Manage your account

You can manage your trusted phone numbers, trusted devices, and other account information from your Apple ID account page.

Keep your trusted phone numbers up to date

To use two-factor authentication, you need at least

one trusted phone number on file where you can receive verification

codes. Consider verifying an additional trusted phone number other than

your own phone number. If your iPhone is your only trusted device and it

is missing or damaged, you will be unable to receive verification codes

required to access your account.

You can update your trusted phone numbers when you follow these steps:

1. Go to your Apple ID account page.
2. Sign in with your Apple ID.
3. Go to the Security section and click Edit.
