How can I change my apple id

Greetings, MaryScot.

If you want to change your Apple ID email address, you will need to have access to your account.

"Reset your Apple ID password on the web

If you don't have a trusted device, you can reset your password on the web—but the process might take a little longer.

When possible, the web process redirects you to a trusted device. If you'll have access to one of your trusted devices soon, it might be faster and easier to reset your password then.

If you are unable to reset your Apple ID password, you may need to begin account recovery.

"What is account recovery?

Account recovery is a process designed to get you back into your Apple ID account when you don’t have enough information to reset your password. For security reasons, it might take several days or longer before you can use your account again. We know this delay is inconvenient, but it's important so that we can keep your account and information safe.

Before you start the account recovery waiting period, try to reset your password. Learn how to reset your Apple ID password on a trusted device or through the Apple Support app on a family member’s iPhone, iPad, or iPod touch. You can also visit an Apple Store and ask to use a device on site. If you set up an account recovery contact, they can also help you reset your password.
