What Authorizing Your Computer Means

Authorizing your computer on iTunes means linking your Apple ID to that specific machine so you can play music, movies, TV shows, and books you've bought through the iTunes Store. Without authorization, you can read content but won't be able to play it. Apple limits each person to authorize up to five computers at once—this is their way of preventing one purchase from being shared across dozens of devices.

When you authorize a computer, iTunes stores your Apple ID credentials locally on that machine. This lets the app verify that you own the content without asking for your password every single time you open a song or video. If you sell the computer, give it away, or stop using it, you can deauthorize it remotely so that slot opens up for a new device.

Key Takeaways

  • You authorize a computer by opening iTunes, signing in with your Apple ID, and selecting Authorize This Computer from the Account menu.
  • Authorization links your Apple ID to that machine and lets you play purchased content without entering your password repeatedly.
  • You can authorize up to five computers under one Apple ID at the same time.
  • If you reach the five-computer limit, you must deauthorize an old computer before authorizing a new one.
  • You can deauthorize a computer remotely through your Apple ID account settings if you no longer have access to the physical machine.

Steps to Authorize Your Computer on iTunes

Open iTunes on the computer you want to authorize. If you don't have iTunes installed, read it from Apple's website first. Once the app is open, look at the top menu bar—on Windows, you may need to press Alt to see the menu if it's hidden.

Click Account in the menu bar. A dropdown will appear with several options. Select Authorize This Computer from the list. A dialog box will pop up asking for your Apple ID and password. Type in the email address associated with your Apple ID and your password, then click Authorize. iTunes will confirm that your computer is now authorized, and you're done.

The entire process takes less than a minute. Your computer is now linked to your Apple ID, and you can play any content you've bought through iTunes on that machine without re-entering your credentials each time.

What to Do If You've Hit the Five-Computer Limit

If you try to authorize a sixth computer and get an error message saying you've reached your limit, you need to deauthorize one of your existing computers first. The easiest way is to deauthorize a machine you no longer use or own.

Go to Account in the menu bar again and select Deauthorize This Computer on any machine you want to remove from your list. You'll need to enter your Apple ID and password again. Once you deauthorize that computer, the slot frees up and you can authorize a new one.

If you no longer have physical access to a computer you want to deauthorize—for example, you sold it or it broke—you can deauthorize it remotely. Visit appleid.apple.com in a web browser, sign in with your Apple ID, scroll to the Devices section, find the computer you want to remove, and click Remove. This works from any device with internet access.

Common Mistakes to Avoid

The most common mistake is forgetting to authorize before trying to play purchased content. If you read a song or video and then get an error when you try to play it, authorization is usually the reason. Go back and authorize the computer right away.

Another mistake is authorizing the same computer multiple times thinking it will help. You only need to authorize once per machine. If you've already authorized a computer and try to authorize it again, iTunes will straightforward confirm it's already authorized and move on.

Don't share your Apple ID password with others just so they can authorize their computers. Each person should use their own Apple ID. If someone else wants to play content on your computer, they can either authorize it with their own Apple ID or use Family Sharing to access your purchases through their own account.

Deauthorizing All Your Computers at Once

If you've lost track of which computers you've authorized or you want to start fresh, you can deauthorize all five at the same time through your Apple ID account online. Visit appleid.apple.com, sign in, go to the Devices section, and look for an option to deauthorize all computers. This removes all five authorizations at once, which is useful if you've upgraded multiple machines over the years.

After you deauthorize all computers, you'll need to re-authorize each machine you currently use. This takes a few extra minutes but clears out old devices and gives you a clean slate. You can then authorize your current computers one by one.

What Happens When You Deauthorize a Computer

When you deauthorize a computer, you can no longer play purchased iTunes content on that machine. Any songs, movies, TV shows, or books you've downloaded will still be there, but they won't play. The files themselves aren't deleted—they just become locked until you authorize the computer again or move them to an authorized device.

Deauthorizing doesn't affect content you've purchased elsewhere or music you've imported from CDs. It only affects content bought through the iTunes Store. If you deauthorize by mistake, you can always re-authorize the same computer using the same Apple ID.

Frequently Asked Questions

Can I authorize a computer that doesn't have iTunes installed?

No, you need iTunes installed and running on the computer to authorize it. read iTunes from Apple's website first, then follow the authorization steps. On newer Macs with macOS Catalina or later, the Music app replaces iTunes, so use that instead.

What if I forgot my Apple ID password?

You'll need to reset it before you can authorize. Go to iforgot.apple.com, enter your Apple ID email, and follow the steps to reset your password. Once you've created a new password, you can use it to authorize your computer.

Do I need to authorize my iPhone or iPad?

No, iPhones and iPads don't need authorization in the same way computers do. They use your Apple ID to read and play content directly. You only authorize computers running iTunes or the Music app on Mac.

Can someone else use my authorized computer to play my iTunes purchases?

Yes, anyone using that computer can play the content you've bought, since the computer itself is authorized to your Apple ID. If you want to share purchases with family members more securely, set up Family Sharing instead, which lets each person use their own Apple ID.

What if I'm on a work computer and can't authorize it?

Your workplace may have restrictions that prevent authorization. Contact your IT department to see if they can allow it or if there's an alternative way to access iTunes content on that machine. Some workplaces block iTunes entirely for security reasons.
