation. If you change your WiFi password, the old QR code will no longer work because it contains the previous password. You need to regenerate and reprint the QR code with the new password. This is another reason to use a dedicated guest network for QR code sharing, as you can change the guest password without affecting your main network devices.
