Change the Trusted Telephone Quantity for Your Apple ID

Apple uses a trusted phone number to verify your identity when you sign in with your Apple ID. Here's how to turn it on from an iPhone, iPad, or Mac.

If you switch to a different provider, you may want to change the trusted phone number that is associated with your Apple ID. It's handy for two-factor authentication and ensures you're not completely locked out of your account.

You can also add multiple trusted phone numbers to your account if you have more than one phone. Apple makes it easy to do right from your iPhone, iPad, and even your Mac. Here we look at how to update the trusted phone number in iOS and macOS.

What is a trusted phone number?

A trusted phone number is simply a phone number that Apple uses to verify your identity when you sign in to a new device with your Apple account. It acts as a second layer of security for Apple's two-factor authentication system (2FA).

When you sign in to your Apple ID account from a new device, you usually get the 2FA prompt on your trusted devices. However, if that doesn't work or you don't have access to your trusted device, you can ask Apple to send a verification code as a text message to your trusted phone number.
