It's quite common to need to connect a new gadget to your home network but forget or don't know the password. Fortunately, if at least one device (such as a laptop or desktop PC) already has an active connection to the router, extracting the security key is easy. Modern operating systems store this data in encrypted form but provide tools for viewing it to users with administrator rights.
In this guide, we'll cover proven methods for obtaining network information through the Windows interface, command line, and specialized utilities. You'll learn how to safely read saved data and quickly enter it on your smartphone. It's important to understand that access to security settings requires care to avoid accidentally changing other router settings.
Methods vary depending on the operating system version and device type. We'll look at both standard tools Windows 10 and 11, as well as more advanced options for experienced users. The main thing is to follow the instructions step by step to avoid input errors.
Viewing a saved password through Windows settings
The easiest and most secure way to find the access key is to use the operating system's graphical interface. This method doesn't require installing third-party software or knowing complex commands. However, it only works if the computer is currently connected to the network or has previously connected to it.
First, you need to open the Network Control Panel. Press the key combination Win + R, in the window that appears, enter the command ncpa.cpl and press Enter. The Network Connections window will open, where you need to find the active adapter. Wi-FiIf you're using a wired connection, this method via the adapter properties may not work directly, and it's better to use the command line, which is discussed below.
Double-click the wireless network icon or right-click and select "Status." In the window that opens, click "Wireless Network Properties." Go to the "Security" tab and check the "Show characters" box. You may be prompted to confirm administrator privileges—confirm this. The desired character combination will appear in the "Network Security Key" field.
⚠️ Note: If the Security tab is grayed out or hidden, this may indicate that your account does not have sufficient permissions or that your organization's group policies are blocking access. For corporate networks, please contact your system administrator.
Once you receive the code, write it down or copy it. Be careful with the case of letters and similar symbols (for example, zero and the letter O), as password is case sensitiveEven a single character error will result in connection failure on your mobile device.
Using the command line to extract the key
For users who prefer a text-based interface or don't have access to graphical settings, the command line is ideal. This method is universal and works on all versions of Windows starting with XP. It allows you to not only view the current network password but also list all saved profiles.
Launch the Command Prompt as administrator. To do this, right-click the Start button and select "Windows PowerShell (Admin)" or "Command Prompt (Admin)." Enter the following command to view all saved profiles:
netsh wlan show profilesFind your network name in the list. Then enter the command to display details for a specific profile, adding the key parameter:
netsh wlan show profile name="NETWORK_NAME" key=clearIn the Security settings information block, find the line "Key Content". It will display cleartext passwordThis method is especially useful if the graphical interface is not working correctly or is frozen.
Transferring a password via QR code from a computer
Modern technology allows you not only to find out your password but also to instantly transfer it to your phone without manual entry. This eliminates the risk of typos. To do this, you can generate a QR code on your computer using online services or special apps, and then scan it with your smartphone's camera.
There are many free QR code generators available. You need to select the "WiFi" data type, enter the network name (SSID), and the password you learned earlier. Once the image is generated, simply point your phone's camera at the monitor screen. Android And iOS (version 11 and above) this action will automatically prompt you to connect to the network.
An alternative option for owners of Xiaomi, Samsung, and other Android-based smartphones is to use the "Share" feature in the WiFi settings on the already connected phone. The phone will generate a QR code that can be scanned by another device or even taken a screenshot and opened on a computer to be used as a second phone.
| Method | Complexity | Required rights | Speed |
|---|---|---|---|
| Windows settings | Low | Administrator | High |
| Command line | Average | Administrator | High |
| QR code | Low | No | Instantly |
| Third-party software | Average | Administrator | Average |
Third-party WiFi management software
If Windows' built-in tools seem inconvenient, you can use specialized software. Programs like WirelessKeyView from NirSoft or WiFi Password Revealer Saved keys are available (in one click). They're convenient for IT professionals who frequently work with multiple networks.
However, extreme caution should be exercised when using such software. Antivirus programs may detect them as potentially unwanted programs (PUPs) because they access confidential data. Download utilities only from the developers' official websites.
Some antivirus programs, for example Kaspersky or ESET, have built-in password managers that can also store copies of WiFi keys if the appropriate protection feature has been enabled. Check your antivirus software; the required code may already be saved there.
⚠️ Warning: Never install WiFi hacking programs from unknown websites. These programs often disguise themselves as Trojans and stealers that steal your personal data.
☑️ Verify your password before entering it
Features of working with macOS and iPhone
If your computer runs macOS, the process is also fairly simple, but there are some nuances. In older versions of the operating system (prior to macOS Ventura), the password can be found in Keychain Access. Newer versions of iOS and macOS now support password syncing via iCloud.
On iPhones with iOS 16 and later, Apple now allows users to view saved WiFi passwords directly in Settings. Go to Settings → Wi-Fi, tap the "i" icon next to the connected network, and tap the hidden "Password" field. The system will perform biometric authentication (Face ID or Touch ID) and display a code you can copy.
AirDrop is used to share passwords between Apple devices (Mac and iPhone). If both devices are signed in with the same Apple ID and have Bluetooth enabled, when you try to connect your iPhone to the network, a notification will appear on your Mac asking you to share the password. This is the most safe and fast method for the Apple ecosystem.
What to do if Face ID isn't working?
If biometrics aren't working, make sure a passcode is set on your device. Without a digital code, the system cannot verify your identity to reveal sensitive data.
Common problems and solutions
Sometimes users encounter a situation where the password appears correct, but the phone displays "Incorrect password" or "Unable to connect." Often, the problem lies not with the key itself, but with the router's security settings or frequency bands.
Make sure you're entering the password for the correct frequency. Routers often broadcast two networks: 2.4 GHz and 5 GHz. They may have the same name but different passwords if the settings were manually separated. Try entering the key for a different frequency.
It's also worth checking the encryption type. Older devices may not support modern standards. WPA3, while newer routers may use these by default. In this case, you'll need to temporarily enable compatibility mode (WPA2/WPA3 Mixed) on your router.
⚠️ Note: Router and operating system interfaces are updated regularly. The location of menu items may vary depending on the firmware version of your device. If you can't find the item you need, consult the manufacturer's official documentation.
Is it possible to find out the password if the computer is connected via cable?
Yes, you can. If your computer is connected to the router via a LAN cable, it still stores the WiFi profiles it has previously connected to. Use the command line (netsh wlan show profiles) to see a list of all networks ever used, even if the WiFi adapter is currently turned off.
Where can I find the password on Android if I'm already connected?
On Android 10 and above, go to Settings → Wi-Fi, tap the gear icon next to the active network and select "Share" or "QR code." The code image often has a text password underneath it, or it can be scanned by another phone.
What to do if you forgot your Windows administrator password?
Without administrator rights, you can't view saved passwords in Windows using standard tools. This is a security limitation. You'll need to either remember the password, use a different user account with administrator rights, or reset the router using the Reset button (which will require reconfiguring your internet connection).
Is it safe to use online QR code generators?
Using them to generate a code with your real password is risky, as you're entering sensitive data into someone else's server. It's better to use offline generators or built-in OS features. If you do use an online service, we strongly recommend changing the password on your router after use.
