Why does a computer "know" the Wi-Fi password even when connected via cable?

When you first connect to a wireless network, Windows saves its settings - including the password - in a special storage WLAN-profilesThis data remains in the system. even after disconnecting from Wi-Fi and reboots. Therefore, if you've ever logged into this network over the air, the password can be retrieved at any time.

Key points:

• 🔹 Connecting via cable does not erase saved Wi-Fi profilesThey are stored separately from the current network connection.
• 🔹 Passwords are encrypted, but Windows allows you to view them through a graphical interface or command line.
• 🔹 If the computer never connected To connect to this Wi-Fi, the methods below will not work - you will need access to the router.

Exception: If the network was configured via WPS (button on the router) or Wi-Fi Direct, the password may not have been saved in the default profile. In such cases, you will have to use alternative methods (see the section on resetting the router).

2. Go to the section Network and Internet → Wi-Fi.
3. Click Managing known networks.
4. Find the name of the desired network in the list (SSID) and click on it.
5. Select Properties.
6. Scroll down to field Network password and press Show.

• 🔴 Your account does not have sufficient rights (administrator rights are required).

What to do if the list of known networks is empty?

This means there are no Wi-Fi profiles saved on this PC. Possible causes:

- The computer is new or after reinstalling Windows.

- All profiles were deleted manually through netsh wlan delete profile name=*.

- You use a corporate network with certificates (for example, in an office or university) where passwords are not stored locally.

Method 2: Extracting the password via the command line (universal)

If the GUI does not show the password, try to get it through CMDThis method works even in older versions. Windows 7/8 and does not depend on user rights (provided that the network profile exists).

Open Command Prompt as Administrator:

1. Click Win + X and select Terminal (Administrator) or Command Prompt (Administrator).
2. Enter the command to view all saved Wi-Fi networks:

   netsh wlan show profiles

   Remember the exact name (SSID) the required network.

3. Display network information by replacing NETWORK_NAME to its real name:

   netsh wlan show profile name="NETWORK_NAME" key=clear

4. Find the line Key content - this is the password.

Example of command output:

Security parameters
Authentication type: WPA2-Personal
Encryption type: CCMP
Key contents: 12345678

Make sure the network name is entered correctly (case sensitive)|

Command prompt run as administrator|

   @echo off
   for /f "tokens=2 delims=:" %%a in ('netsh wlan show profiles ^| find "All users"') do (
   netsh wlan show profile name="%%a" key=clear | findstr "SSID Key Contents" >> WiFi-passwords.txt
   )
   pause

What to do if your computer has never connected to this Wi-Fi network

If you are trying to retrieve the password from a network to which this PC is connected never connected over the air, the previous methods won't work. In this case, there are two options:

1. Access to the router:

Common mistakes and how to avoid them

When attempting to extract a password, users often encounter typical problems. Let's look at the most common ones:

• 🚫 The "Show" button is inactive

  Cause: The account doesn't have administrator rights or the profile is corrupted. Solution: Run the command prompt as an administrator and use method 2.

• 🚫 The password is displayed as dots or asterisks.

  Reason: In some versions Windows The password field may be masked. Solution: Copy it (click Ctrl + C after clicking in the field) and paste into notepad.

• 🚫 Team netsh doesn't work

  Reason: Service is missing WLAN AutoConfigSolution: Check its status in services.msc and start it if it is stopped.

If none of the methods worked, check:

• 🔍 The presence of an antivirus that blocks access to network settings (temporarily disable protection).
• 🔍 Integrity of system files (run sfc /scannow in the command line as admin).

Security: How to Protect Your Wi-Fi from Hacking

Once you know your network password, don't forget to check its security. Here 5 Key RecommendationsTo prevent unauthorized access:

• 🔒 Use WPA3 or WPA2-AES (avoid outdated WEP And WPA-TKIP).
• 🔒 Set a complex password (minimum 12 characters with letters, numbers, and special characters). Example: k7#pL9!vR2$q.
• 🔒 Turn it off WPS - This function is vulnerable to brute force attacks.
• 🔒 Change the default login/password of the router (for example, with admin/admin on unique data).
• 🔒 Enable MAC address filtering (manually add devices that are allowed access).

To check who is connected to your network:

1. Go to the router's web interface (see the section above).
2. Find the tab DHCP Clients, Connected Devices or Client list.
3. Compare the MAC addresses with your devices. Unknown addresses indicate network leakage.

⚠️ Attention: If you detect unknown devices on your network, immediately change your Wi-Fi password and reboot your router. This will disconnect all active connections.
