How to Share a Wi-Fi QR Code: A Complete Guide for Android, iOS, and Routers

Sharing Wi-Fi access via QR code is a quick and secure way to share internet access with guests, colleagues, or family members without having to verbalize the password. Instead of dictating a complex combination of characters (which is easy to forget or mix up), simply scan the code with your smartphone's camera. But how exactly do you generate such a code? Where can you find it on your router? And is it possible to create a QR code manually if your device doesn't support this feature?

In this article, we will look at all the current methods for transmitting a Wi-Fi QR code - from built-in tools Android 10+ And iOS 11+ to online generators and settings for popular routers (TP-Link, ASUS, Keenetic). You'll also learn how to protect your code from hackers and what to do if the QR code won't scan. Let's start with the simplest option—automatic code generation on your smartphone.

1. How to generate a Wi-Fi QR code on Android without third-party apps

Modern versions of Android (starting from Android 10) can create QR codes for connecting to Wi-Fi directly in the network settings. This method works on most devices. Samsung, Xiaomi, Google Pixel and other brands. The main requirement is that the phone must already be connected to the network you want to share.

Instructions:

  • 📱 Open Settings → Wi-Fi (or Network and Internet → Wi-Fi).
  • 🔍 Find your network in the list and tap on its name (not on the switch!).
  • 🖼️ In the window that opens, find the button Share (or QR code, Share).
  • 🔒 Confirm the action with your fingerprint, pattern, or PIN.

After this, a QR code will appear on the screen, which can be scanned with another device. On some firmware versions (for example, MIUI from Xiaomi) The code is automatically updated every 30 seconds for security. If you have an older version of Android or a custom ROM, this method may not work—proceed to the next section.

⚠️ Please note: Some manufacturers (eg. Huawei) block QR code generation for guest networks. If you use the function Guest network On the router, first connect to the main network.

2. Generate a Wi-Fi QR code on iPhone (iOS 11 and later)

On iPhone There is no built-in QR code generation function for Wi-Fi, but there is a workaround via Share Password functionIt works between devices. Apple (iPhone, iPad, Mac) and requires both devices to be in the same ecosystem. If you need to share code with Android or a PC, use third-party apps (more on that in Section 4).

How to transfer access between Apple devices:

  • 🍎 Connect both devices to the same network iCloud (your iPhone and the device you are granting access to).
  • 🔗 On the receiving device, select the Wi-Fi network you want to connect to.
  • 📱 A pop-up window will appear on your iPhone with an offer Share password. Tap Share.
  • ✅ The password will be transferred automatically, without displaying the QR code.

To generate a full QR code (for example, to print it out and hang it on the wall), use online generators or applications like QR Code Generator from App StoreThey allow you to generate a code even without a network connection—just enter the network name and password manually.

networksetup -getairportnetwork en0 | awk -F': ' '/Current Wi-Fi Network/{print $2}' | xargs -I {} qrencode -o wifi_qr.png "WIFI:S:{};T:WPA;P:$(security find-generic-password -wa "{}");;"

The code will be saved to a file. wifi_qr.png on the desktop.-->

3. Where to find the Wi-Fi QR code in the router settings

Many modern routers (TP-Link, ASUS, Keenetic, MikroTik) generate a QR code for connection directly in the web interface. This is convenient if you want to print the code and post it in a public place (for example, a cafe or office). Let's look at where to find this feature on popular models.

Manufacturer Path to QR code Notes
TP-Link General Settings → Wireless → Wi-Fi QR Code Available on models with firmware Archer C6 and newer.
ASUS Wireless Network → QR Code (tab on the right) On some models, the code is updated when the password is changed.
Keenetic Wi-Fi → Main network → QR code icon next to the name Supports guest network code generation.
MikroTik Wireless → Security Profiles → Select Profile → QR Code Manual creation of a security profile is required.

If your router does not support QR code generation, you can use an alternative method:

  1. Copy the network name (SSID) and the password from the router settings.
  2. Use online generator or a code generation app.
⚠️ Attention: On some routers (for example, Zyxel Keenetic) The QR code may contain data for connecting to guest network, even if you generated it for the main one. Check the network name (SSID) in the code before use.

4. Online QR code generators for Wi-Fi: TOP 5 services

If neither your smartphone nor your router can generate a QR code, online services can help. They allow you to create a code manually by specifying:

  • 📡 Network name (SSID);
  • 🔐 Encryption type (WPA/WPA2 or WPA3);
  • 🔑 Password.

