How to quickly transfer Wi-Fi from one phone to another: all the methods for 2026

Transferring Wi-Fi data between phones is a problem that every second user faces. According to statistics J’son & Partners68% of smartphone owners have at least once tried to share their home network password with guests or family members. But not everyone knows there are faster ways than dictating complex character combinations letter by letter.

In this article we will look at 7 Current Wi-Fi Transmission Methods between devices on Android And iOS, including little-known features like Wi-Fi Direct And Nearby ShareWe will pay special attention to securityWhy you shouldn't use open networks, even for temporary sharing, and how to avoid password leaks through third-party apps. You'll also learn which phone models support them. Instant Wi-Fi sharing via NFC without entering a password — a feature that many people don’t know about.

1. Wi-Fi transfer via QR code (the most universal method)

The QR code method works on all modern smartphones (from Android 10 And iOS 11) and does not require the installation of additional applications. Its main advantage is 100% password transmission accuracy, even if it contains special characters like #, $ or spaces.

How does this work:

1. A phone that is already connected to Wi-Fi generates a QR code with encrypted network data (SSID and password).
2. The second phone scans this code and automatically connects to the network.

• 📱 On Android: Open Settings → Wi-Fi, tap on your network name → select "Share" (or "QR code"). On some firmware (for example, MIUI or One UI) the option is hidden behind the "More" button (⋮).
• 🍎 On iPhone: Go to Settings → Wi-Fi, click on the icon i next to the network name → “Share password” (if the option is inactive, check if Bluetooth is turned on).
• ⚠️ Limitation: iPhone can't do it generate A QR code for Wi-Fi can only be scanned with a camera. To generate a code on iOS, you'll need a third-party app (e.g., QR Code Generator).

Make sure the first phone's screen doesn't turn off during scanning.

Turn off power saving mode - it may block the camera

Make sure Wi-Fi is turned on on the second phone (but don't connect to the network manually)

If the QR code does not scan, clean the camera lens from dirt-->

Connection speed via QR code takes 2-5 seconds — it's 10 times faster than manually entering a password. Furthermore, this method eliminates errors due to typos or incorrect character case.

2. Using NFC (for phones with support)

NFC (Near Field Communication) enables Wi-Fi data transfer by simply touching the phones togetherThis method only works if:

• 📱 Both phones support NFC (check the model specifications).
• 🔄 NFC is enabled in the settings (Wireless Networks → NFC).
• 🔒 The sending phone is already connected to Wi-Fi.

Instructions for Android (NFC for Wi-Fi transfer is not supported on iPhone):

1. Open Settings → Wi-Fi and tap on your network.
2. Select Share → NFC.
3. Place the back cover of the second phone against the back cover of the first one (where the NFC chip is located).
4. Confirm the transfer on both devices.

If NFC doesn't work:

• 🔋 Check your battery charge - if the level is below 15%, the chip may turn off.
• 📶 Make sure there are no metal objects (cases, keys) between the phones.
• 🔄 Reset NFC in settings (Network Reset → NFC Reset).

3. Share Password on iPhone (AirDrop for Wi-Fi)

Apple has implemented a convenient mechanism for transferring Wi-Fi between devices on iOS And macOSThe main condition is that both phones must be on the same Apple ID network (or in each other's contacts).

How does this work:

1. The sending phone is connected to Wi-Fi.
2. The second phone tries to connect to the same network (selects it from the list).
3. On the first phone, a pop-up window appears asking you to "Share Password".
4. After confirmation, the second phone is automatically connected.

Why might the function not work?

If Bluetooth or Wi-Fi is disabled on your iPhone, the transfer is blocked.

The devices must be located no more than 10 meters away.

The receiving phone must have Family Sharing enabled (if the devices are not on the same Apple ID).

Limitations of the method:

• ❌ Doesn't work between iPhone And Android.
• ❌ Requires iOS 11 or newer.
• ⚠️ If the sending phone has Screen Time enabled with restrictions on wireless networks, the transfer may be blocked.

4. Transfer via Bluetooth (for older phones)

If your phones don't support NFC or QR codes, you can use BluetoothThis method is slower, but reliable for devices older than 5 years.

Step-by-step instructions:

1. Turn on Bluetooth on both phones (Settings → Connections → Bluetooth).
2. Pair the devices (find the second phone in the list and confirm the password).
3. On the sending phone, open a file transfer app (e.g. Files by Google or ShareIt).
4. Select the "Send Wi-Fi Data" option (in some apps it's called "Share Network").
5. Accept the file on the second phone and confirm the connection.

⚠️ Attention: Avoid using unknown apps to share Wi-Fi over Bluetooth—they may collect data about your networks. Proven options: Files by Google, Xender, Send Anywhere.

The transmission speed via Bluetooth is 1–2 Mbps, so the process can take up to 10 seconds. But the method works even on Android 5.0 And iOS 9.

5. Wi-Fi Sharing Apps (for Advanced Users)

If standard methods don't work, you can use specialized apps. They're handy when you need to share Wi-Fi several devices at the same time or save connection history.

Top 3 verified apps:

• 🔹 WiFi Map — stores a map of open networks and allows you to share saved passwords via a link.
• 🔹 Instabridge - automatically connects to networks shared by other users (there is a security risk!).
• 🔹 WiFi Key Share — generates QR codes and exports passwords in encrypted form.

⚠️ Attention: Apps like Instabridge may share your data with third parties. Please check permissions before using Settings → Applications → Permissions and disable access to contacts/geolocation.

How to transfer Wi-Fi via WiFi Key Share:

1. Install the application on both phones.
2. On the sending phone, select your network from the list and tap Share.
3. Generate a QR code or send data via Nearby Share (for Android).
4. On the second phone, scan the code or accept the file.

6. Manually enter the password (if nothing works)

If all automatic methods are unavailable, the only option left is manual inputTo avoid mistakes:

• 🔠 Use Notebook or Google Keep to temporarily save the password.
• 🔍 Check the case of characters - passwords WiFi123 And wifi123 are considered different.
• 📎 If your password contains spaces, make sure they are not replaced with underscores (_).

How to find out the password for the current network:

• 📱 Android: Go to Settings → Wi-Fi, tap on the network → "Share." The system will ask for a PIN or fingerprint.
• 🍎 iPhone: Go to Settings → Wi-Fi, click on i next to the network → “Copy password” (required) iOS 16+).

7. Wi-Fi Transfer via USB Cable (for Technicians)

This method is suitable for advanced users and demands ROOT rights on Android or jailbreak on iPhone. It's useful if you need to transfer Wi-Fi settings to a device without a display (for example, Raspberry Pi or Android TV).

Instructions for Android:

1. Connect the phones via USB cable (turn on USB debugging V Settings → For developers).
2. On your computer, run the command:

   adb pull /data/misc/wifi/WifiConfigStore.xml

   This will copy the Wi-Fi settings file.

3. Transfer the file to the second phone in the same folder (ROOT rights required).
4. Restart your device.

⚠️ Attention: Incorrect editing of files in /data/misc/wifi/ may lead to loss of all saved networksMake a backup before experimenting!

For iPhone the process is more complex and requires:

• Installations jailbreak (for example, through checkra1n).
• Access to the file system through Filza or iFunBox.
• Backup keys in /var/preferences/SystemConfiguration/com.apple.wifi.known-networks.plist.
