Needing to access a wireless network but not knowing the password is a common occurrence. This could be a friend's guest network, a forgotten key to your own home hotspot, or the need to connect a new device to a router whose data has been lost. Modern network infrastructure Wi-Fi It provides various encryption protocols designed to protect traffic from outsiders, but legitimate ways to restore access still exist.
It's important to note that hacking into someone else's network without their permission is illegal. This article only covers methods applicable to your own devices, routers to which you have physical access, or networks to which access was previously saved on one of your devices. Understanding the operating principles authorization will help you not only restore the connection, but also protect your own network from unauthorized access.
The process of connecting or recovering an access key varies depending on the device's operating system, router model, and security settings. Below, we'll detail the steps for various platforms and usage scenarios, including working with the command line and the device's web interface.
Using a previously connected device
The easiest and most common way to find the required code is to use a device that has already successfully connected to the access point. Modern smartphone and computer operating systems store network parameters, including encryption keys, in secure memory for automatic reconnection. If you have a laptop or phone handy that has previously successfully connected to the desired access point, router, the task becomes much simpler.
On devices with the operating system Windows The procedure for viewing a saved password is built into the standard network settings interface. You need to open the Network Control Panel, find the properties of your active wireless connection, and go to the Security tab. There, unchecking the "Hide characters" option will display the saved key in plain text. Similar functionality is also available in macOS, where the data is stored in the keychain.
Mobile operating systems also allow access sharing. Android (starting with version 10) and iOS (Starting with version 13), a QR code generation feature has been implemented for guest connections. By scanning this code with another device's camera, you'll instantly gain access without having to manually enter characters. This is especially convenient, as it eliminates the risk of errors when entering complex combinations.
It's worth keeping in mind that on some corporate devices, administrators may block the ability to view saved passwords for security reasons. In this case, standard methods for displaying characters may be unavailable, requiring alternative methods, such as accessing the router's settings.
Accessing router settings via the web interface
If none of your devices remember the password, but you have physical access to the router, the most secure way is to log into its control panel. Almost all modern router models, whether TP-Link, Asus, Keenetic or MikroTik, have a built-in web server. To log in, you need to connect your computer to the router using LAN cable or via Wi-Fi (if you don’t need internet access yet, but the local network is working).
The login address is usually found on a sticker on the bottom of the device. This is most often the IP address. 192.168.0.1 or 192.168.1.1, or a domain name like tplinklogin.netBy entering this address in your browser, you will see an authorization form. The factory login and password are also indicated on the sticker (often this admin/admin). If you previously changed this data and forgot it, you will have to perform a factory reset.
After successful authorization, you need to find the section responsible for wireless networks. Depending on the firmware, it may be called Wireless, Wi-Fi, Wireless mode or WLAN. Inside this section, look for the “Security” subsection (Security) or "Wireless Network Settings." This is where the current password is displayed, which you can copy or change to a new one.
⚠️ Attention: If you change the password in your router settings, all previously connected devices will lose their connection. You'll have to reconnect each device using the new access key.
It's important to note that interfaces may differ from manufacturer to manufacturer, but the logic remains the same. For example, in routers Keenetic The settings are located in the “My Networks and Wi-Fi” menu, and in Asus — in the left column of the "Wireless Network" menu. Be careful not to confuse the settings for the guest network and the main network.
Connecting using WPS
Technology WPS Wi-Fi Protected Setup (WPS) was developed to simplify connecting devices to a network without having to enter a lengthy password. If your router has a physical WPS button and the device you're connecting to (such as a printer, TV, or older smartphone) supports this feature, the process takes just seconds. This is one of the fastest methods when the password is unknown or too complex to enter manually.
To establish a connection, press the WPS button on the router. This may be a separate button or combined with the Wi-Fi power button (in which case, press it briefly rather than holding it down). Once activated, the WPS indicator on the router will begin flashing, indicating searching mode. Within the next two minutes, start searching for networks on the client device and select the WPS connection option.
However, it's important to keep security in mind. The WPS protocol has known vulnerabilities that allow attackers to brute-force the PIN code. Therefore, many modern routers disable this feature by default or only allow the push-button method (PBC), which is more secure than entering a PIN code. If security is your top priority, it's best to disable WPS in the settings after connecting all devices.
Using the Command Prompt in Windows
For advanced users who prefer to work with the console, the operating system Windows provides powerful network management tools via the command line. This method not only allows you to view saved networks but also export their profiles, including passwords, in text format. This is especially useful if the graphical interface isn't working correctly or information is needed for a script.
