Modern technology allows you to share internet access with just one touch of a screen, but users often face situations where they need to share a password with guests or connect to the network on a device that doesn't have an NFC module. Apple People often wonder how to find or generate a visual password for quick authorization, especially if the standard Bluetooth "Share Password" function does not work or the receiving device is running Android.
In the operating system iOS The process of creating such code is not always obvious, since Apple does not put this function on the main settings screen by default in older versions, although in iOS 18 The situation has changed dramatically. You'll need to use the system's built-in capabilities or third-party solutions to convert stored network data into a readable pattern that can be scanned with any smartphone camera.
In this article, we'll take a detailed look at all the current code generation methods, from native features of the latest firmware versions to creating automated scripts through the Commands app. You'll learn how to quickly grant access to Wi-Fi networks guests, avoiding the need to dictate complex character combinations or show a screen with the entered password.
Native feature in iOS 18 and later
With the release of the update iOS 18 company Apple has finally implemented the long-awaited feature that allows you to instantly generate a QR code directly in the wireless network settings menu. This solution eliminates the need for third-party apps or complex scripts, making the process as simple and secure as possible for the average user.
To use this feature, you need to open the Settings app and go to the section Wi-FiFind the network you are already connected to or have used before and click the blue information icon (i) To the right of the access point name. In the menu that opens, immediately below the network name and connection status, you'll see a special button with a QR code.
Pressing this button instantly generates a unique pattern on your device's screen. Guests only need to point their smartphone camera at your device's display. iPhoneto automatically connect to the internet. This feature is especially convenient in offices or cafes where new visitors need to log in frequently.
⚠️ Attention: The built-in QR code generator feature is only available on devices with the updated operating system version 18 and above. On older versions iOS This menu item may not be available and will require using the alternative methods described below.
Using Shortcuts for Older iOS Versions
For device owners who don't plan to update to the latest version iOS, or for those who prefer to have a permanent widget on their desktop, the ideal solution would be to use the system application “Commands” (Shortcuts). This method allows you to create a personalized shortcut that generates a code for any network stored in your phone's memory.
The setup process requires several sequential steps. First, you need to download a ready-made shortcut template from a trusted source or create one manually, adding the "Select Wi-Fi network" action and the "Show QR code" action. After adding the shortcut to the library, it will appear in the Shortcuts app and can be displayed on the home screen as a separate icon.
When you launch the created shortcut, the system will prompt you to select one of your previously used networks. Once selected, an image will instantly appear on the screen, ready for scanning. This solution is the most flexible, as it allows you to create separate icons for a guest network, your main work network, or even a smart home network.
- 📱 Open the Shortcuts app and go to the Gallery tab or use search.
- 🔍 Find the "Wi-Fi QR" or "Wi-Fi Connect" command from trusted authors.
- ✅ Add the command and grant the necessary permissions to access network data.
- 🏠 Place a shortcut on your desktop for quick access in one tap.
☑️ Checking the readiness of the shortcut
Manual setup via the Teams app
If you prefer full control over the tools you create or don't trust ready-made templates from the internet, you can build the code generation functionality yourself. It takes no more than two minutes, but it will give you an understanding of exactly how iPhone processes connection requests.
Launch the Shortcuts app and create a new shortcut. In the action search, enter "Wi-Fi" and select the "Select Wi-Fi network" action. Next, add the "QR code" action, which converts the selected network data into a graphic image. Enter the result from the previous step as the input for the code.
The final step is to add the "Show Result" or "View" action to display the generated image full-screen. Save the command under a descriptive name, such as "My Wi-Fi Code." Now, every time you launch the system, you'll be prompted to select a network (if there are multiple) and display the current code.
⚠️ Attention: When creating commands manually, ensure you don't add unnecessary steps that might require confirmation. For maximum guest performance, the command should execute automatically after a single click.
Secret command parameters
In the advanced settings of the QR Code action, you can change the pixel size and error correction level, which is useful for printing the code on paper or a business card.
