The idea is simple: If you connect to a Wi-Fi network on your Android phone, your Chromebook will automatically know your password. This works the other way around, too. The devices share Wi-Fi credentials as long as you're both using the same Google account.
To use Wi-Fi Sync, you'll first need to connect your Android phone to your Chromebook. Set up the “Phone Hub” feature to connect your device (and access a few other handy features).

With your Android device connected to your Chromebook, we can now get started with the Wi-Fi Sync feature. First, click on the clock in your Chromebook’s navigation bar (known as the “Shelf”) to bring up the “Quick Settings” panel. Select the gear icon to open the Settings menu.
In the Settings menu, go to the “Connected Devices” tab in the sidebar.
Since we've already connected your phone, it will appear in the “Connected Devices” section. Select it to continue.

Then, look for “Wi-Fi Sync.” The toggle will likely be grayed out (as shown below). Click the “Chrome Sync” link to go to its settings.
Select the “Turn On” button at the top of the screen. Now, you can toggle the switches for anything you want to sync between Chromebooks. The only thing you need to turn on for Wi-Fi sync is “Wi-Fi Networks.”.
Now we can return to the previous screen and “Wi-Fi Sync” will be enabled.
After you enable Wi-Fi Sync on your Chromebook, a notification will appear on your connected Android phone. It may take a few minutes for it to appear, but once it does, tap the notification.
Here you can turn the feature off or on from your phone. There is also an option to “Forget Chromebook”.

To get to this screen from Android settings, go to Connected Devices > Connection Preferences > Chromebook.
Wi-Fi networks and passwords will now be shared between your devices. This will result in less password typing, which is always a good thing.
