If you’re about to leave a job or abandon an address, make changes first.
Apple lets you register an Apple ID using an email address it offers or with what it calls a “third-party” address—that’s one from any other service. In the latter case, if you use an email address for a personal Apple ID account and you know you’ll lose access to that address—maybe you’re about to quit a job, retire, be laid off, or, gulp, be fired!—you should make sure and change it now or ensure future access.
For these third-party addresses, it’s an easy change. Apple lets you simply pick another address to use, and then you confirm the receipt of a message at that address so Apple can be sure the new address is under your control.
- Go to the Apple ID site and log in.
