When you authorize your Mac or PC, you’re giving it permission to access your apps, audiobooks, books, music, movies, and other content. You can authorize up to 5 computers, which means that you can play your content on 5 different computers. You can authorize a computer only through iTunes on that particular computer. You can't authorize a computer from another computer or from your iPhone, iPad, or iPod touch.
What happens if I run out of authorizations?
If one of your 5 authorizations is on a computer you don't use much anymore, deauthorize it. If you've sold or given away a computer that used one of your 5 authorizations, you'll need to deauthorize all of your computers and then re-authorize each one you still use.
If you didn’t deauthorize your computer before reinstalling Windows or upgrading your RAM, hard disk, or other system components, your computer might be using multiple authorizations. Try deauthorizing your computer a few times until it’s no longer authorized, then authorize your computer again, and it will use only one authorization.
How do I know how many computers I've authorized?
If you've authorized 2 or more computers, you can see how many are authorized.
Open your account in iTunes and sign in with your Apple ID. (Or, open iTunes, click Store > Sign In, and enter your Apple ID and password.) In the Apple ID Summary section, you’ll see the number of computers that you’ve authorized with your Apple ID. You can’t see the names of those computers.
Do I need to authorize my iPhone, iPad, or iPod touch?
No. You don’t need to authorize your iPhone, iPad, or iPod touch. Your iOS devices don’t use your available authorizations.
