Modern technologies have greatly simplified the process of connecting to wireless networks, and one of the most convenient tools has become the QR code. Instead of dictating a complex password of numbers and letters to guests or searching for a sticker on the bottom of the router, you can simply hold your smartphone camera up to it. However, situations often arise when you need to quickly access the network, but the visual code is nowhere to be found. Users wonder, Where can I find a Wi-Fi QR code?, if it is not printed on the equipment body.
The answer depends on what specific device you're using to share your internet connection and what gadget you want to connect. In most cases, this code is generated programmatically or physically placed on a label, but its location may not be obvious. There are methods for Android, iOS and even Windows-based computers that can generate or display the required barcode.
In this article, we'll cover all the possible options for finding and creating a QR code for network authorization. You'll learn how to find hidden settings in the router interface, use smartphone system functions, and utilize specialized utilities. This knowledge will save you time and eliminate the need to manually enter passwords every time.
Find the code on the router body and in the documentation
The most obvious, but often overlooked, way is a physical inspection of the equipment. Network equipment manufacturers such as TP-Link, Asus or Keenetic, a factory-installed QR code is often placed on the bottom of the device. This code typically contains the initial connection information to the Wi-Fi network with the factory-installed name and password. If you've never changed your router's security settings, simply turn it over and look for a sticker labeled "QR Code" or an image of a square barcode.
⚠️ Note: If you've changed the network name (SSID) or password in the router settings, the factory QR code on the router case will not work. It only works with the factory default settings.
In some cases, the sticker may be worn out, damaged, or located in a hard-to-reach place, such as under a removable antenna. It's also worth checking the original packaging or the user manual that came with the device. It may contain a separate insert with a quick setup code. If the sticker is illegible, you'll need to use software-based access recovery methods.
Newer router models typically feature a WPS function, sometimes accompanied by a QR code. Check the back panel for a button labeled as such. Although the button itself doesn't generate an image, modern router management interfaces often feature a "Quick Connection" section where you can regenerate this code. This is especially true for devices released after 2020.
Generating a QR code in Android 10 and later
Owners of smartphones based on the operating system Android are in the most advantageous position. Starting with Android 10, the QR code generation feature for the current Wi-Fi network is built right into the system settings. You don't need to install third-party apps or have root access. Simply be connected to the network whose password you want to share.
To receive the code, follow these steps:
- 📱 Open Settings and go to the "Wi-Fi" or "Connections" section.
- 🔗 Click on the name of the network you are connected to or on the gear icon next to it.
- 👁️ Select the "Share" or "QR code" option (the location depends on the manufacturer's shell, for example, OneUI or MIUI).
- 🔐 Enter your screen unlock PIN or place your finger on the scanner to confirm.
After confirmation, a large QR code will appear on the screen. It can be scanned with the camera of another device for instant connection. It's worth noting that a text password is often written underneath the code image, which can be copied or rewritten. This works on the vast majority of modern smartphones, including Samsung, Xiaomi, Honor And Google Pixel.
If the code isn't displayed using standard tools, check for system updates. In some custom firmware versions, this feature may be hidden in the "Advanced" menu. It's also worth remembering that this method may not work for guest networks or corporate networks with web portal authentication, as they use a different security protocol.
How to view a code on iPhone (iOS 18 and later)
Long time users iPhone Many users couldn't easily view the password or QR code for the network they were connected to. However, with the release of iOS 18, Apple introduced a long-awaited feature that allows you to generate a QR code directly from Wi-Fi settings. This eliminates the need for complex workarounds or configuration apps.
The process of getting the code on iOS 18 looks like this:
- 🍎 Open "Settings" and go to the "Wi-Fi" section.
- ℹ️ Click the blue information icon (the letter "i" in a circle) next to your active network.
- 📄 Select "QR code" or "Show QR code".
- 👤 Complete biometric authentication (Face ID or Touch ID).
After successful verification, the system displays a square barcode that can be scanned with any camera. This solution significantly simplifies life for Apple ecosystem users. Previously, the only option was to use Shortcuts or third-party apps from the App Store, which required additional steps and was not always reliable.
⚠️ Note: On iOS versions below 18, the native QR code viewing feature may not be available. In this case, iPhone owners will have to use a computer or Android smartphone to generate the code, or enter the password manually.
It's important to note that this feature only works for networks your phone is already connected to or has previously saved. For hidden networks (hidden SSID), code generation may not be available for security reasons. Make sure your device is updated to the latest available software version.
