Why not have iCloud keychain as default?

Yosemite 10.10.1 and iOS 8.1.2

On my Keychain Access on OS X, I have the "login" default keychain and an "iCloud" keychain (I have iCloud Keychain ON for all my devices).

I'm just wondering, could I just copy all items from "login" to "iCloud" keychain, in order to have it available on my iOS just in case? If that is the case, why wouldn't this be the default behaviour when I "save a password" on my Mac?

Thanks

Solution 1:

Within Keychain Access the 'login' keychain is the user names and passwords that you have stored for the current logged in user. The iCloud keychain is as the title states stored in the cloud available to be accessed on any devices under the same Apple ID.

The main risk with storing anything within a cloud service is the risk of these online services being hacked. OS/X devices are multi user environments, and under these setups often share an iCloud account, or are using iCloud Family Sharing feature. These features could lead to passwords being available to users/family that you would not want to have access to.

As for copying the items over, as far as I am aware there is no way of doing this, looking within Keychain Access application there is no option for this. Also within preferences there is no option to set the default location, any new passwords will be stored within the 'login' keychain.

Hopefully this has cleared things up for you.
