So I know something that may or may not be helpful to other people. If you want to find your Wi-Fi password but can't figure out how to find it on your phone or computer, you can simply use Windows Powershell. I suppose this is already listed by Microsoft, but just in case I made a post about it. I also have a video showing how you would do it (listed below). If you want to find your password, open Windows Powershell (or CMD) and type in the following command;
netsh wlan show profiles
When you do this, it will list all the routers your computer has connected to, and the SSID of said interface(s). Find the name of your network and then type in this command;
netsh wlan show profile name= {put your WiFi SSID here} key=clear
Where it says key content is where you will find your password.
Now according to the timeframe in which I made the video listed below, I found my internet password using Powershell. However, it may not work anymore due to the fact that I made the video a year ago. I attempted to see if it still worked, but since I am under Family Safety restrictions, I believe that I cannot see the name of internet passwords due to my lower rank account.
Here is the video I made for how to do it;

Hope this helps you and have a nice day.
