How do I change my contact info on my apple id

To see, add, or change your trusted phone numbers:

- On a Mac: Choose Apple menu  > System Settings (or System Preferences), then click your name (or Apple ID). Click Password & Security, then add or remove a trusted phone number.

- In a web browser: Go to the Account Security section of https://appleid.apple.com/
