As long as you're connected to or nearby a Wi-Fi network, it's easy to find the password on iOS.
For this to work, you must be either connected to the Wi-Fi network or have connected to it in the past and be near enough to the router for the network to appear in your settings. If you meet these requirements, launch the Settings application on your iPhone or iPad running iOS 16 or iPadOS 16 and do the following:
1. Go to Wi-Fi.
2. Find the Wi-Fi network you want the password for and tap on the blue information icon to the right of the network name.
3. Tap on Password and use Face ID, Touch ID or enter your passcode to view the password.
4. Finally, hit Copy to save the password to your clipboard.
You can view passwords for any Wi-Fi networks you've ever connected to, as long as you're currently connected to it or near enough that it appears under My Networks.
You can then paste the Wi-Fi network password into a text message or email to share it with someone, or just tell them the password.
