It's common to need to connect a new device to a wireless network but lose or forget the password. This can happen after reinstalling the operating system on a PC or when purchasing a new device that requires credentials. Fortunately, if at least one computer is already connected to the network or has connected previously, access can be restored using the system's built-in tools, without the need for third-party software.
Modern operating systems such as Windows 10 And Windows 11, store data about previously used connections in a secure registry. This is done for user convenience, so they don't have to enter a long security key every time they automatically connect. We'll look at legal methods for extracting this information that don't violate the law and don't require hacking.
It is important to understand that the methods described below will only work if your computer has previously successfully connected to the access point in question. The system cannot display the password for a network to which the device has never connected., as this data simply wasn't saved to local storage. For such cases, there are other technical solutions that require physical access to the router.
⚠️ Warning: Using specialized software to crack passwords for other people's Wi-Fi networks without the owner's permission is illegal. All instructions described here are intended solely for restoring access to your own networks or networks whose administrator has granted you the necessary privileges.
Viewing a saved password in the Windows interface
The easiest and most accessible way to find your security key is to use the operating system's graphical interface. This method is suitable for most users and doesn't require knowledge of complex commands. The steps may vary slightly depending on the Windows version, but the logic remains the same.
First, you need to open the Network and Sharing Center. You can do this from the taskbar by right-clicking the Wi-Fi icon, or from the Control Panel. Next, go to the properties of the currently active wireless connection.
- 📡 Right-click on the network icon in the tray and select "Network and Internet settings".
- ⚙️ Go to "Advanced network settings" or "Network and Sharing Center."
- 🔗 Click on the name of your wireless network (blue text with a link).
- 🔑 In the window that opens, select “Wireless Network Properties,” then the “Security” tab.
In the window that opens, you'll see the "Network Security Key" field, where the characters are hidden behind dots or asterisks. To see them, check the "Show entered characters" box. Then password will become visible in text form and you will be able to copy or write it down.
Using the command line to extract data
For more experienced users or in situations where the graphical interface isn't working correctly, the command line is ideal. This tool allows you to interact directly with Windows system services, particularly the WLAN AutoConfig, which manages wireless connections.
Before you begin, you must launch the command prompt with administrator privileges. This is mandatory, as accessing saved security profiles requires elevated privileges. You can do this by finding "cmd" or "Command Prompt" in the Start menu, right-clicking, and selecting the appropriate option.
First, you need to get a list of all saved network profiles on this computer. To do this, enter the command:
netsh wlan show profilesFind the name of the desired network in the list. Next, use the command to display the details of a specific profile with a key. The syntax is as follows:
netsh wlan show profile name="Network_Name" key=clearIn the command output, under "Security settings," find the line "Key Content." This is where the password you're looking for will be displayed in cleartext. This method is universal and works even on Windows versions without a graphical interface, such as: Windows Server.
☑️ Check before entering commands
Obtaining a password through the router's web interface
If your computer is connected to the router via cable or Wi-Fi (even without knowing the password, if the connection is already established), you can access the router's settings. The device's web interface contains all configuration settings, including wireless network encryption keys.
To log in, you need to know the IP address of the default gateway. Most often, this is 192.168.0.1 or 192.168.1.1, but the address can be changed by the user. You can find it through the command line by entering ipconfig and find the line “Default Gateway”.
After entering the address in the browser, you will be required to log in. If you haven't changed the factory settings, they are listed on the sticker on the bottom of the router. Default logins are often admin/admin or admin/passwordAfter logging in, you need to find the section related to wireless mode.
| Router brand | Menu path (approximate) | Password field name |
|---|---|---|
| TP-Link | Wireless -> Wireless Security | Wireless Password / PSK Password |
| ASUS | Administration -> System -> Wireless Network | Authentication Method / Password |
| Keenetic | My Networks and Wi-Fi -> Home Network | Wi-Fi network password |
| D-Link | Wi-Fi -> Security Settings | PSK encryption key |
The corresponding section will contain a field containing the access key. In some firmware versions, you can simply read it; in others, you'll need to uncheck the "Hide Characters" box. If you decide to set a new password, be sure to save the changes by clicking "Save" or "Apply," otherwise the router will reboot without applying the settings.
