To find the WiFi password in Windows 10, you can use the built-in Network and Sharing Center. Here's how:
Open the Start menu and type "Network and Sharing Center" in the search bar. Click on the "Network and Sharing Center" result to open the settings page.
In the Network and Sharing Center, click on "Change adapter settings" on the left side of the window.
Right-click on the WiFi network you're currently connected to and select "Status" from the context menu.
In the WiFi status window, click on the "Wireless Properties" button.
In the wireless properties window, click on the "Security" tab and then check the box next to "Show characters" to reveal the WiFi password.
The WiFi password will now be displayed in the "Network security key" field. You can copy it and use it to connect other devices to the network.
Keep in mind that this method only works if you're currently connected to the WiFi network and have previously entered the password. If you haven't connected to the network before or have forgotten the password, you'll need to contact the network administrator or use the router's default password to access the network settings and change the password. I hope this helps! Let me know if you have any other questions.
