I am wondering how best to identify a device so we can store the user's ID and Password (not using .ini) and retrieve that info when they log in using the Device ID.
i.e. When the user launches the app it connects to a DB, then pulls the device ID from the mobile device and uses it to retrieve the store User ID and Password from the DB based on the device ID.  Should work well...but:

1. Is the device ID unique to all devices (i.e. Apple IPhone, IPad and Android/Samsung) or is it only unique by manufacturer?

2. If it is not unique, can one use the device name combined with the device id.

I was also reading that the Apple store does not any longer accept App's that access the UDID.  Does the of_GetDeviceID function access this ID?

Here's what I found on the Web about the UDID.

'UDID (aka Universal Device ID) – this was the old unique identifier for iOS. It is no longer used and has been replaced with the iOS IDFA ID. Apple no longer accepts apps in their store that access this identifier'

Thank you,
