Method 2 of 2: Method 2: Revoke the permissions of all computers

   • You can only perform this method once every 12 months.
2. Click on your Apple ID. This can be found in the top left of the iTunes window. If you are not yet logged in, click the "Account" button and enter your details. Click this button again, enter the password and click "View account".
3. In the "Account Information" window, click "Revoke All Permissions". The permissions of all devices associated with your Apple ID have now been revoked.
