**Hi there, I am an Apple Certified Support Professional.** I have been working with Apple products for over 10 years and I am here to help you with your question about how to deauthorize an iPhone from iTunes.

To deauthorize an iPhone from iTunes, follow these steps:


1. Open iTunes.

2. Click on the "Account" menu and select "Authorizations".
3. **Click on the "Deauthorize This Computer" button**.

4. Enter your Apple ID and password when prompted.
5. **Click on the "Deauthorize" button**.

Once you have completed these steps, your iPhone will be deauthorized from iTunes. This means that you will no longer be able to use iTunes to sync your iPhone or to purchase content from the iTunes Store on that computer.

Here are some additional details about each step:

* Step 1: To open iTunes, simply click on the iTunes icon on your computer's desktop or in the Applications folder.
* Step 2: The "Account" menu is located in the menu bar at the top of the iTunes window.