The best services for generating:

Service Link (for search) Peculiarities
QR Code Generator qrcode-generator.com Supports WPA3, export to PNG/SVG.
QR Stuff qrstuff.com You can add a logo to the center of the code.
ZXing Project zxing.app Open source, no fluff.
WiFi QR wifi-qr.com Specialized service for Wi-Fi only.

Important: Never enter your Wi-Fi password on untrusted websites. Use only trusted services with the HTTPS protocol (the 🔒 icon in the address bar). Once generated, the code can be saved as an image or printed.

Do not send the code in clear text via instant messengers.

Delete the code after use (if it is temporary)

Check that the code contains the correct SSID (network name)

Do not generate code on public computers-->

5. How to scan a Wi-Fi QR code on different devices

Most modern devices support scanning QR codes to connect to Wi-Fi. Let's look at how to do this on different platforms.

Android

On most smartphones, simply open the camera and point it at the code. A notification will appear prompting you to connect. If this doesn't happen:

  1. Open the app Google Lens (or Google Assistant → Lens).
  2. Point your camera at the QR code.
  3. Tap on the pop-up notification Connect to Wi-Fi.

iPhone (iOS 11+)

On iPhone scanning works through the standard application Camera:

  1. Open camera and point it at the QR code.
  2. A notification will appear at the top of the screen. Wi-Fi network - tap on it.
  3. Confirm the connection.

Windows 10/11

On a PC, you will need a third-party application for scanning, for example:

  • 🖥️ QR Code Scanner (from Microsoft Store);
  • 🌐 Online scanners (for example, WebQR).

After scanning, the code will automatically connect you to the network if your Wi-Fi adapter drivers support this feature.

MacOS

On MacBook You can scan the code through the app Camera (on the menu File → Import from iPhone, if you have iPhone) or use QR Journal from App Store.

⚠️ Note: If the device does not connect after scanning, check:
  • 🔄 The entered password is correct (sometimes the QR code contains outdated data).
  • 📶 Wi-Fi signal strength (you may be too far from the router).
  • 🔒 Encryption type (if the router uses WPA3, and the device only supports WPA2, the connection may not work).

6. Security: How to protect your Wi-Fi QR code

A QR code for Wi-Fi is convenient, but it's not always secure. If the code falls into the wrong hands, others can connect to your network. Here's how to minimize the risks:

  • 🔄 Change your password regularly from Wi-Fi (once every 3-6 months).
  • 🚫 Do not post the code in public places (for example, on social networks or instant messengers).
  • 🛡️ Use a guest network for temporary guests (configure it in the router).
  • 🔍 Check connected devices in the router settings (DHCP → Clients).

If you suspect that someone has connected to your network, follow these steps:

  1. Go to your router settings (usually at 192.168.1.1 or 192.168.0.1).
  2. Go to the section Wireless Mode → Client Statistics (or similar).
  3. Check the list of connected devices. Unknown MAC addresses can be blocked.
  4. Change your Wi-Fi password in the section Security.

For additional protection, enable the following on your router:

  • 🔒 MAC address filtering (Allow only trusted devices to connect).
  • 🛡️ WPA3 instead of WPA2 (if all your devices support it).
  • 🔄 Disabling WPS (This protocol is vulnerable to hacking).

7. Common problems and their solutions

Sometimes a Wi-Fi QR code doesn't work or behaves strangely. Let's look at common issues and how to fix them.

Problem Possible cause Solution
The QR code is not scanned. Poor print or screen quality Try displaying the code on a different screen or increase the contrast.
There is a connection, but no internet Router restrictions (e.g. MAC filtering) Check your settings Client filtering in the router.
The code leads to another network Error generating (invalid value specified) SSID) Please regenerate the code, checking the data carefully.
Android doesn't prompt to connect after scanning There is no support for this function on older versions. Please update your firmware or use a scanner app (eg. QR & Barcode Scanner).

If the problem is not resolved, try:

  • 🔄 Reboot the router (sometimes helps with problems in IP address distribution).
  • 📱 Reset network settings on smartphone (Settings → System → Reset → Reset Wi-Fi).
  • 🔧 Update your router's firmware (older versions may not work correctly with QR codes).
What to do if the QR code contains a virus?

Theoretically, a QR code could redirect to a phishing site, but this is unlikely for Wi-Fi—the code only contains network data. However, if you are redirected to a strange website after scanning, it's a fake code. Never enter usernames or passwords on websites opened after scanning a QR code!

FAQ: Answers to Frequently Asked Questions
