Windows remembers every Wi-Fi password you have used. This is how you reconnect to those networks. Also, it's the way you can view the saved password of any network you have connected to your computer whose operating system is Windows 10.
Download WirelessKeyView from NirSoft
You can see the saved passwords with command line tools built into Windows, but we recommend the free WirelessKeyView application from NirSoft.
It is a lightweight tool that you don't even have to install to use: just download it, open the ZIP file and then double-click on the included EXE file.
If you have hidden file extensions, open the "WirelessKeyView" application file. Then you will see a list of saved network names and their passwords stored in Windows.
Some antivirus programs may say that WirelessKeyView is malware. That is a false positive. If so, we have never had problems with the free utilities of NirSoft. Unlike many modern Windows programs, they don't even contain adware.
The "Network Name" column shows the name of the Wi-Fi network, in other words, your SSID. To find the password associated with a network, look in the "Password (Ascii)" column for that network name. And this is the password you type to connect to that network.
To back up this information, you can select File and then Save all items. You will get a text file that contains this information, so you can take it with you to a new computer or store it for later.
Use the command line
The Windows 10 Standard Control Panel only allows you to 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 will have to use command line tools to discover this information.
To find a password in Windows without third-party software, open a command prompt or PowerShell window. To do this, right-click on the Start button or press the Windows + X tecals. Then click on "PowerShell".
Now, run the following command to view the list of network profiles saved on your system:
netsh wlan show profiles
Find the name of the network for which you need the password and then execute the following command, replacing NETWORK with the name of your network:
netsh wlan show profile name="NETWORK" key=clear
Now, search for "Security Settings" in the output. The "Key content" field shows the Wi-Fi network password in plain text.
Repeat this process for each Wi-Fi network for which you want to find the password.
If you don't have it saved in Windows, there are many other ways you can find a forgotten Wi-Fi password. Even on another device such as a Mac, in a router's web interface or even printed on the router.
Now you can get your Wi-Fi password
Windows brings you this mode through the command prompt or PowerShell. This in order to improve your user experience with respect to the wireless networks to which you connect. For whatever reason, you can always locate your passwords.
