Situations where you urgently need internet access but don't know or have lost the password for the network you need arise quite often. This could be when visiting friends, working in a coworking space, or simply wanting to save bandwidth at a cafe. However, it's important to understand that modern encryption protocols, such as WPA3, are created specifically to prevent unauthorized access by third parties.
In this article, we'll look exclusively at legal and technical methods that allow a device to connect to an access point without manually entering a long character string. We won't discuss hacking methods or the use of hacking software, as this violates the law and ethical standards. Instead, we'll focus on the built-in features of routers and operating systems designed to make life easier for users.
The basic principle underlying most of the methods described is authorization via physical contact or a trusted device. If you have access to the router itself or a device already connected to the network, the task is accomplished in a matter of minutes. Otherwise, connecting to someone else's closed network without the owner's knowledge is technically impossible without compromising security.
Using WPS technology for quick connection
One of the easiest and most common ways to connect to Wi-Fi without knowing the password is to use technology WPS (Wi-Fi Protected Setup). This feature was developed by the Wi-Fi Alliance specifically to simplify the pairing process. Instead of entering a complex security key, the device exchanges encrypted data directly with the router at the press of a button.
To implement this method, there must be a physical button on the body of your router, often labeled as WPS or indicated by the two arrows icon. On Android smartphones, this feature is often built into the system, although in recent OS versions it may be hidden in the accessibility menu. Windows computers also support WPS, but it requires proper configuration of the wireless adapter drivers.
The connection process is as follows: you select the desired network from the list of available networks, the system asks for a password, but instead of entering characters, you press the WPS button on the router. The device automatically reads the configuration and establishes a connection. This works because the router briefly opens a port for trusted devices within range.
⚠️ Attention: WPS technology has known security vulnerabilities, so many modern router manufacturers disable it by default or remove the physical button altogether. If the button doesn't press or the indicator light doesn't light, the function may be blocked in the administrator settings.
It's important to note that this method only works if you're in close proximity to the signal source. Remote WPS is not possible, which provides an additional layer of security. If the router is in another room or behind thick walls, you'll have to get closer to initiate pairing.
Scanning a QR code from another device's settings
With the development of mobile operating systems, especially Android 10 and newer, as well iOS 11+, the process of exchanging network data has been significantly simplified. Now, if you have access to a friend or colleague's smartphone that is already connected to the desired Wi-Fi, you can access the internet simply by scanning a QR code. This is the fastest and most secure method, without requiring dictation.
On Android devices, the process is as follows: the phone owner goes to Wi-Fi settings, selects an active network, and taps the "Share" button or the gear icon. A QR code containing encrypted information about the network's SSID and access key appears on the screen. All that's left to do is open the default Camera app or a code scanner and point the camera at the screen.
In the Apple ecosystem, the mechanism works through a protocol Airdrop and device proximity. If you're trying to connect from an iPhone and there's another iPhone or Mac nearby with Bluetooth enabled that's already authorized to the network, a notification will appear on the owner's screen requesting access. They can simply tap "Share Password," and the fields on your device will be automatically filled in.
- 📱 Android: Settings → Wi-Fi → Tap the gear → Share (QR code).
- 🍏 iOS: Bring the devices close → Tap "Share password" on the host device.
- 💻 Windows 10/11: There is no built-in QR code generation function, but you can use third-party utilities or your phone as an intermediary.
This method eliminates human error: you can't mistype a character or mix up the case of letters. Furthermore, the QR code is dynamically generated by the system, making it disposable and safe for transmission in public places. However, it's important to remember that scanning codes from unknown sources online is strictly prohibited, as they may lead to phishing sites.
Accessing router settings via the web interface
If you own the network or have physical access to the router's administrative panel, you can find or change the password directly. To do this, connect to the device via a LAN cable or an existing Wi-Fi connection (if the other device has one) and log in to the web management interface.
The login address is usually indicated on a sticker on the bottom of the router. Most often, this is 192.168.0.1, 192.168.1.1 or a domain name like tplinkwifi.netTo log in to the panel itself, you will need the administrator login and password, which by default are often equal to admin/admin, if they have not been changed previously.
192.168.0.1192.168.1.1
192.168.31.1
After successfully logging in, you need to find the section responsible for the wireless network. It may be called Wireless, Wi-Fi Settings or Wireless mode. In the security subsections (Security) or key settings (The current password will be displayed in the text field. You can copy it or change it to something easier to remember.

Keep in mind that the interface may differ between different manufacturers, but the logic remains the same. If the default credentials don't work, it means the password has been changed by the previous user. In this case, the only solution is a full reset, as discussed below, but this will result in the loss of all current provider configurations.

Viewing a saved password on a Windows computer
It often happens that your laptop or desktop computer is already connected to a Wi-Fi network, and you need to connect your phone or tablet to the same internet connection. In the operating system Windows The profiles of all networks to which the device has ever connected are stored, and the password can be viewed in the properties of the active connection.
To do this, open the Network and Sharing Control Panel. In Windows 10 and 11, you can do this through the Settings menu or the classic Control Panel. Find your active connection, go to its properties, and select the Security tab. There you'll find the "Network Security Key" field, which is hidden by asterisks by default.
To see characters, check the box next to "Show entered characters." The system may require administrator privileges to perform this action. After confirmation, you'll see the password in plain text and can rewrite or copy it.
An alternative, more advanced method is to use the command line. This method is useful if the graphical interface isn't working correctly or you prefer console commands. Open the command line as administrator and enter the command to display the specific network profile.
netsh wlan show profile name="Network_Name" key=clear
As a result of executing the command in the "Security Settings" section (Security settings) there will be a line "Key content" (Key Content), where the password you're looking for is displayed. This works for any saved network, even if it's not currently active. The key is to know the exact profile name (SSID).
⚠️ Attention: Viewing passwords is only possible on a device that has successfully logged into the network before. If the computer has never connected to this Wi-Fi network, the key will simply not be stored in its memory.
Using the provider's mobile application
Modern internet providers and router manufacturers are actively introducing their own mobile apps for managing home networks. Programs such as My TP-Link, Keenetic, Yandex Internet or applications from major operators (Rostelecom, MTS, Beeline) allow you to manage your network remotely.
If the router is linked to the provider's cloud account, you can log in to the app from your smartphone using the owner's account. The app interface often has a "Guests" or "Guest Access" section, which allows you to generate a temporary password or QR code to connect new devices without revealing the master key.
This method is convenient because it doesn't require you to be physically near the router. You can provide access to guests from another room or even another city, as long as the router has internet access and remote access is configured. This also allows you to create isolated guest networks, limiting guests' access to your local files.
