How to find out your Wi-Fi password via a wire: all the working methods

Forgot your home Wi-Fi password, but all your devices are already connected over the air? Or need to connect a new gadget, but the sticker on the router has long since worn off? This situation is familiar to many, especially when it comes to the complex character combinations that providers come up with. Luckily, if you have physical access to the router and a computer with a wired connection, you can recover the password. Wi-Fi It can be done legally - without hacking or compromising network security.

In this article we will look at 5 working methodsHow to find out a Wi-Fi password via a cable—from viewing saved networks in Windows to connecting to the router's web interface. All methods have been tested on current OS versions (2026–2026) and are compatible with most router models (TP-Link, ASUS, Keenetic, MikroTik etc.). Important: all actions are performed only on my network — attempting to hack other people's access points is punishable by law (Article 272 of the Criminal Code of the Russian Federation).

Before you begin, make sure that:

  • 🔌 Your computer is connected to the router via Ethernet cable (not via Wi-Fi!).
  • 🖥️ You have administrator rights on your PC (for Windows/macOS methods).
  • 📡 The router is turned on and operating normally (the indicators are green/blue).

1. Viewing a saved password in Windows

If your computer has ever connected to this Wi-Fi network (even over the air), the password may have been saved in the system. In Windows, you can retrieve it without any additional software using Control Panel or Command line.

The method works on Windows 10/11 and doesn't require superuser rights (a standard account with administrator rights is sufficient). Follow the instructions:

  1. Open Control Panel (click Win + R, enter control and press Enter).
  2. Go to the section Network and Internet → Network and Sharing Center.
  3. Click on the name of your Wi-Fi network (next to the inscription Connections).
  4. In the window that opens, click Wireless network properties, then go to the tab Security.
  5. Check the box Show entered characters — the password will be displayed in the field Network security key.

Your PC has connected to this Wi-Fi network before|You have administrator rights|The network is visible in the Network and Sharing Center|The password was not reset after connecting-->

If the method doesn't work, try the alternative method via Command line:

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

Replace NETWORK_NAME with the name of your Wi-Fi network (case-sensitive!). In the command results, find the line Key content - this is the password.

⚠️ Attention: If the network is configured via WPA3-Enterprise or 802.1X, the password will not be displayed in this form - access to the authentication server (usually used in corporate networks) will be required.

2. Extracting the password via macOS (Keychain Access)

On computers MacBook or iMac All saved passwords, including Wi-Fi, are stored in the system storage Keychain Access (Keychain). To view them:

  1. Open Spotlight (click Cmd + Space) and enter Keychain Access.
  2. In the left menu, select System (or Local elements, if the password is saved under your account).
  3. In the search bar, enter the name of your Wi-Fi network.
  4. Double-click on the found entry and check the box. Show password.
  5. Enter your account password macOS - after this the network security key will be displayed.

If the entry is not found, try searching in the section Passwords or check if this Mac has connected to the network before. macOS Ventura and a newer interface Keychain Access slightly changed, but the logic remained the same.

3. Connecting to the router's web interface

The most universal way is to access the router settings through a browser. All you need is a cable and a standard IP address devices (usually 192.168.0.1 or 192.168.1.1). Algorithm of actions:

  1. Connect your computer to the router via LAN port (any free slot, except WAN/Internet).
  2. Open your browser and enter your router's IP address in the address bar. Standard addresses:
    • 🌐 192.168.0.1 — TP-Link, D-Link, Tenda
    • 🌐 192.168.1.1 — ASUS, Keenetic, Zyxel
    • 🌐 192.168.8.1 — Mercusys, some models TP-Link
  • Enter your username and password to log in. By default, this is often admin/admin or admin/empty. For exact information, see the router's sticker.
  • Go to the Wi-Fi settings section (usually Wireless, Wi-Fi or Wireless network).
  • Find the field Password, Key or Security key — this will be your password.

    • If you changed your router's default password and don't remember it, you'll need to reset it to factory settings. To do this:

    1. Click the button Reset on the back panel of the router (hold for 10-15 seconds).
    2. Wait for the reboot (the indicators will blink and light up steadily).
    3. Log in to the web interface using the default IP address and default login/password.
      4. ⚠️ Warning: Resetting your router will delete all settings, including the network name, password, provider binding, and firewall rules. After the reset, you'll need to reconfigure your internet connection (the details for this are usually included in your contract with your provider).
      How can I find out my router's IP address if the default ones aren't working?

