Why is the UDID required?


In order to be able to run an app not purchased through the AppStore, the app needs to be signed with a valid developer certificate. This is done by adding your device's UDID (Unique Device Identifier) to our Apple developer account and signing the app to be allowed to run on your device.


Is it safe to share my UDID?


Yes. The UDID can't be used for anything else except signing apps to allow them to run on your device. This is one of Apple's official methods for developers to distribute apps to testers, it's called AdHoc Distribution.
