iCloud I think it is the main advantage that distinguishes Apple by other device and software manufacturers. Owners of iPhone, iPad, Mac, Macbook, Apple Watch they can keep all their devices syncronized with each other through the account iCloud. Apple ID. In this tutorial you will learn how to see the passwords of the Wi-Fi networks to which you have been connected (or are connected).
In addition to documents, pictures and videos, messages, mail, notes, files and much more, in iCloud the passwords of the Wi-Fi networks to which we connected with a device are also saved. So if we go to a hotel and connect from iPhone to a wireless network with password, both iPad and M/imacBook will automatically connect to that network without having to enter the password. The network password has been saved in iCloud with the first connection a iPhone. The condition is that we have the same account on all devices Apple ID and have the synchronization active iCloud.

Double click on the name of the network for which we want to see the password, then in the next bifam dialog box "Show password".
A dialog box will open in which you must enter the password of the system user on macOS.