⚠️ Note: Router interfaces are constantly updated by manufacturers. Menu locations and item names may differ from those shown in the table. If you can't find the section you need, refer to the official documentation for your model or look for screenshots of the interface for your specific firmware version.
Resetting your router as a last resort
If none of the software methods help, and access to the web interface is impossible due to a forgotten administrator password, the only drastic solution is a full factory reset (hard reset). This will return the router to its out-of-the-box state.
Most routers have a recessed button on the body. Reset or RestoreTo activate the reset, turn on the router, press this button with a thin object (paperclip, toothpick), and hold for about 10-15 seconds until the indicators flash simultaneously.
After rebooting, the device will use the default settings indicated on the factory sticker. You will be able to connect to Wi-Fi using the password on the sticker and log in to the web interface using the default login and password. However, It's important to rememberthat all your personal settings (PPPoE connection type, static IP, network names) will be deleted and will have to be configured again.
What should I do if the sticker with the factory password has worn off?
If the sticker is illegible and the reset has been performed, you won't be able to connect to Wi-Fi. In this case, the only solution is to connect your computer to the router via a LAN cable. A cable connection often doesn't require authentication (or uses the default admin/admin password), allowing you to reconfigure the wireless network and set a new password.
Using third-party software and utilities
There are many programs that automate the process of viewing saved networks. Utilities such as WirelessKeyView from NirSoft or WiFi Password Decoder, scan the Windows registry and display a list of all ever-saved profiles with passwords in a convenient format.
The advantage of such programs is the ability to quickly export a list of all passwords to a text file or HTML report. This is useful for system administrators managing multiple access points. However, using third-party software carries risks: some antivirus programs may detect such programs as hacker tools (RiskWare).
- 💻 Download utilities only from the developers' official websites.
- 🛡️ Check files with an antivirus before launching.
- 🚫 Do not use such programs on other people's computers without the owner's consent.
For one-time use on a home PC, built-in Windows tools are sufficient. Third-party software is only justified in specific scenarios, such as restoring access to a computer with a damaged graphical interface or when bulk data export is required.
Security measures and protection of your network
Knowing how easy it is to find out your Wi-Fi password if you have physical access to your computer or router, it's worth considering protecting your own network. Simple passwords like "12345678" or your birthday can be cracked in seconds, while administrator access to your PC gives you complete control over the network.
It is recommended to use a complex encryption key consisting of mixed-case letters, numbers, and special characters. The password length must be at least 12 characters. It is also recommended to disable this feature. WPS in the router settings, as it often contains vulnerabilities that allow bypassing protection.
Update your router firmware regularly. Manufacturers patch security holes that allow attackers to remotely access network settings. Don't use default passwords to access the administrator web interface—change them immediately after setting up the equipment for the first time.
Is it possible to find out a Wi-Fi password if the computer has never connected to this network?
No, this can't be done using computer software. Computers don't store information about networks they haven't connected to. The only option is to access the router settings via a cable or know the password for the device's admin panel.
Why does the command line say "Request not supported"?
This error often occurs if the command prompt is not run as administrator. The issue could also be with the Wi-Fi adapter drivers or if the network profile was previously removed from the system.
Is it safe to save a password in Windows?
Yes, Windows encrypts saved passwords and stores them in a secure area of the registry. However, if an attacker with administrative privileges gains access to your computer, they can extract this data. Therefore, it's important to protect your Windows account with a strong password.
What should I do if I forgot my router admin password?
If the default password (admin/admin) doesn't work, and you've changed it and forgotten it, the only solution is to reset the router using the Reset button. This will restore the factory settings and default login credentials.
