Part 2:How to Deauthorize Your Computer on iTunes

For various reasons, you need to deauthorize your computer to remove its access to play contents on your iPhone/iPad/iPod for the sake of data security and to prevent it using your available authorization.

  • You're not gonging to use your computer anymore and plan to sell it or give it away.
  • Before you sending your computer for service due to some hardware or system malfunctions.
  • You're going to upgrade some major software or other module.


For deauthorizing your Computer on iTunes, it would depend on how many computer you would like to deauthorize, and you can check how many computer you’ve authorized first to decide the deauthorization.


Deauthorize One Computer

1. Launch iTunes on the computer you want to deauthorize.
2. Mac: Click Store > Deauthorize This Computer
Windows:  Store > Deauthorize This Computer (Hold down Control + B keys to show iTunes menu bar, or click icon in the top right, and then Show Menu Bar)

Show Menu Bar


3. Enter your Apple ID and password when required.
4. Click Deauthorize.


Deauthorize All Computers

When a situation like one of your authorized computer doesn't work anymore or is sold out before de-authorizing it, you will need to deauthorize all of your computers and reauthorize those you’re still using.


1. Open iTunes on one of your authorized computers and log in with your Apple ID and password.

2. Click your name > Account Info, and enter your password again.

3. On the interface of Account Information, scroll to Apple ID Summary and you can see Deauthorize All to the right of Computer Authorizations. Click it to deauthorize all computers.

Deauthorize All Computers



  • Deauthorize All button activates (in blue) only if you’ve authorized 2 or more computers. Otherwise if the button appears in grey, that means you only have one authorized computer.
  • Deauthorize your computer does not cause contents deletion, they still exist in your iTunes Library.
  • You don't need to deauthorize your iDevice, however, you do need to disassociate iPhone/iPad/iPod Touch on iTunes.


After deauthorize all computers you can reauthorize each of them if you want: Open iTunes > Store > Authorize This Computer > Enter Apple ID and password > Click Authorize.


Suppose your exclusive authorized computer doesn't work, what will it happens? As far as I am concerned, there is still solution on iTunes. The only way is that you send email to Apple customer service to ask for help.  May be this is another bug left to be improved by iTunes.  Anyway, the odds seems not so high, so good luck to you!