      If 192.168.0.1 And 192.168.1.1 do not open, determine the IP via the command line:

      • On Windows: Run ipconfig and find the line Main gateway.
      • On macOS/Linux: run netstat -rn and look at the address in the line default.

    This will be the IP of your router.

    4. Using Linux (terminal and utilities)

    In distributions Linux (Ubuntu, Debian, Fedora, etc.) Wi-Fi network passwords are stored in configuration files NetworkManager or wpa_supplicantTo extract them:

    Method 1: Through nmcli (for NetworkManager):

    nmcli -s -g 802-11-wireless-security.psk connection show "NETWORK_NAME"

    Method 2: Via configuration file (for wpa_supplicant):

    sudo cat /etc/NetworkManager/system-connections/"NETWORK_NAME".nmconnection | grep psk=

    If you use KDE Plasma, you can use the graphical interface:

    1. Open Network settings (or KDE Wallet).
    2. Find your network in the list of saved connections.
    3. Click Change → Security → Show password.

    In some distributions (for example, Arch Linux) you may need to install additional packages:

    sudo pacman -S networkmanager

    5. Alternative methods: mobile devices and specialized software

    If you don't have a computer at hand, but you have a smartphone Android With root rights, the password can be extracted through applications like WiFi Password Viewer or Root BrowserInstructions:

    1. Install one of the applications from Google Play.
    2. Grant root access (if requested).
    3. Find your network in the list and copy the password.

    For iPhone Without jailbreaking, this method won't work—Apple strictly restricts access to system files. However, if the iPhone has previously connected to the network, the password can be viewed on Mac, synchronized with the same iCloud-account (via Keychain Access, as described above).

    Specialized software for Windows (for example, WirelessKeyView from NirSoft) may also help, but requires caution:

    • 🔍 The program shows all saved passwords from Wi-Fi networks.
    • 🛡️ Download only from official website (avoid cracked versions).
    • 🚫 Antivirus programs may block the utility—add it to the exceptions.
    ⚠️ Warning: Using third-party software to extract passwords on someone else's computer may be considered an attempt at unauthorized access (Article 272 of the Russian Criminal Code). Use such methods only on your own devices.

    Comparison of methods: which one to choose?

    Depending on your OS, access rights, and router model, the effectiveness of these methods will vary. Below is a comparison table:

    Method OS Required rights Complexity Applicability
    Viewing in Windows Windows 10/11 Administrator ⭐ If the PC has been connected to the network before
    Keychain Access macOS Account password ⭐ If the Mac was connected to the network
    Router web interface Any Access to the router ⭐⭐ Universal method
    Linux terminal Linux Root or sudo ⭐⭐⭐ For experienced users
    Third-party software Windows/Android Administrator/Root ⭐⭐ If other methods don't work

    Critically important: If none of the methods worked, and you still have access to the router, the only option left is to reset the settings to factory defaults (using the button Reset). After this, the password will be reset to the default (indicated on the router sticker), but you will need to reconfigure the Internet.

    Common mistakes and how to avoid them

    When trying to find a Wi-Fi password via a cable, users often encounter typical problems. Here are the most common ones and their solutions:

    • 🔌 No cable connection: Check that the cable is firmly inserted into the LAN port router and PC network card. Try a different cable or port.
    • 🌐 The router's web interface won't open.:
      • Make sure you are entering the correct IP (check via ipconfig).
      • Disable your VPN or proxy as they may be blocking access.
      • Try a different browser (for example, Firefox instead of Chrome).
    • 🔑 The router password doesn't work.:
      • If you changed it, the only option left is to reset the settings.
      • On some routers (Keenetic) The default password is generated automatically - look for it on the sticker.
    • 📵 The network is not showing up in the saved list.:
      • In Windows, check the partition Managing known networks.
      • On macOS, make sure the network is not removed from Keychain Access.

    If the router gives an error 404 Not Found when trying to access the web interface, it may be disabled HTTP server in the settings. In this case, only a reset or connection via Telnet/SSH (for experienced users).

    FAQ: Answers to frequently asked questions

    Is it possible to find out a Wi-Fi password without accessing the router?
