Windows remembers every Wi-Fi password you’ve ever used. That’s how it connects to these networks. Here’s how you can view the saved password of any network you’ve ever connected to on a Windows PC.
Download NirSoft’s WirelessKeyView
You can view saved passwords using the built-in command line tools in Windows, but we recommend NirSoft’s free WirelessKeyView app. It’s a lightweight tool that you don’t even need to install — just download it, open the ZIP file, and then double-click the included EXE file (if you have file extensions hidden, open the «WirelessKeyView» application file). You will then see a list of saved network names and their passwords stored by Windows.
Update : Some anti-virus programs may say that WirelessKeyView is malware. That’s a false positive if so — we’ve never had a problem with NirSoft’s free utilities. Unlike many modern Windows programs, they do not even contain adware.
The Network Name column displays the name of the Wi-Fi network, in other words, its SSID. To find the password associated with the network, look in the «Key (Ascii)» column for the name of the network. This is the password you enter to connect to this network.
To back up this information, you can choose File > Save All Items. You will receive a text file containing this information so you can take it with you to your new computer or save it for later use.
Use command line
The standard Windows 10 control panel only allows you to see the password of the Wi-Fi network you are currently connected to. If you don’t want to download third party software, you will have to use command line tools to find out this information.
