Disable Viewing Wi-Fi Password in iOS16

No, you can’t disable viewing the Wifi password, you could change the device password and remove their FaceID/TouchID so they can’t login to view it. Another option would be to use a MDM but that would be too complicated.

“Unknowingly share”?

You’re really headed toward an enterprise network here, in terms of the Wi-Fi access control problems you are working to avoid or to prevent. And in terms of the added complexity.

You’re already a little behind here too, as it’s long been possible to AirDrop the Wi-Fi password.

I’d try an MDM profile for this current case, using the Apple Configurator 2 app. AC2 is free, and fairly easy to use, and avoids needing to know details of the MDM setup. I don’t have an iOS 16 test device handy to try, or I’d check whether this works myself. Creating and loading a Wi-Fi profile using AC2 is something you could experiment with.

The “nasty way” to maintain (some) control is to record the MAC addresses for the clients, and block unknown addresses. This requires you to manage each new Wi-Fi connection.

Yet more setup is RADIUS, but you’ll need a server for that. Synology NAS RADIUS, or otherwise.

As an alternative, I’d consider printing out a QR code for a guest network, and have the friends and guests scan that and join that Wi-Fi network.

You are correct on both counts. The only answer to your original question is that there is not a way, at present, to hide the Wi-Fi passwords. Furthermore, You can suggest this feature directly to Apple by leaving a product feedback here 👉Product Feedback - Apple
