Windows remembers all the Wi-Fi passwords you used. This is how he reconnects with these networks. Here's how to view the registered password of any network to which you are already connected on your Windows PC.
You can view saved passwords with the built-in command-line tools in Windows, but we recommend the free NirSoft WirelessKeyView app. It is a lightweight tool that you will not even need to install to use. download it, Open the ZIP file, then double-click on the included EXE file (if you have hidden file extensions, open the "WirelessKeyView" application file). You will then see a list of registered network names and their passwords stored in Windows.
The "Network Name" column shows the name of the Wi-Fi network. In other words, its name SSID. To find the password associated with a network, see the "Key (Ascii)" column for that network name. This is the password you type to connect to this network.
To save this information, you can select File> Save All Items. You will get a text file containing this information. You can take it with you to a new PC or store it for later.
Use the command line
The standard Windows 10 Control Panel does not allow you see the password of the Wi-Fi network to which you are currently connected. If you do not want to download third-party software, you must use command-line tools to discover this information.
To search for a Windows password without third-party software, open a command prompt window or PowerShell. To do this, right-click the Start button, or press Windows + X, and then click "PowerShell."
Run the following command to see the list of network profiles that are saved on your system:
netsh wlan show profiles
Find the name of the network for which you need the password, and then run the following command, replacing "NETWORK" with the name of this network:
netsh wlan displays the name of the profile = "NETWORK" key = clear
Look under "Security Settings" in the output. The "Key Content" field displays the password for the Wi-Fi network in plain text.
Repeat this procedure for each Wi-Fi network for which you want to find the password.
If you have not saved it on Windows, you can do it in many other ways. find a forgotten Wi-Fi password, including on another device (such as a Mac), in the web interface of a router or even printed on the router itself.