Using the router interface to receive data
If mobile devices aren't available or are too far away, you can turn to the signal source—the router itself. Almost all modern models have a web interface accessible through a browser. By logging into the control panel, you can not only view the password, but also, in some models, find a pre-made QR code for guests.
To enter the interface, follow these steps:
- Connect to the router via cable or Wi-Fi.
- Open your browser and enter the router's IP address in the address bar (usually
192.168.0.1or192.168.1.1). - Enter the administrator login and password (often by default)
admin/admin, if you haven't changed them). - Go to the "Wireless" or "Guest Network" section.
In router interfaces Keenetic, MikroTik or Tenda There's often a separate "System Information" or "Quick Start" tab that displays a QR code for connecting mobile devices. If you don't have a ready-made image, you can copy the password from the same menu. Knowing the exact password and encryption type (usually WPA2-PSK), you can generate the code yourself using online services.
Some advanced models support a "Guest Wi-Fi" feature with a separate QR code that can be updated on a schedule. This is ideal for cafes or offices that need to regularly change access for visitors. Check your model's documentation to see if this feature is available in the "Security" or "Services" section.
What should you do if you forgot your router password?
If you've changed the administrator password and forgotten it, the only solution is to reset the router to factory settings. To do this, press and hold the Reset button on the device for about 10-15 seconds (until the indicators flash). After this, the router will reset to the default login and password listed on the sticker.
Create a QR code using a computer (Windows and macOS)
When you don't have a smartphone with the required functionality, a computer comes to the rescue. Operating systems Windows 10/11 And macOS Wi-Fi networks don't have a built-in "Show QR code" button, but they do allow you to find the password of a saved network. Once you know the password, you can use any online generator or specialized software.
In Windows, you can find the password using the command line. Open the terminal (cmd) as administrator and enter the command to view the network profile:
netsh wlan show profile name="Network_Name" key=clearYour password will be displayed in the "Key Content" line. After copying it, go to any QR code generator website, select "Wi-Fi," enter the network name (SSID), and the password you received.
On macOS The process is even simpler if you have the latest version of the operating system. Open Keychain Access, find your Wi-Fi network in the list, double-click it, and check the "Show password" box. The system will prompt you to enter your Mac account password, after which the Wi-Fi password will be displayed in the text field.
| Method | Necessary conditions | Complexity | Security |
|---|---|---|---|
| Sticker on the router | Factory settings | Low | High |
| Android (Settings) | Android 10+ | Low | High |
| iPhone (iOS 18) | iOS 18+ | Low | High |
| Command Prompt (Win) | Admin rights | Average | Average |
Using third-party online generators is safe as long as you don't share sensitive data, but the image generation process itself occurs on a remote server. For maximum privacy, it's best to use offline programs or built-in OS features.
Third-party applications and utilities
If built-in tools are not available, there are many apps available in stores. Google Play And App Store, which specialize in managing Wi-Fi connections. Programs such as WiFi Map, Instabridge or simple QR code generators can create an image based on the data you enter.
When choosing an app, pay attention to the permissions it requests. Many utilities require access to geolocation and contact lists, which are unnecessary for simple code generation. Choose proven solutions with high ratings and numerous reviews to avoid installing malware.
☑️ App Security Check
There are also scanner apps that can not only read but also create codes. Some of them have a "history" feature, allowing you to quickly find previously used codes for your home network. However, remember that storing passwords in plaintext in third-party apps can pose a risk if your phone is hacked.
Frequently Asked Questions (FAQ)
Is it possible to find out the QR code if I have never been connected to this network?
No, the QR code contains an encrypted password. If you don't know the password and don't have physical access to the router (where it might be written), it's impossible to generate a working code. You'll need to obtain the password from the network owner.
Does QR code work if the network is hidden (Hidden SSID)?
Technically, it's possible to generate a code, but standard smartphone cameras may not recognize the command to connect to a hidden network via a QR code. Connecting to hidden networks usually requires manually entering the name and password in the Wi-Fi settings.
Is it safe to place a Wi-Fi QR code in a public place?
Place code from guest network It's safe. However, never place a QR code from your main home network with access to personal files and a smart home device. Attackers can intercept traffic or gain access to local devices.
What should I do if the camera doesn't read the code from the screen?
Increase the brightness of the screen displaying the code. Make sure the camera lens is clean. Also, try changing the distance: move the phone closer or further away. If the code is damaged (due to compression artifacts), find the original in the settings again.
