What authorizing a computer for iTunes actually means

Authorizing a computer for iTunes means telling Apple that this specific device is allowed to play music, movies, and other content you've bought from the iTunes Store using your Apple ID. When you buy something from iTunes, Apple attaches it to your account — not to the file itself. Authorization is the step that lets your computer decrypt and play that content.

Without authorization, you can still see your purchases in iTunes, but you cannot play them. You can authorize up to five computers at once on a single Apple ID. Once you hit that limit, you have to deauthorize an old computer before you can authorize a new one.

This system exists because Apple wants to prevent one person from buying music once and sharing it with dozens of devices. It is not about preventing you from using your own purchases on your own devices — it is about limiting how many of your devices can use one purchase.

Key Takeaways

  • Authorization connects your computer to your Apple ID so iTunes can verify you own the content you are trying to play.
  • You can authorize up to five computers per Apple ID, and you must deauthorize an old one before adding a sixth.
  • The authorization process takes less than a minute and requires only your Apple ID and password.
  • If you sell or give away a computer, deauthorizing it prevents the new owner from playing your iTunes purchases.

How to authorize a computer running iTunes on Windows or Mac

Open iTunes on the computer you want to authorize. In the menu bar at the top of the screen, click Account (on Mac) or Edit (on Windows). A dropdown menu will appear.

Select Authorize This Computer from the menu. A window will pop up asking for your Apple ID and password. Type in the email address or phone number associated with your Apple ID, then enter your password. Click Authorize. The computer is now authorized, and you can play your iTunes purchases when ready.

If you have two-factor authentication turned on for your Apple ID — which Apple recommends — you may be asked to enter a verification code sent to one of your trusted devices. This is a security step. Enter the code when prompted, and authorization will complete.

What to do if you cannot find the Authorize option

If you are using a newer Mac with Apple Music or the Music app instead of iTunes, the authorization process works differently. Open the Music app, then go to Account in the menu bar and select Authorize This Computer. The steps are the same from there.

On Windows, if you have iTunes version 12.1 or later, the menu structure may be slightly different. Look for Edit in the menu bar. If you do not see a menu bar, press Ctrl + B to make it visible. Then follow the same steps: click Edit, then Authorize This Computer.

If the option still does not appear, make sure you are signed into iTunes with your Apple ID. You cannot authorize a computer if you are not logged in. Click Account or Edit and look for a Sign In option. Sign in first, then try authorizing again.

How to deauthorize a computer you no longer use

If you have reached the five-computer limit or you are selling or giving away a device, you need to deauthorize it. Open iTunes on that computer, go to Account (Mac) or Edit (Windows), and select Deauthorize This Computer. Enter your Apple ID and password when prompted. The computer is now deauthorized and can no longer play your iTunes purchases.

If you no longer have access to the computer — for example, you sold it or it was stolen — you can deauthorize it remotely. Go to appleid.apple.com in a web browser and sign in with your Apple ID. Click Devices, find the computer you want to remove, and select Remove from Account. This deauthorizes it without needing the physical device.

Apple allows you to deauthorize all five computers at once, but only once per year. If you need to do this, go to your Apple ID account settings online, find the option to deauthorize all computers, and confirm. Use this option only if you have lost track of which devices are authorized or if you suspect unauthorized access to your account.

Why authorization matters for your privacy and security

Authorization is a privacy boundary. When you authorize a computer, you are telling Apple that device can access your iTunes library and your purchase history. If someone else uses that computer, they can see what you bought and play those purchases. This is why deauthorizing matters when you sell a device or let someone else use it regularly.

Authorization also protects your account from unauthorized use. If someone gains access to your Apple ID password, they could authorize their own computer to play your purchases. Checking your authorized devices regularly — through your Apple ID account settings — lets you spot devices you do not recognize and remove them.

What happens if you authorize too many computers

If you try to authorize a sixth computer, iTunes will tell you that you have reached the limit. You will see a message saying you must deauthorize another computer first. You cannot work around this limit by using a different Apple ID on the same device — each Apple ID has its own five-computer limit.

This limit resets once per year. If you deauthorize a computer and then want to re-authorize it within the same year, you can do so without hitting the limit again. But if you have deauthorized and re-authorized five different computers in one year, you will have to wait until the year rolls over to authorize a sixth.

Frequently Asked Questions

Do I need to authorize my computer if I only use Apple Music, not iTunes purchases?

No. Apple Music is a streaming service, so authorization is not required. You only need authorization if you have bought music, movies, TV shows, or other content from the iTunes Store and want to play it on that computer.

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

Yes. A single computer can be authorized with up to five different Apple IDs. Each ID can authorize up to five computers, so the limits work independently. This is useful if multiple people in a household buy content from iTunes.

What if I forgot which computers I have authorized?

Sign into your Apple ID account at appleid.apple.com, click Devices, and you will see a list of all authorized computers and devices. You can remove any device from this list without needing access to the physical computer.

Does authorizing a computer give someone access to my other Apple services?

No. Authorization only controls access to iTunes purchases on that specific computer. It does not give access to your email, iCloud files, or other Apple services. Those require separate sign-in and authentication.

Can I authorize a computer that is not connected to the internet?

No. Authorization requires an internet connection so iTunes can contact Apple's servers and verify your Apple ID. Make sure your computer is online before you attempt to authorize it.
