How to View Your WiFi Password in Windows
Are you still using the WiFi password that is written on the back of the router your ISP gave you? If so, it’s probably some really long combination of letters, numbers and symbols that you can never remember.
Most people try to write the password down somewhere or simply check on the router every time they need to give it to someone else. Luckily, if you already have a computer connected to your WiFi network, you can easily view the password there.
In order to view the WiFi password on your Windows machine, you need to make sure you are already connected to the WiFi network or have previously connected to the WiFi network. If so, then go ahead and right-click on the WiFi icon in the system tray and choose Open Network and Sharing Center. Next, click on Change Adapter Settings in the left-hand menu. Find the icon for WiFi, right-click on it and choose Status.
This will bring up the WiFi Status dialog where you can see some basic information about your wireless network connection.
Click on the Wireless Properties button and then click on the Security tab. Here you will see a text field called Network security key. Go ahead and check the Show characters box and, voila!, you’ll now be able to see your WiFi security password.
