One device for multiple IOS Developer Program Accounts

Question

If i register device(in my Developer Account), that belongs to my company and registered in their iOS Developer Account, do they have possibility to know about that (and cut my head:)?

Answer 1

No, there's no way for them to find out what third-party programs or provisioning profiles a device is registered with.

Answer 2

If they go to Settings > General > Profiles on the device, they will see your developer account profile in there if you don't delete it every time.

But other than that, they can't discover this information from their developer account.
