I reset my phone but I forgot my network password

I had to reset my iPhone, now I need to sign-in to the network, but I have forgotten my wi-fi password. How do I find it?

I did this:

Mac

Share the password from Mac

Or copy the password, if the Mac is using macOS Ventura or later:

1. Choose Apple menu  > System Settings.
2. Click Network in the sidebar, then click Wi-Fi on the right.
3. Scroll down and click Advanced to open the list of known networks.
4. Click the More button next to the network name, then choose Copy Password.
5. Paste the password somewhere else to see it. If both devices are yours, you might be able to use Universal Clipboard to paste the password directly onto your other device.

I tried to paste the password in a Pages document but what appears is what was previously copied, not the password.
