iosiphonetouch-id
Is there any way I could setup the fingerprint I'd to work in place of typing in my iCloud password whenever prompted, or perhaps even other passwords in keychain?
I had to upgrade to a 5s yesterday and as is the fingerprint id thing seems pretty useless if I can't set it up as a replacement for passwords.
As one can see you have the "Remember Networks this computer has joined" Enabled.
When you join new network, that information is saved in the
com.apple.airport.preferences.plist
located in SystemConfiguration folder.
Obviously iCloud gets that file.
EDIT
Since you asked a new question and want to know how iCloud does that read this. (and click on User defaults database to expand)
Designing for Key-Value Data in iCloud
To store discrete values in iCloud for app preferences, app configuration, or app state, use iCloud key-value storage. Key-value storage is similar to the local user defaults database; but values that you place in key-value storage are available to every instance of your app on all of a user’s various devices. If one instance of your app changes a value, the other instances see that change and can use it to update their configuration.

I just have had the same issue when I try to restore 5S backup into 6. After a few attempts, it eventually worked fine. Here's what I did for the successful try:
It wasn't successful when I tried to restore without reset, or without going through startup config. Hope this helps

If your device is jailbroken, you can install iTouchSecure which lets you use the Touch ID feature for any password entry area in any app, including iCloud password dialogs.