First, you need to run the command prompt as administrator. Enter cmd In the search box, right-click and select the appropriate option. The first step is to display a list of all saved Wi-Fi profiles. To do this, use the command:
netsh wlan show profilesIn the list that appears, find the desired network name (SSID). Then run the command to display the details of a specific profile, adding the key key=clear, which instructs the system to show the key in clear text:
netsh wlan show profile name="Network_Name" key=clearIn the command results, find the "Key Content" line. This is where the password you're looking for will be located. Note that the network name in the command must be enclosed in quotation marks if it contains spaces. This method works on all current versions of Windows, starting with Windows 7.
What should I do if the command returns an access denied error?
The "Failed to execute command" error often occurs if you haven't run the console as an administrator. Also, make sure you entered the network name correctly, including capitalization.
Connection Features on Android and iOS
Mobile platforms have their own unique way of handling wireless connections. Unlike desktop systems, mobile OSes are more strict about security and don't allow applications to simply read saved passwords from other networks without permission. root rights (on Android) or jailbreak (on iOS). However, it's entirely possible to access or share it using standard tools.
On devices Android With version 10 and above, the password for the current or previously connected network can be viewed as a QR code. Go to Wi-Fi settings, select the desired network, and tap "Share" or the gear icon. The system will ask you to confirm your identity (fingerprint, face, or PIN), after which it will display the QR code. The password itself is often written in small print underneath it. If there is no text, the code can be scanned with any QR reader, and the scan results will show a string like this: WIFI:S:MyNetwork;T:WPA;P:MyPassword;;, Where P - this is the password.
In the ecosystem Apple (iOS) uses the iCloud "keychain" principle. If you own an iPhone and a Mac, the password entered on one device is automatically available to your other devices linked to the same Apple ID. To connect a new device (for example, a friend's iPad), simply bring your unlocked iPhone close to the iPad. A pop-up window will appear on the iPhone screen asking if you want to share the password. Tap "Share" to automatically transfer the encryption key.
- 📱 On Android, use the "Share Wi-Fi" feature to generate a QR code.
- 🍏 On iOS, use Password Sharing via Bluetooth and iCloud.
- 🔒 Without root access, you can't view passwords for other networks in the system's text file.
It's important to understand that these methods only work if your device is already "familiar" with the network or is located near a trusted device. Simply "stealing" a password out of thin air through a standard mobile phone interface is impossible for security reasons.
Resetting the router to factory settings
If none of the above methods helped, and access to the router control panel is also lost (the administrator password has been changed and forgotten), there remains the last radical method - a complete reset of the settings (Reset). This step will return the device to its out-of-the-box state, restoring the factory username, Wi-Fi password, and login address found on the sticker.
To perform a reset, find the hole marked on the router body Reset or RestoreIt's usually recessed into the housing to prevent accidental pressing. You'll need a thin object, such as a paperclip or toothpick. With the router powered on, press the button inside the hole and hold it for 10-15 seconds. The lights on the front panel should blink or go out, indicating the reboot process has begun.
After rebooting, the router will create an open network with the factory name (SSID). Once connected, you can access the settings using the address on the sticker and the default credentials. However, remember: this step will erase all your personal settings, including your ISP connection type (PPPoE, L2TP, etc.), which you will need to re-enter. If you don't know your ISP's internet connection details, you shouldn't reset the router.
⚠️ Attention: Before resetting, make sure you have a valid internet service provider contract or saved login credentials (username and password). Without these credentials, the router will not be able to access the internet after the reset.

Frequently Asked Questions (FAQ)
Is it possible to connect to a neighbor's Wi-Fi if you only know the network name?
Without knowing the password, it's impossible to connect to a secure network (WPA2/WPA3). Encryption protocols reliably protect data transmission. The only legal way is to obtain the password from the owner or use the WPS function if it's enabled and you have physical access to the button on the router.
What should I do if the password sticker on my router has worn off?
If the sticker has worn off and you haven't changed your password, try the standard combinations: admin, 1234, 12345678 or passwordYou can also try searching for your router model online and finding the default password for that model. If the password was previously changed, only a full reset will help.
Is it safe to use Wi-Fi hacking software?
Most of these open-source programs contain viruses or are fraudulent. Real security audit tools (like Aircrack-ng) require advanced technical knowledge and are used by cybersecurity specialists. For the average user, the risk of infecting their device with malware is much higher than the chance of obtaining a working password.
Why does the phone say "Saved" but won't connect?
This means the device has remembered the network, but is being rejected when attempting to connect. This could be due to a changed router password, MAC address filtering (blacklisting) being enabled, or the router not assigning IP addresses. Try "Forget Network" on your phone and re-entering the password.
Can antivirus software block Wi-Fi connections?
Yes, some antivirus protection features (such as Home Network Protection or Firewall) may block connections to new or public networks, deeming them suspicious. Try temporarily disabling your antivirus to check.
