An Apple ID is used to access the different services offered by Apple from one central account. For example, you can use your Apple ID for shopping at the Apple Online Store, the iTunes store, the iBookstore and the Mac App Store. Your Apple ID is also used for technical and sales support purposes with the Apple Online Support and when arranging appointments at the Genius Bar with Concierge. Your Apple ID may be automatically disabled for security reasons, such as too many failed attempts to enter the account password. You can use Apple's iForgot website to reset your disabled Apple ID.
Open your Web browser and go to the Apple iForgot website (iforgot.apple.com).
Enter your Apple ID in the "Apple ID" field and click "Next."
Select "Email Authentication" if you want to receive an e-mail with a link to click to reset your password, or select "Answer Security Questions" to provide answers to questions you chose when initially making your Apple ID. Click "Next."
Check your e-mail account for a message from Apple if you selected "Email Authentication," and click the link in the email message. If you selected "Answer Security Questions," provide the answers to the questions and press the "Next" button.
Enter your new password in the "New Password" field and retype it in the "Confirm Password" field. Click the "Reset Password" button.
