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.
How to add or remove trusted phone numbers on an iPhone and iPad
The first time you enable 2FA on your Apple account, the phone number you use with your iPhone is automatically registered as a trusted number. However, you can follow these simple instructions to add, remove, or update a trusted phone number on your iOS or iPadOS devices:
Go to settings on your iPhone or iPad.
In Settings, tap your Apple ID name, is at the top.
Next, choose Password & security from your Apple ID settings.
Here you can see your current trust number. Tap on To edit next to the trusted phone number.
Now tap on Add a trusted phone number to get started.
You need to enter yours Device passcode to authenticate the process.
Next, select the country code and enter the number. You can confirm your number either by SMS or by phone. When you're done, tap Send.
At this point, all you have to do is enter the verification code you will receive to register this new phone number as a trusted phone number. And when you're done, consider using this alternate method to log into your Apple account with 2FA.
How to add or remove a trusted phone number on Mac
If you're reading this on your Mac, there is a similar way to update your trusted phone number in macOS too. Assuming you have a 2FA enabled Apple account, here's what you need to do:
Go over to System settings on your Mac.
Click on Apple ID in the upper right corner of the window.
This should show your Apple ID settings. Choose Password & security from the left pane.
Here you will find the Trusted Phone Numbers section on the right. Click on To edit Besides.
You will now see your current phone number along with the option to add a new one. Tap that Plus (+) Icon to get started.
Next, you'll need to enter your Mac's user password before entering the new phone number and country code.
You will receive a verification code on your new phone number for verification, which you can then use as a backup method to sign in to your Apple account from new devices.
A trusted phone number helps you sign in without a trusted device
Using a trusted phone number is your only option if you don't have access to a trusted device like your iPhone, iPad, or Mac. Also, Apple's 2FA popups can sometimes fail and take a long time to appear. In such cases, a simple text message with the verification code would be a faster way to sign in to your Apple account.
And if you use multiple phones, you can add multiple trusted numbers to make sure you never get locked out of your account.
