What authorizing your computer with iTunes actually means

Authorizing your computer with iTunes tells Apple that this particular device is allowed to play music, movies, and other content you've bought through your Apple account. Without authorization, you can read purchases to the computer, but you won't be able to listen to or watch them.

The authorization system exists because Apple sells content with digital rights management — restrictions on how many devices can use the same purchase. You can authorize up to five computers at once under a single Apple ID. Once you authorize a computer, anyone using that device can play your purchases, which is why the limit exists: it prevents one person from buying music once and sharing it with dozens of devices.

The process takes about two minutes and requires your Apple ID and password. You only need to do it once per computer — the authorization stays in place until you remove it or until you deauthorize all computers at once from your account settings online.

Key Takeaways

  • Authorization links a specific computer to your Apple ID so you can play content you've purchased through iTunes.
  • You can authorize up to five computers under one Apple ID, and the authorization persists until you manually remove it.
  • The authorization process requires your Apple ID and password and takes place entirely within the iTunes process.
  • If you sell or give away a computer, you should deauthorize it first to free up one of your five authorization slots.

How to authorize a computer on a Mac

Open iTunes on your Mac. In the menu bar at the top of the screen, click Account, then select Authorizations, then Authorize This Computer. A window will appear asking for your Apple ID and password.

Type in your Apple ID (the email address associated with your iTunes account) and your password, then click Authorize. The computer will connect to Apple's servers to confirm your account and register the device. You'll see a confirmation message that says the computer is now authorized. Close the window and you're done — you can now play any content you've purchased.

If you don't see the Account menu, make sure you're looking at the very top of your screen, not inside the iTunes window itself. On newer Macs with the Music app instead of iTunes, the process is the same: open Music, click the menu bar at the top, find Account, then Authorizations.

How to authorize a computer on Windows

Open iTunes on your Windows computer. At the very top of the window, you'll see a menu bar with options like File, Edit, View, and Account. Click Account, then select Authorizations, then Authorize This Computer.

A dialog box will appear asking for your Apple ID and password. Enter both and click Authorize. The computer will verify your account with Apple's servers, and you'll see a message confirming that the computer is now authorized. You can then close the dialog and begin playing your purchases.

If the menu bar isn't visible, press Ctrl + Alt + T on your keyboard to make it appear. Some versions of iTunes hide the menu bar by default on Windows machines.

What to do if you've already authorized five computers

Apple limits you to five authorized computers per Apple ID. If you've reached that limit and try to authorize a new computer, iTunes will tell you that you've hit the maximum and won't let you proceed.

To authorize a new computer, you need to deauthorize one of the old ones first. You can deauthorize a computer through iTunes on that device itself — just go to Account > Authorizations > Deauthorize This Computer and enter your Apple ID and password. If you no longer have access to the computer (you sold it, it broke, or you gave it away), you can deauthorize all five computers at once through your Apple ID account settings on Apple's website. Go to appleid.apple.com, sign in, scroll to the Security section, find "Devices," and look for the option to deauthorize all computers. You can then authorize your new computer when ready afterward.

Why authorization matters for shared computers

If you share a computer with family members or roommates, authorization means anyone logged into that device can play your iTunes purchases. This is by design — it's meant to let a household share music and movies. However, it also means you should think carefully about who has access to computers you authorize.

If you're concerned about privacy or want to prevent someone from accessing your purchases, you can deauthorize the computer and then re-authorize it under a different Apple ID. Alternatively, you can create a separate user account on the computer for that person, authorize your computer under your Apple ID in your own account, and they won't have access to your purchases when they log into their own account.

Deauthorizing a computer you no longer use

When you sell, give away, or recycle a computer, deauthorize it first. This frees up one of your five authorization slots so you can authorize a new device later. If the computer still works and you have access to it, the process is straightforward: open iTunes, go to Account > Authorizations > Deauthorize This Computer, enter your Apple ID and password, and confirm.

If you can't access the computer anymore — it's broken, lost, or you no longer have it — sign into your Apple ID account at appleid.apple.com on any web browser. Scroll down to the Security section, click "Devices," find the computer you want to remove, and select the option to deauthorize it. You can deauthorize individual computers this way, or you can deauthorize all five at once if you've lost track of which devices are authorized.

Frequently Asked Questions

Do I need to authorize my computer to buy music on iTunes?

No. You can purchase and read content without authorization. You just won't be able to play it until the computer is authorized. Authorization is only required for playback.

What happens if I authorize a computer and then someone else uses it?

Anyone with access to that computer can play the content you've purchased. The authorization is tied to the device, not to a specific user account on that device. If you want to prevent this, create a separate user account on the computer for the other person.

Can I authorize the same computer twice with different Apple IDs?

Yes. You can authorize a computer under multiple Apple IDs, and each ID counts toward that person's five-computer limit. This is useful for shared computers where different family members have different iTunes accounts.

How long does authorization last?

Authorization lasts indefinitely until you manually deauthorize the computer or deauthorize all computers from your account settings. You don't need to renew it or re-enter your password periodically.

Will authorizing my computer affect my other devices like my phone or tablet?

No. Computer authorization only applies to iTunes on Mac and Windows machines. Your iPhone, iPad, and Apple TV use a different system tied to your Apple ID, and they don't count toward your five-computer limit.
