I gone through SO on this topic, it seems there is no clear answer for this question.
I want to know exactly whether the demo account we give on the Appstore submission processs is exactly for Appstore review process or made available to the public use.
Because i am supplying my client's account to the Appstore review process.
Can any one help me on this topic.
Thanks
If your app has a login functionality, you need to create and supply a test/demo account for Apple during review. This account is for App store review purpose only. You can delete this account once the app is approved.
Under iTunes Connect Developer Guide check Providing App Review Information section which says,
Use the App Review Information section to provide contact, review notes, and demo account information so that the App Review team can review your app. If your app requires specific settings, user registrations, or account information before you submit it to the App Store, be sure to include that information in this section.

Hope that helps!