Third-party apps from the App Store
When built-in tools seem too complicated or require time to set up, specialized apps from the store come to the rescue. App StoreThere are many free utilities that specialize exclusively in generating QR codes for various types of data, including wireless network parameters.
Applications such as Qrafter or QR Reader for iPhone, have a simple interface: you select the data type “Wi-Fi”, enter the network name (SSID) and a password, and the app generates an image. Some apps can even scan codes from other screens, allowing you to quickly verify the correctness of the generated key.
The main advantage of third-party software is the ability to save a history of generated codes and export them as images for printing or sending via instant messaging. This is convenient for administrators who need to grant access to dozens of devices.
| Application | License type | Advertising | Preserving history |
|---|---|---|---|
| Qrafter | Freemium | Eat | Yes |
| QR Reader | For free | Eat | Yes |
| Visual QR | Paid | No | Yes |
| Commands (iOS) | For free | No | No |
Display and encoding issues
When generating codes for Wi-Fi networks, problems with character encoding often arise, especially if the password uses special characters or symbols of national alphabets. Standard Wi-Fi Alliance strictly regulates the format of the line, and the slightest deviation can lead to the scanning device not being able to recognize the network.
The most common error is using the wrong prefix in the data string. For correct operation, the code should start with WIFI:S:, followed by the network name, then ;T: with the encryption type (usually WPA or WEP), P: with a password and end with a semicolon. If you're creating the code manually or using a script, make sure the syntax is correct.
It is also worth considering that some older models Android-smartphones may not correctly read codes generated on iPhoneIf your password uses emoji or rare Unicode characters, it's recommended to temporarily simplify your password to alphanumeric format.
Security and Guest Access
Using QR codes to share internet access carries not only convenience but also certain security risks. Anyone who receives an image of the code (for example, by taking a screenshot) gains full access to your network, and it will be impossible for them to change the password remotely without changing the key for all devices.
To minimize risks, it is recommended to use the "Guest Network" feature, which is available in most modern routers. This feature creates a separate SSID, isolated from your main local network where personal computers, NAS storage and smart devices are located.
By generating a QR code specifically for your guest network, you protect your data from prying eyes. Even if the code falls into the wrong hands, they won't be able to access your files or CCTV cameras while within range.
- 🔒 Enable the guest network in the router settings via the web interface.
- 🚫 Set a time limit or a limit on the number of connected devices.
- 🔄 Change your guest network password regularly if access is granted on a regular basis.
- 👁️ Do not leave the screen with the QR code on unattended in public places.
⚠️ Attention: Router interfaces and security settings may vary depending on the model and firmware. Always ensure that AP Isolation is enabled on the guest network to prevent guest devices from seeing each other.
Frequently Asked Questions (FAQ)
Is it possible to view a Wi-Fi QR code on an iPhone without installing apps?
Yes, if you have an operating system installed iOS 18 If you have an iPhone or iPad running iOS 11 or later, the feature is built into your Wi-Fi settings. On older versions, you can use the system Shortcuts app, which is standard on all Apple devices and doesn't require downloading from the App Store unless it's been previously uninstalled.
Why can't the camera see the QR code on my iPhone screen?
This could be due to several reasons: screen brightness is too low, the scanner's camera lens is dirty, or the code size is incorrect. Try zooming in or reducing the distance between the devices. Also, make sure the screen isn't covered with a protective film with a strong anti-glare coating that could distort contrast.
Does this method work for 5GHz networks?
Yes, the signal frequency (2.4 GHz or 5 GHz) does not affect the QR code's functionality. The code only contains the network name (SSID) and password. If your router broadcasts two networks with different names for different frequencies, you will need to generate a separate code for each of them or combine them under a single name (SSID) in the router settings.
Is it possible to print a QR code for the office?
Absolutely. After taking a screenshot of the generated code, you can print the image. For office spaces, it's recommended to laminate the printout and display it in a visible location, along with a label indicating the network name so visitors know which network they're connecting to.
