Do iCloud backups save all passwords?

[dragon499]

I generally set up new iPhones from encrypted iTunes backups as I know that all saved WIFI and app passwords are set up. Will setting up (either the same phone or a new one) from an iCloud backup restore all of the passwords as well?

Thanks

For security reasons, after restoring you will likely be prompted to re-enter your passwords for things like your iCloud account, iTunes Store account, mail accounts and Wi-Fi access points. These passwords are stored in the iOS keychain and encrypted using a device-specific key; since a new device has a different device-specific key, these items cannot be decrypted and are therefore unavailable when restoring a backup onto a new device.
