The issue with CloudKit web services is the authentication. Who use CloudKit from browser or from a web component on Android, will not have Apple ID, so they have to go though the registration process.
- choose Apple ID
- set birthday
- set first / last name
- optionally set an e-mail
- set three control questions for remembering (!!!)
It totally breaks the workflow on web and Android. Nowadays people don't waste time register on a site, especially when registration is so long.
Any way to register an Apple ID based on FaceBook login button?
