How do I find my old password or get a new Wi-Fi password for my Wi-Fi network at my home?

If the router was provided by your internet service provider, they usually have a label on the side or the back of the router with the wi-fi name and password. If you have never changed it, it should be that one.

If you did change it at any point, then you will need to consult your router's user guide for how to access its admin panel and change the wi-fi password for it. You don't get a new password, you set the password yourself, and are responsible for keeping it somewhere you can refer to it always.

If you have a Mac that is currently connected to the Wi-Fi network, you can use the Keychain Access app to find the Wi-Fi password.

You can find the Keychain Access App in the Applications folder in Finder, or using spotlight search from the menu.

Once opened, you can use the search box at the top, and enter the name of your Wi-Fi network there. It should show up as an Airport Network Password in the "Kind" column.

Double click on it to open it, then click on the Show Password checkbox at the bottom and enter your Mac's admin password. Usually it's your own user's login password. It should then show you the password.

Alternatively, if the Mac and iPhone are using the same password, the Mac should be able to automatically share the password with the iPhone. click here ➜ Share a Wi-Fi password on Mac - Apple Support

I meant the same Apple ID there.

One option to find your local Wi-Fi network password would be to use the Keychain Access app on your Mac. Run the app, and then, select "Passwords" category on the left side. Then select the "Kind" column header to sort it. Look for the Kind of "network password" to see if your local Wi-Fi network is listed. If it is select it.

Once selected, then double-click on the selection to which will open a new window to look at that entries attributes. Click on the "Show password" option. If a password exists, you will get a new window asking you to enter your Mac's Administrator password so that you can see the actual network password.

If that fails, your next option would be to review the owner's manual for your wireless router (as sberman has suggested) to see how you can gain access to what that password is ... or, most likely, how to reset it.

The answer and method depend completely on your Wi-Fi router. Consult its manual.
