Understanding Authorization


note

You can also move music from your Library that you didn't purchase from the iTunes Music Store into the Purchased Music playlist, but I don't recommend that you do so because that will dilute its purpose.


The music you purchase from the iTunes Music Store is protected in the sense that it has certain limitations on what you can do with it. Fortunately, these limitations are not very limiting!

One of these limits is that you can play iTunes Music Store music on only up to five computers at the same time. To implement this limit, the computer on which you play iTunes Music Store music must be authorized. When you authorize a computer, iTunes will connect to the Internet and register that computer with the iTunes Music Store to play the music purchased under the user account you used to buy it.

To state this another way, you actually authorize the music for a specific user account on up to five computers at a time. When you authorize a computer, you authorize all the songs you have purchased under an iTunes Music Store account; you can't authorize some of the songs you buy on one machine and a different set on another computer. When a computer is authorized, it can play all the music that has been purchased under an iTunes Music Store account. If it isn't authorized, you won't be able to play any of the music you purchased.

note

You can store the music you purchase on as many computers as you'd like. Then you can easily authorize the machines on which you want to play the music and deauthorize the ones you aren't using at the moment.


Fortunately, it is easy to authorize or deauthorize a computer, as you will see in the next sections.

Authorizing a Computer

tip

The five-computer limitation does not apply to iPods. You can use the music you place on these devices as much as you'd like to.


The first time you purchase music on a computer, you must authorize that computer before you can play the music you purchase. After that, the computer remains authorized until you deauthorize it.

To authorize a computer to play purchased music, try to play the music you have purchased from the iTunes Music Store. If the current computer has been authorized, the music will begin to play. If it hasn't been authorized, you will see the Authorize Computer dialog box. Enter the username and password that was used to purchase the music and click Authorize. iTunes will connect to the Internet and authorize the computer. When that process is complete, the music will play.

If you attempt to authorize more than five computers under the same user account, you will see a warning prompt explaining that you can have only five computers authorized at the same time. You must deauthorize one of the computers to be able to authorize the current one.

Deauthorizing a Computer

To deauthorize a computer, select Advanced, Deauthorize Computer. You will see the Deauthorize Computer dialog box (see Figure 26.4). Click the Deauthorize Computer for Music Store Account radio button and click OK. You will see another Deauthorize Computer dialog box. Enter the username (Apple ID or AOL screen name) and password for the account you want to deauthorize on the machine and click OK. iTunes will connect to the Internet and deauthorize the computer. When the process is complete, you will see a dialog box telling you so. Click OK. The computer will no longer count against the five-computer limit for the user account. (It won't be able to play music purchased under that iTunes Music Store account either.)

Figure 26.4. You use this dialog box to deauthorize a computer.


caution

You must be able to connect to the Internet to authorize a computer. This can bite you if you want to play purchased music on a laptop while you are on the road and can't connect. If you didn't purchase music while using that computer, make sure you authorize the machine before you remove it from its Internet connection. If you don't, the purchased music on its hard drive will be only so much dead digital weight until you can authorize that computer.


You can authorize a computer again by attempting to play purchased music and providing the user account and password for which you want to authorize the machine. As you can see, authorizing and deauthorizing computers is simple.
