What authorizing a computer means and why you need to do it

Authorizing a computer for Apple TV means linking that computer to your Apple ID so it can stream video, music, and other content you've bought or rented through iTunes or the Apple ecosystem. When you authorize a computer, Apple's servers recognize it as a trusted device that belongs to you, which lets you read and play content on it without re-entering your password every time.

You need authorization because Apple limits the number of computers that can play content you've purchased. You can authorize up to five computers per Apple ID at any given time. This protects your account from unauthorized use while still letting you watch or listen on multiple devices in your household.

The authorization process is straightforward and takes just a few minutes. Once a computer is authorized, it stays that way until you manually deauthorize it or until you deauthorize all computers at once from your account settings.

Key Takeaways

  • Authorizing a computer links it to your Apple ID and lets it play content you've purchased through iTunes or Apple services.
  • You can authorize up to five computers per Apple ID, and authorization stays active until you remove it.
  • On a Mac, open iTunes or the Music app, go to Account menu, and select Authorize This Computer.
  • On Windows, open iTunes, go to Account menu, and select Authorize This Computer, then enter your Apple ID and password.
  • If you've reached your five-computer limit, you must deauthorize a computer before authorizing a new one.

How to authorize on a Mac

On a Mac running macOS Monterey or later, the process depends on which app you're using. If you use the Music app (the default on newer Macs), open it and click Music in the menu bar at the top of your screen. Then select Account and choose Authorize This Computer. A window will appear asking for your Apple ID and password—enter both and click Authorize.

If you're using an older Mac with iTunes instead, open iTunes and click iTunes in the menu bar. Select Account, then Authorize This Computer. Enter your Apple ID credentials and click Authorize. The computer is now linked to your account and can play your purchased content.

After authorization, you won't see a confirmation message—the window straightforward closes. Your computer is ready to use. You can verify it worked by going back to Account and checking whether the Authorize option has changed to Deauthorize This Computer.

How to authorize on Windows

On a Windows computer, you need iTunes installed. Open iTunes and click Account in the menu bar at the top. Select Authorize This Computer from the dropdown. A dialog box will open asking for your Apple ID and password.

Enter your full Apple ID (usually your email address) and your password, then click Authorize. Windows will connect to Apple's servers to verify your account. Once the connection is confirmed, the dialog closes and your computer is authorized.

Like on Mac, there's no success message—the closed dialog means it worked. To confirm, return to Account menu and check that Deauthorize This Computer now appears instead of Authorize.

What to do if you've already authorized five computers

Apple limits you to five authorized computers per Apple ID. If you try to authorize a sixth computer, you'll see an error message saying you've reached your limit. To authorize the new computer, you must first deauthorize one of the existing five.

You can deauthorize computers one at a time by opening iTunes or Music on each computer, going to Account, and selecting Deauthorize This Computer. You'll need to enter your Apple ID and password again. Alternatively, you can deauthorize all computers at once from your Apple ID account settings on the web—go to appleid.apple.com, sign in, scroll to Security, and select Deauthorize All.

Deauthorizing all computers at once is useful if you've sold or given away old computers and lost track of which ones are still authorized. After you deauthorize all, you can then authorize your current computers fresh. Keep in mind that deauthorizing all computers removes authorization from every device linked to your account, so only do this if you're ready to re-authorize the ones you actually use.

Why authorization might fail

Authorization fails most often because of an incorrect Apple ID or password. Double-check that you're entering the right email address and that Caps Lock is not on. If you've recently changed your Apple ID password, use the new one.

Network connection problems can also block authorization. Make sure your computer is connected to the internet and that your firewall or antivirus software isn't blocking iTunes or Music from reaching Apple's servers. Try restarting your computer and attempting authorization again.

If you see a message saying your account has been locked for security reasons, visit iforgot.apple.com to unlock it before trying again. If authorization still fails after checking these things, restart iTunes or Music completely and try once more.

Deauthorizing a computer you no longer use

When you sell, give away, or stop using a computer, deauthorize it to free up one of your five slots. Open iTunes or Music on that computer, go to Account, and select Deauthorize This Computer. Enter your Apple ID and password when prompted.

If you no longer have access to the computer—for example, if it was stolen or you've already sold it—you can deauthorize it remotely. Sign in to appleid.apple.com on any web browser, go to Security, and select Manage under Devices. Find the computer in the list and click Remove. This deauthorizes it without needing the computer itself.

Deauthorizing removes that computer's ability to play your purchased content, but it doesn't delete anything from the computer. Any files already downloaded to it will remain, but the computer won't be able to play protected content after deauthorization.

Frequently Asked Questions

Do I need to authorize my computer to watch Apple TV+?

No. Apple TV+ streams through the Apple TV app and doesn't require computer authorization. You only need to sign in with your Apple ID in the app itself. Authorization is only needed for content you've purchased or rented through iTunes.

What happens if I don't authorize my computer?

Without authorization, you won't be able to play movies, TV shows, or music you've purchased through iTunes on that computer. You can still stream services like Apple TV+ or Apple Music, but not owned content. Authorization is free and takes two minutes.

Can I authorize the same computer twice?

No. Once a computer is authorized to your Apple ID, it stays authorized until you deauthorize it. You don't need to repeat the process. If you reinstall your operating system, you'll need to authorize again.

How long does authorization last?

Authorization lasts indefinitely until you manually deauthorize the computer or deauthorize all computers from your account settings. It doesn't expire after a certain time period.

Can I authorize a computer for someone else's Apple ID?

No. You can only authorize a computer to the Apple ID you're signing in with. If someone else wants to use their own purchased content on your computer, they would need to authorize it with their own Apple ID, but that counts against their five-computer limit.
