We get more frequent questions about Apple IDs than almost anything else, so if you're not clear on what the Apple ID is, you are in good company! Your Apple ID is a username that identifies you to Apple (and all of their devices and services you use), and it is typically your email address. You will also have a password associated with your ID that is distinct to your Apple ID, and not the same as the password you use to log in to your email address (except in very rare cases).
