Find Any WiFi Password on a Windows Computer

Find Any WiFi Password on a Windows computer

By Strictly-Software

The title is a little misleading as it doesn't bring you back to the early 2000's and let you go driving around estates with a laptop, breaking into password encrypted WiFi routers. Not that you used to need to as in most estates your computer could pick up an unlocked router or three without a problem.

This is slightly different in it allows you to find ANY password that belongs to a router your PC/Laptop has been connected to in the past.

You may not like writing things down and have had a memory slip or you haven't used the router for so long the password escapes any looks for it.

First - Find out what you can access

This bit allows us to find out all the WiFi routers such as friends routers and gadgets like Chromecast that you have forgotten the password to.

Open your command prompt in administrator mode otherwise this won't work.

Once you have your command prompt up lets find out what WiFi spots we have connected to in the past or have access to. If you were around a friends one time and connected but forgot the password then you may need to use this to re-gain it if his WiFi router is in the list.

Type the following into the prompt: netsh wlan show profiles

It should then list all the routers you have had connections to from the computer you are on.

C:\Windows\system32>netsh wlan show profiles 

User profiles
-------------
    All User Profile     : Chromecast1034
    All User Profile     : BTHub4-NX23
    All User Profile     : TALKTALK-3ERA24
    All User Profile     : virginmedia8817891
    All User Profile     : strictlywifi10x
    All User Profile     : strictly-ukhorse-air

Now we have a list of spots and we pick the one we need the password for. The command is pretty similar to the preceding one it just needs the routers name added to it and the term key=clear. If you don't add this to the end then you won't get to view the password in clear text.

netsh wlan show profile BTHub4-NX23 key=clear

This will give you detailed info on the router, whether it connects automatically, authentication mode e.g WPA2 and even details of your current cost and whether you are over the data limit set by your provider.

Lets try and find the password for the connection BTHub4-NX23

C:\Windows\system32>netsh wlan show profile BTHub4-NX23 key=clear
