Deauthorizing iTunes: A Complete Guide

iTunes Authorization Management
The iTunes platform employs an authorization mechanism designed to restrict access to your acquired music, videos, and other digital media to a limited number of computers concurrently.
Before disposing of a computer or undertaking a Windows reinstallation, it is crucial to deauthorize iTunes. This process ensures your authorization slots remain available for use on your active devices.
Understanding iTunes Authorization
This authorization system functions as a form of Digital Rights Management (DRM). Consequently, managing it can sometimes require several steps.
The primary intention behind this system is to safeguard your purchased content by limiting where it can be accessed.
Why Deauthorize?
- Computer Disposal: Releasing the authorization allows another user to utilize iTunes with their own account.
- Operating System Reinstallation: A fresh OS install necessitates re-authorization of iTunes.
- Preventing Access Issues: Deauthorizing unused computers prevents potential problems with accessing your purchases on authorized devices.
Properly managing your iTunes authorizations is essential for a seamless user experience and maintaining control over your digital library. It's a preventative measure to ensure continued access to your legally obtained content.
Understanding iTunes Authorization
Before a computer, whether a Mac or a Windows PC, can download and utilize your iTunes purchases – including films, television programs, music, eBooks, audiobooks, applications, and other media – it needs to be authorized within iTunes. It’s important to note that this requirement applies solely to content protected by Digital Rights Management (DRM).
A significant portion of music available on iTunes is DRM-free, meaning computer authorization isn’t necessary for playback.
Your Apple ID is limited to a maximum of five authorized computers concurrently. This count encompasses both Macintosh and Windows-based personal computers.
Device Limitations and DRM
iOS devices, such as iPhones, iPads, and iPod Touches, do not contribute to the five-device authorization limit. Consequently, you can connect an unlimited number of Apple’s mobile devices to your iTunes content.
The iTunes authorization process represents a form of DRM, designed to control access to your purchased media. Similar systems were prevalent in the past, like SecuROM for PC games or activation limits within Windows Media files.
Many modern services now focus on restricting content to specific accounts rather than limiting the number of devices. However, iTunes continues to employ this older method of authorizing and deauthorizing individual computers.
It’s plausible that these limitations were established through contractual agreements between Apple and content providers when iTunes was initially launched.
Computer Authorization ProceduresThe process of authorizing a computer is straightforward. For Windows users, navigate to the iTunes menu, select "iTunes Store," and then choose "Authorize This Computer." Mac users should click the "Store" menu and subsequently select "Authorize This Computer."
Authentication is achieved by logging in with your registered Apple ID.
Benefits of Authorization
Upon successful authorization, your computer gains the capability to download, synchronize, and play content previously purchased through iTunes.
This ensures a seamless experience with your digital media library.
- Downloads become accessible.
- Content synchronization is enabled.
- Playback of purchased items is permitted.
The authorization process safeguards your purchased content and allows for its use on trusted devices.
When and How to Revoke Computer Authorization for iTunes
Within the iTunes account settings, a "Deauthorize This Computer" function is readily available. Selecting this option effectively removes authorization, thereby restricting access to DRM-protected iTunes media on that specific machine.
This prevents the playback, viewing, or downloading of content secured with Digital Rights Management.
It is recommended to deauthorize your computer prior to uninstalling iTunes. Furthermore, doing so is crucial before a Windows reinstallation or when permanently retiring a device.
If you no longer intend to utilize your purchased iTunes content on a particular computer, deauthorization is the appropriate course of action.
Apple specifically recommends deauthorizing before significant hardware upgrades. Failure to do so may cause the system to be recognized as a new computer, consuming additional authorizations.
Deauthorization is a vital step as it recovers one of your limited five device authorizations for reuse.
Consider this process a way to manage your iTunes account and ensure your purchased content remains accessible on your authorized devices.

Addressing iTunes Authorization Issues on Inaccessible Devices
Situations arise where you may have exhausted your authorized devices for iTunes. This can occur if a computer malfunctions and becomes inaccessible for deauthorization, if a device is disposed of prior to the process, or following significant hardware upgrades.
These previously authorized systems continue to occupy slots within your five-device limit. Repeated authorizations coupled with the loss of access to authorized computers, or frequent operating system reinstalls, can ultimately prevent you from accessing your iTunes purchases.
The Single Solution Offered by Apple
Apple provides a single method for resolving this issue. A direct list of authorized devices for individual deauthorization isn't available. Instead, a complete deauthorization of all computers is required.
To initiate this process, navigate to the iTunes Store within iTunes. Sign in using your Apple ID credentials. Then, select your Apple ID name and choose the 'Account' option.

Within the Account section, locate and click the 'Deauthorize All' button, found next to 'Computer Authorizations'. This option will only be visible if more than one computer is currently authorized.
Selecting this button immediately revokes authorization from all linked devices, enabling you to re-authorize your computers from the beginning.
Important Note: The 'Deauthorize All' function is limited to once-per-year usage. Following its use, exercise caution with future authorizations – always deauthorize devices before disposal, OS reinstalls, or hardware modifications.

If you encounter difficulties accessing your purchased content, or have already utilized the 'Deauthorize All' feature within the current year, contacting Apple Support is recommended. They may be able to manually reset your authorizations.
This represents the only available recourse, aside from circumventing the Digital Rights Management (DRM) system.
