How to Create a WiFi QR Code?


Learn how to create a WiFi QR code so people can connect to a wireless network more easily without manually typing the network name and password.

Sharing a WiFi network with guests can be inconvenient when they have to find the network name, type a long password, and carefully check every character.

A WiFi QR code provides a simpler way to share wireless network information. When a compatible smartphone scans the QR code, the device can recognize the WiFi details and may offer an option to connect to the network.

WiFi QR codes can be useful in homes, offices, restaurants, hotels, cafés, events, classrooms, coworking spaces, and other places where people regularly need temporary or guest WiFi access.

In this guide, you'll learn what a WiFi QR code is, what information it contains, how to create one, how to test it, and how to share it safely.

Quick answer: To create a WiFi QR code, enter your network name (SSID), select the correct security type, enter the password if required, and generate the code. Scan it with a compatible smartphone to test it before downloading or printing it.

What Is a WiFi QR Code?

A WiFi QR code is a QR code that contains information needed to identify and connect to a wireless network.

Depending on the network configuration and QR code format, this information can include the WiFi network name (SSID), security type, password, and whether the network is hidden.

Instead of manually entering those details, a compatible device can scan the QR code and use the encoded information to assist with connecting to the network.

How Does a WiFi QR Code Work?

The process is simple:

  1. The WiFi network information is entered into a QR code generator.
  2. The information is converted into a QR code.
  3. The QR code is displayed or printed.
  4. A compatible smartphone scans the QR code.
  5. The device recognizes the encoded WiFi information.
  6. The user can follow the device's connection prompt when supported.

The exact connection experience can vary depending on the smartphone, operating system, security configuration, and network settings.

What Information Does a WiFi QR Code Contain?

A WiFi QR code can contain several pieces of information about the wireless network.

  • Network name (SSID) — the name of the WiFi network.
  • Security type — the security configuration used by the network.
  • Password — the wireless network password when one is required.
  • Hidden network setting — indicates whether the WiFi network is hidden.

It is important to enter these details accurately. An incorrect network name, password, or security setting can prevent the device from connecting.

How to Create a WiFi QR Code

Step 1: Find Your WiFi Network Name

First, identify the name of the wireless network you want to share. This is commonly called the SSID.

Make sure you use the exact network name, including capitalization and any spaces or special characters.

Step 2: Identify the WiFi Security Type

Select the security type used by your wireless network. Depending on the network and QR code generator, available options may include WPA/WPA2/WPA3, WEP, or an open network without a password.

If you are unsure which security type your router uses, check your router's settings or documentation before creating the QR code.

Step 3: Enter the WiFi Password

If your network is password-protected, enter the exact WiFi password.

Check the password carefully before generating the QR code. A single incorrect character can prevent a device from connecting.

Step 4: Choose Whether the Network Is Hidden

If your WiFi network is configured as a hidden network, enable the hidden-network option in the QR code generator.

For a normal visible WiFi network, leave the hidden-network option disabled.

Step 5: Generate Your WiFi QR Code

Once your network details are entered, generate the QR code.

Step 6: Scan and Test the QR Code

Before displaying or printing the QR code, test it with a compatible smartphone.

Scan the QR code and check whether the device recognizes the WiFi network and provides the expected connection option.

If the connection does not work, recheck the SSID, security type, password, and hidden-network setting.

Step 7: Download or Display the QR Code

After confirming that the QR code works, download it and place it somewhere convenient for your guests or customers.

You could display it on a small sign, reception desk, restaurant table, office notice board, guest room, or other appropriate location.

Which WiFi Security Types Can a QR Code Support?

WiFi QR code formats can support different network configurations depending on the generator and device.

WPA / WPA2 / WPA3

These are common security configurations for modern wireless networks. Select the option that corresponds to your network's actual configuration.

WEP

Some older wireless networks may use WEP. If your network uses WEP, select the corresponding option when supported by the QR code generator.

Open Network

An open WiFi network does not require a password. If you are creating a QR code for an open network, select the appropriate open or no-security option.

Where Can You Use a WiFi QR Code?

WiFi QR codes can be useful anywhere visitors need convenient access to a wireless network.

  • Homes and apartments
  • Guest rooms
  • Hotels and accommodations
  • Restaurants and cafés
  • Offices
  • Reception areas
  • Coworking spaces
  • Classrooms
  • Events and conferences
  • Waiting areas
  • Retail stores

WiFi QR Codes for Businesses

Businesses can use WiFi QR codes to make guest network access easier.

For example, a café can place a WiFi QR code near the counter, while a hotel can provide one in a guest room or reception area. An office can also use one to help visitors connect to a dedicated guest network.

For security reasons, businesses should consider using a dedicated guest WiFi network rather than sharing credentials for a private internal network.

Tips for Printing a WiFi QR Code

A WiFi QR code should be easy to see and scan.

  • Use a clear, high-contrast design.
  • Leave enough clear space around the QR code.
  • Avoid placing the QR code over a busy background.
  • Print it large enough for the expected scanning distance.
  • Test the actual printed QR code before displaying it.

If the QR code will be placed somewhere with frequent handling, consider protecting the printed sign from damage or excessive wear.

Is It Safe to Share a WiFi QR Code?


A WiFi QR code can make sharing network access convenient, but remember that the QR code may contain the network password or other connection information.

Only display a WiFi QR code where you are comfortable sharing access to that particular network.

For public-facing displays, use a dedicated guest WiFi network and avoid sharing credentials for your private home or business network.

For businesses and other organizations, a separate guest network can help keep visitors away from private devices, systems, and internal resources.

Avoid publishing a QR code containing private WiFi credentials on public websites or other locations where unintended people could access it.

Why Isn't My WiFi QR Code Working?

If a WiFi QR code does not work as expected, check the following:

  • Verify the WiFi network name (SSID).
  • Check that the password is correct.
  • Confirm the selected security type.
  • Check the hidden-network setting.
  • Make sure the QR code is clear and undamaged.
  • Try scanning from a different distance or angle.
  • Test with another compatible smartphone if available.

Different smartphones and operating systems can also provide different QR scanning and WiFi connection experiences.

Why Use a WiFi QR Code Instead of Sharing the Password Manually?

The main benefit is convenience. A long WiFi password can be difficult to type correctly, especially when it contains uppercase letters, numbers, or special characters.

A QR code allows the network information to be represented visually, making it easier for compatible devices to read the information without requiring the user to manually type every character.

Other QR Code Tools You Can Use

QR Code Tools provides several browser-based QR utilities for different types of information.
