You're going to need to have your login information handy if you want to make the move to iOS 9.1 right away.
In order to get the installation process going, you'll need the device's passcode. So if you're installing it for a friend or family member, make sure you get that code otherwise you won't be able to get the download process started. You'll also want to track down your Apple ID and iCloud login information. We were prompted to input our Apple login after installing the update and we moved from iOS 9.0.2. One other thing. You'll also want to have your logins for your various applications handy. If you're moving from iOS 8 to iOS 9.1, you'll likely get logged out of most, if not all, of your applications. So make sure you have all of that info on hand before you make your move.
