How to find your WiFi passwords in Windows

Your Windows computer will remember the WiFi passwords for every network it's been connected to (on the assumption it used a password and not something like a certificate or other authentication mechanism).

Now while you might think they've disappeared into the ether never to be seen again, it is possible.

  1. Start a Command Prompt
  2. Type in netsh wlan show profile to list all WiFi network profiles that have been connected to, it may look similar to:
C:\> netsh wlan show profile

Profiles on interface Wi-Fi:

Group policy profiles (read only)
---------------------------------
    <None>

User profiles
-------------
    All User Profile     : Network1
    All User Profile     : Network2
  1. Identify which one you want the details for. Then type netsh wlan show profile "WiFi network name" key=clear
  2. A long list of details should now appear. In the Security settings section, look for the Key Content field, which should be the password you are looking for
λ netsh wlan show profile "Network1" key=clear

Profile Network1 on interface Wi-Fi:
=======================================================================

Applied: All User Profile
