This tutorial shows you how to delete your Apple ID or iCloud account. But first, it’s essential to know about the consequences of such action, what will stop working, and what you must do before deleting your Apple ID to prevent your devices from becoming unusable!

Why delete your Apple ID?

• You have a second Apple ID and wish to stop using the first one.
• You migrated to non-Apple platforms like Android or Windows PC and no longer use or plan to use Apple devices.
• You have privacy concerns with Apple.

This is serious business. The consequences are severe. Measure twice, cut once, caveat emptor, etc.

But if you have a good reason, read through Ankur’s tutorial, proceed with caution.
