# PFAuthenticationServerLoginWithIOSDeviceIDRequest

> PFAuthenticationServerLoginWithIOSDeviceIDRequest data model. On iOS devices, the identifierForVendor (https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIDevice_Class/index.html# // apple_ref/occ/instp/UIDevice/identifierForVendor) must be used as the DeviceId, as the UIDevice uniqueIdentifier has been deprecated as of iOS 5, and use of the advertisingIdentifier for this purpose will result in failure of Apple's certification process. If this is the first time a user has signed in with the iOS device and CreateAccount is set to true, a new PlayFab account will be created and linked to the vendor-specific iOS device ID. In this case, no email or username will be associated with the PlayFab account. Otherwise, if no PlayFab account is linked to the iOS device, an error indicating this will be returned, so that the title can guide the user through creation of a PlayFab account.
