What authorizing a computer means for Apple Music

Authorizing a computer for Apple Music means telling Apple that this specific device is allowed to play music you've purchased or subscribed to. When you authorize, you're connecting your Apple ID to that computer so the Music app (or iTunes, on older systems) recognizes you as the account owner and grants access to your library.

You need to authorize because Apple limits how many devices can play your music at the same time. Without authorization, the app won't know who you are or whether you have permission to listen. Authorization is free and takes less than a minute — it's just a security step that protects your account and your purchases.

Key Takeaways

  • Authorization connects your Apple ID to a computer so the Music app knows you own the account and can access your library.
  • You can authorize up to five computers at once; if you need more, you must deauthorize an old one first.
  • The authorization process is different on Mac and Windows, but both take about one minute.
  • If you sell or give away a computer, deauthorize it before you hand it over so the new owner can't access your music.

How to authorize on a Mac

Open the Music app and look at the menu bar at the top of your screen. Click Music, then scroll down to find Account. A dropdown menu will appear — select Authorize This Computer.

A window will pop up asking for your Apple ID and password. Type both in and click Authorize. The app will confirm that your computer is now authorized. You're done — you can now play music from your library on this Mac.

How to authorize on Windows

Open iTunes (the app you use for music on Windows computers). At the top of the window, click the Account menu. Select Authorize This Computer from the dropdown.

Enter your Apple ID and password when prompted, then click Authorize. iTunes will confirm the authorization is complete. Your Windows computer can now access your Apple Music library and any music you've purchased.

The five-computer limit and what to do when you hit it

Apple lets you authorize up to five computers at the same time. If you try to authorize a sixth computer, the system will stop you and ask you to deauthorize one of the others first.

To deauthorize a computer you no longer use, open the Music app (or iTunes on Windows), go to Account, and select Deauthorize This Computer. Enter your Apple ID and password. That computer is now removed from your account, and you can authorize a different one. If you've sold or given away a computer, you can also deauthorize it remotely from any authorized computer by going to Account > Deauthorize All — though this removes authorization from every computer at once, so you'll need to re-authorize the ones you still own.

Why you need to authorize before you can play music

Authorization is a security measure. It prevents someone else from using your Apple ID to read or stream music without your permission. It also keeps track of how many devices are using your account at once, which protects both you and Apple's licensing agreements with music publishers.

Without authorization, the Music app has no way to know whether you're the account owner or someone who borrowed the computer. The app will refuse to play protected music — anything you've purchased or anything from an Apple Music subscription — until you prove who you are by signing in with your Apple ID.

What happens if you don't authorize

If you try to play music without authorizing, the app will show an error message saying the computer is not authorized. You won't be able to listen to purchased music or stream from Apple Music. The only way forward is to authorize the computer using the steps above.

If you're borrowing someone else's computer, you can ask them to authorize it with their Apple ID, but then they'll be the one who can play music — not you. For your own music, you need your own Apple ID authorized on that device.

Deauthorizing when you sell or give away a computer

Before you hand over a computer to someone else, deauthorize it so the new owner cannot access your music library or make purchases using your account. Open the Music app, go to Account, and select Deauthorize This Computer. Enter your Apple ID and password.

Once deauthorized, the new owner can authorize the computer with their own Apple ID and use it freely. This protects your account from unauthorized access and prevents your music from being tied to a device you no longer control.

Frequently Asked Questions

Can I authorize the same computer twice?

No. Once a computer is authorized with your Apple ID, it stays authorized until you deauthorize it. If you want to switch to a different Apple ID on the same computer, you must deauthorize first, then authorize again with the new ID.

What if I forgot my password?

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

Do I need to authorize every time I open the Music app?

No. Once you authorize a computer, it stays authorized until you deauthorize it or sign out of your Apple ID. You won't need to enter your password again unless you sign out or the authorization expires.

Can I authorize a computer that doesn't have an Apple ID yet?

You need an Apple ID to authorize any computer for Apple Music. If you don't have one, you can create one free at appleid.apple.com. Once you have an ID, follow the authorization steps above.

What if I lost access to one of my authorized computers?

If you can't reach a computer you authorized — because you lost it, it broke, or you no longer have it — you can deauthorize it remotely. From any other authorized computer, open the Music app, go to Account > Deauthorize All, enter your password, and all computers will be deauthorized at once. Then re-authorize the computers you still own.
