Everyone is familiar with the situation where one device has internet access and another does not. Often, there's a need to urgently share a password with guests or connect a tablet or keyboard for data entry. Fortunately, modern smartphones allow you to do this with just a few taps on the screen, eliminating the need to type complex character combinations.
There are several proven ways to solve this problem, from scanning a QR code to creating a full-fledged access point. The choice of method depends on the operating system, version Android or iOS, as well as the distance of the receiving device. In this article, we'll examine all the current connection transfer options.
The fastest and most secure method is to use the QR code built into the system. However, if the recipient's device is too old or the camera isn't working, password sharing features in the Apple ecosystem or manually creating a hotspot can help. Understanding how it works NFC and security protocols will help avoid mistakes.
Using a QR code for quick transfer
The most elegant solution for transmitting network credentials is to generate a QR code on a device that is already connected to Wi-Fi. In the operating system AndroidStarting with version 10, this feature is built in natively. You don't need to install third-party apps or navigate complex menus.
To use this method, open your wireless network settings. Find the name of your current network and tap the gear icon or the "Share" button. The system will ask you to verify your identity with a PIN or fingerprint, after which a pattern will appear on the screen.
- 📱 Unlock the phone from which you want to share access.
- 🔗 Go to
Settings → Wi-Fiand select the active network. - 👁️ Click the Share button or the QR code icon.
- 📸 Point the camera of the second phone at the square that appears.
⚠️ Attention: The QR code contains the password in clear text. Don't take screenshots or send the code image to strangers via messaging apps, as anyone who scans the code will gain access to your network.
Devices based on iOS also support this feature, but with an important caveat: both phones must be in each other's contacts, and Bluetooth must be enabled on both devices. When attempting to connect to the network on the second iPhone, a notification will pop up on the first one, asking if it wants to share the password.
Setting up an access point (Hotspot)
If direct password exchange isn't possible, tethering remains the most versatile solution. Your phone turns into a router, creating a new network that other devices can connect to. This consumes data if you're not connected to Wi-Fi, or simply rebroadcasts the signal.
To activate the mode, you need to go to the appropriate settings section. Android It is often called "Access Point and Tethering" and in iPhone — "Modem Mode." It's important to set a strong password here to prevent random passersby from connecting to your network.
Creating a hotspot isn't just a matter of flipping a switch. It's important to understand the difference between frequencies. Modern smartphones allow you to choose between the 2.4 GHz and 5 GHz bands. The former provides better coverage, while the latter offers faster speeds but a shorter range.
☑️ Setting up a secure hotspot
After setting up on the second phone, you need to open the list of available networks, find the name of your device (usually this is the phone model, for example, Samsung Galaxy S23) and enter the set password. The connection is established automatically.
Transferring Internet via Bluetooth
Although this method is considered obsolete due to its low data transfer speed, it remains the only viable option in some situations. For example, when the Wi-Fi module on the receiving device is faulty, but Bluetooth works. The speed won't be suitable for watching video, but it's suitable for sending text messages or light web pages.
The pairing process requires careful attention. Both devices must be visible to others. After pairing, you must enable "Internet access" or "Bluetooth tethering" in the Bluetooth settings.
⚠️ Attention: Connection speeds via Bluetooth rarely exceed 2-3 Mbps. Don't attempt to use this method for downloading large files or making video calls.It is important to note that on iPhone This method works almost seamlessly with a Mac or iPad, while between Android and other systems may require additional pairing confirmation codes.
Specifics of transferring between Android and iPhone
Cross-platform compatibility often raises questions. If you have an iPhone and your friend comes over with an Android smartphone, the standard "Share Password" feature (AirDrop style) won't work, as it's a proprietary Apple technology.
In this case, the owner iPhone You will have to either dictate the password manually, use a QR code if your iOS version allows you to generate one (via Shortcuts or third-party widgets), or temporarily create a hotspot. Owners Android In this situation, they have an advantage due to the versatility of QR codes.
For devices on Android The problem is solved more easily. Regardless of the brand (Xiaomi, Pixel, Honor), the code generation mechanism is the same. All you need is an iPhone with a camera that supports QR code recognition (built into iOS 11 and later).
What to do if the camera does not see the code?
If the iPhone's standard camera can't read the code from your Android screen, try taking a screenshot of the code on your Android, sending it to yourself via Messenger, and opening it on your iPhone. Then use Live Text or a third-party scanner app to recognize the text/code from the image.
Using NFC for instant connection
Near Field Communication Technology (NFC) allows you to transfer data by touching devices. On Android, there's a feature called "Android Beam" (in older versions) or "Quick Share" (in newer versions), which can transfer network settings.
However, a more common scenario is using NFC tags. You can store your Wi-Fi network profile on a special tag. When a guest holds their phone near the tag on your desk, the device will prompt them to connect to the network without entering a password.
This method is ideal for offices or coffee shops where guests frequently need access. It eliminates the human factor when entering passwords and looks professional.

When you grant access to your network, you effectively open the door to your local network. Devices connected to the same Wi-Fi network often see each other. This can be exploited by attackers for man-in-the-middle attacks.
Use the "Guest Network" feature on your router if you frequently host guests. However, if you're sharing from a phone, this isn't an option. In this case, after your guests leave, it's recommended to change your Wi-Fi password or forget the network on your device and reconnect, which will clear the connection cache.
⚠️ Attention: Never connect unknown devices to a network containing your smart cameras, printers, or NAS storage devices containing personal data. AP Isolation on your router helps, but not on a mobile hotspot.It's also worth remembering that creating a hotspot on your phone makes it visible to everyone. Use complex passwords that contain mixed-case letters and numbers to prevent brute-force attacks.
Frequently Asked Questions (FAQ)
Is it possible to share Wi-Fi if the phone is not connected to the mobile Internet?
Yes, if your smartphone is connected to a Wi-Fi network, it can broadcast that signal further via an access point (Wi-Fi Repeater feature), but not all phone models have this feature. Most often, the phone will simply transmit the password, and the second device will connect directly to the same router.
Why can't my iPhone see the Wi-Fi QR code?
Make sure QR code recognition is enabled in your camera settings. The code should also be clear and free of glare. If the code is generated incorrectly (not in a standard Wi-Fi format), the camera may ignore it.
Does sharing Wi-Fi from a phone consume data?
If you share the same internet connection you receive via a mobile network (3G/4G/5G), your data plan charges your data plan. If you rebroadcast a Wi-Fi signal (connect to Wi-Fi and share it), your mobile data plan charges no data, but your battery drains faster.
How do I hide my hotspot name?
In the access point settings (
Settings → Connections → Mobile hotspot → Setup) you can find the "Hide device" option. In this case, you will have to connect by manually entering the network name (SSID).
