Connecting to Wi-Fi via QR Code on Android: A Complete Guide

Connecting to Wi-Fi via QR code on smartphones Android — is a quick and convenient way to avoid manually entering complex passwords. This is especially useful for guest networks, where the password may consist of a random set of characters, or for public hotspots with limited validity. Unlike traditional methods, scanning a QR code takes only a few seconds and eliminates typing errors.

In this article, we will look at all possible ways to connect to Wi-Fi via a QR code on devices. Android — from built-in features of modern OS versions to third-party apps. You'll learn how to create your own QR code for the network, which security settings are important to check before connecting, and what to do if your smartphone doesn't recognize the code. We'll also cover the nuances of working with different versions. Android and popular manufacturers (Samsung, Xiaomi, Google Pixel and others).

Why is a QR code more convenient than manually entering a password?

The main advantage of connecting via QR code is speed and accuracyInstead of manually entering a long password (especially if it contains special characters or case-sensitive letters), simply point the camera at the code. This saves time and eliminates common typing errors.

Another plus is - versatility. The QR code can be:

  • 📱 Generate on another device (for example, on iPhone or MacBook) and scan to Android.
  • 🖨️ Print and place in a public place (cafe, hotel, airport) to quickly connect guests.
  • 🔄 Use it to transfer network settings between your devices (for example, from a smartphone to a tablet).

In addition, some modern routers (for example, ASUS, TP-Link, Keenetic) automatically generate a QR code for connecting to Wi-Fi. It can be found on a sticker on the device or in the router's web interface under Wireless network or Go to Quick Setup.

⚠️ Warning: If you connect to a public network via a QR code, check the access point name (SSID) in the settings after scanning. Attackers may post fake codes with names similar to legitimate networks (for example, "CoffeeShop_Free" instead of "CoffeeShop_Guest").

Which Android devices and versions support QR code scanning for Wi-Fi?

The ability to connect to Wi-Fi via QR code depends on the version Android and the manufacturer's shell. Here are the main options:

Android Version / Shell QR code support for Wi-Fi Notes

Step-by-step instructions: how to connect to Wi-Fi via a QR code on Android

Let's look at a universal method that works on most modern devices. If your smartphone doesn't support the built-in function, use one of the apps mentioned above.

Method 1: Built-in function (Android 10+)

Make sure your smartphone's camera is working.

Turn on Wi-Fi in Settings

Allow the Camera app to access the network (if prompted)

Check that the QR code is displayed clearly (without glare)-->

1. Open SettingsNetwork and InternetWi-Fi.

2. Click on the icon "+" (Add network) or QR code (depending on the shell).

3. Point the camera at the QR code. Hold your smartphone 10–20 cm away from the code so it's within the scanning frame.

4. After recognition, a notification with the network name will appear (SSID). Click "Connect".

5. If confirmation is required, enter your PIN or scan your fingerprint (depending on your device security settings).

On devices with One UI (Samsung) After scanning, a warning about an "unsecured network" may appear, even if the password is entered via QR code. This is an interface error; the connection will still be secure.

Method 2: Via Google Lens

If there is no QR code scanning option in your Wi-Fi settings, use Google Lens:

1. Open the app Google Photos or Google Assistant.

2. Click on the icon Google Lens (icon with a dot in a circle).

4. Confirm the connection.

⚠️ Note: Some public networks require additional authorization via a browser (for example, at hotels or airports). After connecting via QR code, a login page may open where you must enter your room number, email address, or accept the terms of use.

How to create a QR code for your Wi-Fi network?

If you want to share access to your network with guests or other devices, you can generate a QR code yourself. To do this, you'll need:

  • 📶 Network name (SSID).
  • 🔑 Password (if the network is secure).
  • 📱 A device for generating the code (smartphone, PC, or online service).

The easiest way is to use online generators, for example:

  • Qifi.org — enter the SSID and password, download the QR code.
  • QR Code Generator — select the "Wi-Fi" type, fill in the fields.

You can also generate the code directly on Android:

1. Install the application WiFi QR Code Generator (for example, from Simple Design Ltd.).

2. Enter the network name and password.

3. Select the type of protection (WPA/WPA2 or WPA3).

4. Click "Generate" and save the image or share it.

What to do if the QR code does not scan?

If your smartphone does not recognize the QR code for Wi-Fi, check the following:
