A trusted device is an iPhone, iPad, or Mac, where you have previously signed in using yourApple ID. Trusted devices are used to verify your identity when signing in and keep your Apple ID secure with two-factor authentication.
In this tutorial, we will go over trusted devices for Apple ID two-factor authentication, their requirements, and some other pieces of valuable information that you should know.
What’s two-factor authentication in Apple ID?
A computer or system can identify you by asking one of these:
Using at least two of the above factors to confirm identity is considered excellent. This way, the computer verifies your identity at a multi-level, ensuring it’s genuinely you who is trying to gain access. This is calledtwo-factor authentication(2FA).Source:Tom Scott’s must-watch video
Apple uses two-factor authentication to secure your Apple ID and its data.
Suppose you try to log in to your Apple ID from a friend’s computer. You enter your Apple ID email and the correct password (something you know). As an additional layer of protection, Apple will send you a six-digit code on your trusted device or trusted phone number (something you have). Once you enter this code, you have successfully verified yourself at two levels. After this, you are logged in.
In summary, two-factor authentication protects your Apple ID and ensures no one can get unwarranted access to it, even if they have your Apple ID password. 2FA is built into the core of Apple operating systems like iOS and macOS.

What’s a trusted device?
A trusted device is an iPhone, iPad, or Mac that Apple knows is yours. Apple can send a verification code to these trusted devices to confirm your identity when you try to sign in from a new/different device or browser.
Trusted devices can also generate offline verification codes.
What’s a trusted phone number?
Like trusted devices, trusted phone numbers are added to your Apple ID and verified by a code received on this phone number (via text or call).
When you can’t receive the verification code on your trusted devices, you can choose to get them on your trusted phone number.
To ensure you aren’t locked out, make sure youadd more than one phone number to your Apple ID. You can use your number and that of a close person like a spouse or parents. This way, if you lose your phone, the verification code can be sent to your spouse’s number.

How to generate 2FA login codes for Apple ID
Suppose you’re trying to sign in using your Apple ID but can’t receive the code Apple sends to your trusted devices or trusted phone number.

How to remove a trusted device from Apple ID
To remove a device from your list of trusted devices, you will have to remove it from your Apple ID. After that, it’s delisted from your Apple ID and, therefore, won’t receive 2FA codes.
Additionally, after removing a device, you can’t useiCloud,Find My, and several other Apple services on it. You can, however, sign in to this device using another Apple ID. Or, if you change your mind, you can sign in with the same Apple ID.
Here’s how to remove trusted devices for Apple ID two-factor authentication:
Using iPhone or iPad
Using web browser
Managing trusted devices
This is how you can add and remove trusted devices from your Apple ID. Use this only to delist old devices you no longer use.
Once you remove a trusted device, it should not show up in your list of devices under Apple ID. But if it does, that is because you’re using this Apple ID for App Store or some other service on that device. To fix this, sign out from these services orerase the device.
